Online tool written in C/C++ that generates waveforms and exports them as arrays.
Online version: https://ppelikan.github.io/drlut
- live editing of waveform formula (C/C++ compatible syntax)
- available waveform presets:
- zeros, sin, cos, tan, ctan, sawtooth, triangle, white noise, gauss, hamming, hann, bartlett, flat top, sigmoid
- available output array formats:
- signed: int8, int16, int32, float (double)
- unsigned: uint8, uint16, uint32
- configurable amplitude and y-axis offset
- selectable int range behaviour:
- overflow or saturation
- selectable array output format:
- hexadecimal or decimal
todo:
* add array size computation in bytes/kbytes/megabytes and widget to display it
* "warning: 'BeginPlot' is deprecated"
* fix broken comments for formulas containing `\n` characters (buildLut() function)
* NaN and INF warning should be shown if detected (before type casting)
* fix clipboard (Ctrl+C and Ctrl+V) on web target
* add include guards to generated headers
