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.
First install via npm:
npm install --save lp5562
Then include it in your project
// if using typescript or ES6 modules// or if using ES5;
Typescript definitions are included in the package. The function's signature is:
assemble(program:string) : Uint16Array
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`.engine1set_pwm 255flash:ramp 200, -128ramp 200, 128branch 5, flashramp 200, -128ramp 200, -127end, i`;
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.
