Arduino for STM32

I have attached the schematic and the full code for the PWM motor control. Both are available under GPL V3.

The schematic was developed using KiCAD.

Best regards,
Steve

Greetings, ABOSTM, you are my hero today. I now have a working sketch which I will post here for any others who have an issue with getting more than one PWM going and need a known good example.

I've attached a screen shot from my scope showing the two PWM signals alternating from 10% duty to 90 ...

You can try this instead of analog API:

I found my answer in a post made by fredbox (Thanks!) and here is the working test program with the new stuff for the next person who has this trouble:


#include<Wire.h>
#include <LiquidCrystal_I2C.h>
#define pwm_pin PB9
long int loop_cntr;
LiquidCrystal_I2C lcd(0x27, 20, 4);

TIM_TypeDef ...
