Re: how to PWM Frequency stm32duino and resolution

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% dut...

Re: how to PWM Frequency stm32duino and resolution

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 *Instance = ...
