=MIPS scripting language for IC10 housings / chips=
MIPS is [[Stationeers]]' inspiration for the in-game scripting language called IC10. It runs on [[Integrated Circuit (IC10)|IC10 chips]] crafted at the [[Electronics Printer]].

==Registers==
Internal registers '''r?''': The IC contains 16 CPU registers, numbered '''r0''' to '''r15'''. From now on referred to as '''r?'''.
+
The IC contains 16 registers, numbered r0-r15. Think of these as variables in other programming languages. In fact, you can name them with the alias command (see below).
 
 
Device registers '''d? logicType''': Device registers are written to and from the IC. A device register is numbered '''d0''' to '''d5''' (select via screw), or '''db''' (connected device). From now on referred to as '''d?'''.
 
 
 
=== Logic and algorithmic with '''Internal registers''' ===
 
All calculations are exclusively performed to and from '''r?''' registers, or generally more understood as variables in programming. You can use aliases to give convenient names with the <code>alias string r?|d?</code>command (see below).
 
 
 
Internal registers can be manipulated in various ways.
 
* Write constant values <code>move r? (r?|num)</code>: Example: <code>move r0 2</code> sets r0 to the number 2.
 
* Calculate: Calculations are done to- and from these registers, like <code>add r? a(r?|num) b(r?|num)</code>. Example: <code>add r1 r0 3</code> adds 3 to r0, and writes to r1.
 
 
 
Note, for any kind of if statements or loop behaviours, knowing about labels, branching, and jumps is essential knowledge. See below.
 
 
 
=== IO to '''Device registers''' ===
 
Acronym '''d?''' stands for device, where ? is a number corresponding to the screw device selector on the socket.
 
You can also read/write to the device where the IC is planted in using device '''db'''.
 
 
 
Generally, there are up to 6 devices which can be set using the screwdriver '''d0''' to '''d5'''. A special device register '''db''' is the device wherever the IC is mounted upon. Very convenient for atmospheric devices where no separate IC socket is required.
 
 
 
Note, the IC is completely unaware where d? is actually connected to. So if you get a logicType error, check d? number, or check if the screw has been set opn the socket. An alias is only convenient to convey what is expected to be set on the d? screw, it does not actually set or program the screq.
 
  
* Read from device (load) <code>l r? d? logicType</code>: Reads logicType, like Pressure from a [[Sensors|gas sensor]], from device d? to register r?. Values can be read from connected devices and put into the register using the '''l''' (load) command. For example, if you want to load the state of a door. <br> Example: <code>l r0 Door Open</code> reads the 'Open' field of an object named 'Door', that would be connected to the IC housing of the chip.
+
To set a register directly (such as r0=2), use the <b>move</b> command. To read a value from a device, use <b>l</b> (load). To write a value back to a device, use <b>s</b> (set). Note that
* Write to a device (set) <code>s d? logicType r?</code>: Write a value from a register back to a device using the command <code>s d? logicType r?</code>. For example, if d0 is set to a door using the screwdriver, <code>s d0 Open 0</code> sets the 'Open' status of the d0 (a door) to 0, effectively closing the door.
+
like most machine languages, the <i>destination</i> goes first, so instructions always look like: action destination source.
  
=== batch IO to - '''Device registers''' ===
+
Here are some examples set a register, reading a value from a device and writing a value to device:
'''Batch writing''' needs to be done to a specific '''deviceHash''' instead of d?. Is unique per device type, which you can find in the [[Stationpedia]] entries.
 
* <code>lb r? deviceHash logicType batchMode</code>
 
* <code>sb deviceHash logicType r?</code>
 
Additionally, using the following batch commands, a '''nameHash''' can be provided to only modify devices with a certain name.
 
* <code>lbn r? deviceHash nameHash logicType batchMode </code>
 
* <code>sbn deviceHash nameHash logicType r?</code>
 
  
'''batchMode''' is a parameter equal to 0, 1, 2, or 3. These are also defined as the constants '''Average''', '''Sum''', '''Minimum''', and '''Maximum''' respectively. The word or number can be used.
+
<code>move r0 10</code><br>Sets register r0 to the value 10
  
Combining one of these functions with the <code>HASH()</code> function can be advantageous:
+
<code>move r0 r1</code><br>Copies the value of register r1 to register r0
  
<code>lbn r0 HASH("StructureGasSensor") HASH("Sensor 1") Temperature Average</code>
+
<code>l r0 d0 Temperature</code><br>Reads the Temperature parameter from device d0 and places the value in register r0.
 
 
This code will load the average temperature of all gas sensors on the network named "Sensor 1" onto register '''r0'''
 
 
 
If the batch read (lb/lbn) is done on a network without any matching devices the results will be as specified in the table:
 
{| class="wikitable"
 
|+ Batch read with no devices
 
|-
 
! Batch Mode !! Result
 
|-
 
| Average (0) || nan
 
|-
 
| Sum (1) || 0
 
|-
 
| Minimum (2) || 0
 
|-
 
| Maximum (3) || ninf
 
|}
 
 
 
=== Examples ===
 
 
 
Here are some examples demonstrating all three operations:
 
 
 
<code>move r0 10</code><br>Sets register '''r0''' to the value 10
 
 
 
<code>move r0 r1</code><br>Copies the value of register '''r1''' to register '''r0'''
 
 
 
<code>l r0 d0 Temperature</code><br>Reads the Temperature parameter from device '''d0''' and places the value in register '''r0'''.
 
 
Note: not all devices have a Temperature parameter, check the in-game stationpedia.

It's recommended to use labels (like: ''someVariable'') instead of a direct reference to the register. See '''alias''' in section [[MIPS#Instructions|Instructions]].

=== Special registers ===
 
 
There are two more registers. One called '''ra''' (return address) and one called '''sp''' (stack pointer). The '''ra''' is used by certain jump and branching instructions (those ending with '''-al''') to remember which line in the script it should return to. The '''sp''' tracks the next index within the stack (a memory that can store up to 512 values) to be pushed (written) to or popped (read) from. Neither '''ra''' or '''sp''' is protected, their values can be changed by instructions like any other register.

Neither '''ra''' or '''sp''' is protected, their values can be changed by instructions like any other register.
 
==Stack Memory==
 
;push r?: adds the value  '''r?''' and increments the '''sp''' by 1.
 
;pop r?: loads the value in the stack memory at index <code>sp-1</code> into register '''r?''' and decrements the '''sp''' by 1.
 
;peek r?: loads the value in the stack memory at index <code>sp-1</code> into register '''r?'''.
 
;get r? d? address(r?|num): loads the value in the stack memory at index <code>address</code> on provided device into register '''r?'''.
 
;getd r? id(r?|num) address(r?|num): loads the value in the stack memory at index <code>address</code> on provided device id into register '''r?'''.
 
;put d? address(r?|num) value(r?|num): adds the value to the stack memory off the provided device at index <code>address</code>.
 
;putd id(r?|num) address(r?|num) value(r?|num) : adds the value to the stack memory off the provided device id at index <code>address</code>.
 
 
As mentioned previously, '''sp''' can be both written to and read from any time. When reading ('''peek''' or '''pop'''), '''sp''' must be between 1 and 512, inclusive. While writing ('''push'''), '''sp''' must be between 0 and 511, inclusive.
 
 
Stack memory is persistent on logic chips. This means that if you have a logic chip and push values to the stack, the code that pushes those values can be removed and the stack will retain those values.
 
 
Note that this does not carry over to any other logic chips which receive the program of the original; They will need to have their stack memories programmed individually.
 
 
'''Stack Traversing'''
 
 
Traversing the stack can be done similarly to how an array would be traversed in some other languages:
 
{{MIPSCode|
 
#this will traverse indices {min value} through {max value}-1
 
move sp {min value}
 
loop:
 
add sp sp 1
 
peek r0
 
 
#do something here with your stack values (loaded into r0)
 
 
blt sp {max value} loop
 
 
#continue on
 
}}
 
 
Alternatively, you can use the pop function's decrementing to make a more efficient loop:
 
{{MIPSCode|
 
move sp {max value}
 
add sp sp 1
 
loop:
 
pop r0
 
 
#do something here with your stack values (loaded into r0)
 
 
bgt sp {min value} loop
 
 
#continue on
 
 
}}
 
  
 
==Device Ports==
 
==Device Ports==
 
ICs can interact with up to 6 other devices via d0 - d5, as well as the device it's attached to via db. To change or set a device, use a screwdriver and adjust the device in the IC housing. You can read or set any of the device's properties, so it is possible to do things like read the pressure or oxygen content of a room on the same Device port.

You can read or set any of the device's properties, so it is possible to do things like read the pressure or oxygen content of a room on the same Device port.  
  
Additionally, is possible to set other IC housings as devices, allowing you to create programs that run across multiple ICs together. For example, an Gas Mixing IC could check the ''' Setting''' field of a Atmosphere Sensor IC and act based on the value of the sensor chip.
+
The '''l''' (load) or '''s''' (set) instructions you have to read or set these values to your device. Examples:
 +
 
 +
<code>l r0 d0 Temperature</code> #Reads the '''Temperature''' from an atmosphere sensor at device port '''d0''' into register '''r0'''.
  
The '''l''' (load) or '''s''' (set) instructions you have to read or set these values to your device. Examples:
+
<code>s d1 Setting r0 </code> # Writes the value of the register '''r0''' to the device on port '''d1''' into the variable '''Setting'''.
{{MIPSCode|
 
#Reads the 'Temperature' from an atmosphere sensor
 
# at device port 'd0' into register 'r0'.
 
l r0 d0 Temperature
 
}}
 
{{MIPSCode|
 
# Writes the value of the register 'r0' to the
 
# device on port 'd1' into the variable 'Setting'.
 
s d1 Setting r0
 
}}
 
  
 
==Labels==
 
==Labels==
 
Labels are used to make it easier to jump between lines in the script. The label will have a numerical value that is the same as its line number. Even though it's possible to use a labels value for calculations, doing so is a bad idea since any changes to the code can change the line numbers of the labels.

+
<br><code>j main</code>
j main # jumps back to 'main'

==Constants==
 
==Constants==
Instead of using a register to store a fixed value, a constant can be made. Using this name will refer to the assigned value. With the help of Constants you can save register places.
+
Instead of using a register to store a fixed value, a constant can be made. Using this name will refer to the assigned value.
{{MIPSCode|
+
<br><code>define pi 3.14159</code>
# defines a Constant with name 'pi'
+
<br><code>move r0 pi</code>
# and set its value to 3.14159
 
define pi 3.14159
 
}}
 
  
You can use these constants like any other variables (see: alias in section [[MIPS#Instructions|Instructions]]). Example:
+
==Indirect referencing==
{{MIPSCode|
+
This is a way of accessing a register by using another register as a pointer. Adding an additional r infront of the register turns on this behaviour. The value stored in the register being used as the pointer must be between 0 to 15, this will then point to a register from r0 to r15, higher or lower values will cause an error.
# set the value of register 'r0' to the value of constant named 'pi'.
 
move r0 pi
 
}}
 
  
==Indirect referencing==
+
<code>move r0 5</code> stores the value 5 in r0
This is a way of accessing a register by using another register as a pointer. Adding an additional r in front of the register turns on this behaviour. The value stored in the register being used as the pointer must be between 0 to 15, this will then point to a register from r0 to r15, higher or lower values will cause an error.
+
<br><code>move rr0 10</code> is now the same as <code>move r5 10</code> since r0 has the value 5, rr0 points at the register r5
{{MIPSCode|
 
move r0 5 # stores the value 5 in r0
 
move rr0 10  
 
# is now the same as 'move r5 10'
 
# since r0 has the value 5, rr0 points at the register r5
 
}}
 
  
 
Additional r's can be added to do indirect referencing multiple times in a row.

==Network Referencing / Channels==
+
==Debugging advice==
 
+
The value stored in a register can easily be seen by writing it to the Setting parameter of the IC housing, this has no sideeffects, too see the value just stand close and look directly at the housing (<code>s db Setting r0</code>).
All cable networks have 8 Channels which can have data loaded from/stored to via a device and connection reference. Connections for each supported device are listed in the stationpedia. All 'connections' a device can make are a connection (pipe, chute, cable), but only cable networks have channels.
+
<br>To check if a certain block of code is executed, use the above trick but with a number that you choose, like the line number (<code>s db Setting 137</code>).
 
+
<br>The configuration card can be used to manually check the data values stored in all connected devices.
The 8 channels (Channel0 to Channel7) are however volatile, in that data is destroyed if any part of the cable network is changed, removed, or added to, and also whenever the world is exited. All these channels default to NaN. Strictly speaking, they default to what we would call "quiet NaN", in that its not an error it simply means its not a number yet. Recommend you use these channels for reading and writing between networks, rather than as a data store. This effectively means an IC can read all the networks for all devices to connected to it, so not just their own local network, but any networks any device they can reference is connected to.
 
{{MIPSCode|
 
# d0 is device zero, and the :0 refers
 
# to that device's 0 connection
 
l r0 d0:0 Channel0}}
 
 
 
For example: on an IC Housing, the 0 connection is the data port and 1 is power, so you could write out r0 to Channel0 of the power network of the Housing using <code>s db:1 Channel0 r0</code>
 
 
 
==Comments==
 
Comments can be placed using a '''#''' symbol. All comments are ignored by the game when it reads commands. Below is an example of valid code with two comments.
 
{{MIPSCode|
 
alias MyAlias r0 # Text after the hash tag will be ignored to the end of the line.
 
# You can also write comments on their own lines, like this.
 
}}
 
 
 
==Debugging advices==
 
The value stored in a register or variable can easily be displayed by writing it to the Setting parameter of the IC housing. This has no side effects. To see the value, just stand close to the IC housing and look directly at the housing.<br>
 
<code>s db Setting r0</code>. # sets/writes the value of register '''r0''' into the parameter '''Setting''' of the IC Housing('''db''')
 
 
 
To check if a certain block of code is executed, use the above trick but with a random number that you choose, like the line number.<br> This example will display the number 137 on the IC housing.<br>
 
<code>s db Setting 137</code> # sets/writes the number 137 into the parameter '''Setting''' of the IC Housing('''db''')
 
 
 
Always use unique names for labels. When a label is named after a MIPS keyword like "Temperature:" or "Setting:" the original meaning of the keyword is overwritten, so when an instruction tries to use it an error will occur.
 
 
 
A [[Cartridge#Configuration|configuration cartridge]] installed in a [[Handheld_Tablet|tablet]]  can be used to see all available values and configuration parameter for all devices you focus on.

All approximate functions require additional argument denoting how close two numbers need to be considered equal. E.g.: <code>sap r0 100 101 0.01</code> will consider 100 and 101 almost equal (not more than 1%=0.01 different) and will set r0 to 1. The exact formula is <code>if abs(a - b) <= max(c * max(abs(a), abs(b)), float.epsilon * 8)</code> for <code>-ap</code> and is similar for other approximate functions.
