Arduino for STM32

Hi , here is the code : timer17.setMode(1, TIMER_OUTPUT_COMPARE_PWM1, PA7_ALT3); // AF1 = TIM17_CH1 timer17.setMode(1, TIMER_OUTPUT_COMPARE_PWM1, PB7_ALT2); // AF1 = TIM17_CH1N /// mashes PA7 = CH1 TIM17->CCR1 = 5; timer17.setPrescaleFactor(170 - 1); // G431 is 170MHz timer17.setPreloadEnable(true);...

thanks !
maybe it works , but 10 time too slow ...

I don't have your chip but I do have a set of routines for G030. you can likely modify them for your chip, if not compiling directly.

oh yes , thanks , in addition G030F6P6 will probably be my next one

seemed to be priced at modestly low(er), as compared to some simpler boards or chips

probably because the chip itself is just $2 in China

for the comparator , the solution is here : https://www.stm32duino.com/viewtopic.php?p=13269#p13269 for the HSE , I am trying umejopa's code , but it doesn't seam to work , I have : - defined : #define HSE_VALUE (8000000UL) /// for a 8Mhz 24Mhz cristal that the board have - put : extern "C"...

thanks ag123 my problem isn't the RM or the code to generate , but the fact that the libraries I use then , are not allowed / known by stm32duino so , where can I find the "include files for the predefined registers" , and how can I import and declare them ? (it is a general problem of usi...

oh there is something else I'd think I'd want to explore on this chip/board is the comparators (...) I have just a question on how to program the comparator : nor the HAL or the LL or the LL structure worked for me on stm32duino , and I don't want to do it bare metal , so , ag123 , can you please s...
