This is a simple assembler for lp5523 led chips. You
can use it to convert the microcode from lp5523 engines
into human readable code and the other way around.
------------------------------------------------------------
The Assembly Language
------------------------------------------------------------
The assembly language consists of the following mnemonics:
* start
This must be specified at the beginning of each program.
* restart
Jumps back to the start.
* stop
Stops the engine.
* stopr
Stops the engine with reset.
* stopi
Stops the engine with interrupt.
* stopri
Stops the engine with reset & interrupt.
* send1, send2, send3
Sends signal to engine 1, 2 or 3.
* wait1, wait2, wait3
Waits for signal from engine 1, 2 or 3.
* set LEVEL
Sets output to LEVEL (0-255).
* sleep TIME
- TIME can be between 0 and 61
Does nothing for the specified amount of time. See
below for TIME value -> time in seconds calculation.
* fade TIME +STEPS
- TIME can be between 0 and 61
- STEPS can be between 0 and 255
- The '+' is important
Slowly increase the output by STEPS in the specified
amount of time.
* fade TIME -STEPS
- TIME can be between 0 and 61
- STEPS can be between 0 and 255
- The '-' is important
Slowly decrease the output by STEPS in the specified
amount of time.
* branch COUNT PC
- COUNT can be between 0 and 63
- PC can be between 0 and 95
Jumps (back) COUNT times to the opcode located at PC.
A COUNT value of 0 is interpreted as infinite.
Calculation of time in ms for a given TIME value:
if(value < 31)
return value * 0.49ms;
else
return (value-31) * 15.6ms;
--------------------------------------------------------
Usage
--------------------------------------------------------
Assemble lp5523.S into lp5523 machine code:
$ lp5523-as file.S > result.txt
$ echo "code" | lp5523-as > result.txt
Disassemble lp5523 machine code in assembly code:
$ lp5523-as -d input > result.txt
$ echo "code" | lp5523-as -d > result.txt
--------------------------------------------------------
Building & Installation
--------------------------------------------------------
Building:
$ make
Running Unit Tests:
$ make test
Installation:
$ install -m755 lp5523 /usr/local/bin
