    LP5562

    This package is a quick and dirty assembler for the Texas Instruments LP5562. Package is primarily written so that an open-source toolchain can be provided for the LED controller used in the keyswitch.one project.

    Usage

    First install via npm:

    npm install --save lp5562
    

    Then include it in your project

    // if using typescript or ES6 modules
    import {assemble} from 'lp5562'
     
    // or if using ES5
    var assemble = require('lp5562').assemble;

    Typescript definitions are included in the package. The function's signature is:

    assemble(program:string) : Uint16Array

    where program is the string representation of the assembly program, and the resulting Uint16Array is an array of 48 16-bit WORDs representing the memory map of LP5562's program space.

    assemble(`
      .engine1
      set_pwm 255
     
      flash:
        ramp 200, -128
        ramp 200, 128
        branch 5, flash
     
      ramp 200, -128
      ramp 200, -127
      end, i
    `);

    Produces:

    Uint16Array[ 65344, 65283, 32515, 33186, 65283, 65027, 208, 0, 0, 0, ... 0 ]
    

    All data is provided in big-endian format (as the LP5562 is an 8-bit device). Feed the Uint16Array#buffer to a Uint8Array or use a DataView if you need a different data representation.

    install

    npm i lp5562
