Arduino for STM32

working ported code for stm32f1 (the blue pill) :mrgreen:

#include <Arduino.h>

#define CPU_MHZ 72
#define CHANNEL_NUMBER 8 //set the number of chanels
#define CHANNEL_DEFAULT_VALUE 1100 //set the default servo value
#define FRAME_LENGTH 22500 //set the PPM frame length in microseconds (1ms ...

thanks , but that project convert ppm to serial i need the invarce

esp code for ppm /// it works

#define CPU_MHZ 80
#define CHANNEL_NUMBER 8 //set the number of chanels
#define CHANNEL_DEFAULT_VALUE 1100 //set the default servo value
#define FRAME_LENGTH 22500 //set the PPM frame length in ...

can any one help me to write a simple code to genaraite ppm signal on stm32 i had only found codes for atmega and esp null for stm
i am geting trouble at porting it (dont have good idia about timer and counter)
