Pulse Gadget

This example program shows how to use pipwm (govattu library) features in real hardware implementation. Uses SSD1306 (128x64 oled I2C display) and matrix keyboard

simulated display

If ssd1306 is not available. It is also possible run this software with -simdisp=true command line option. In that case, updated content of display is printed to stdout.

and/or

simulated keyboard

If matrix keyboard is not available then it is possible to activate -simkey=true command line option

simulate all?

Two kind of simulations

run sofware with command

./pulseGadget -simhw

for getting "total simulation". No pwm signal is generated

sudo ./pulseGadget -simhw=true -simkey=true

for producing signal but with simulated 4x4 keyboard and ssd1306

4x4 button matrix

Software supports scanned 4x4 matrix keypad connected to GPIO pins

Keys are
