Arduino for STM32

lots of answers here : https://github.com/stm32duino/Arduino_C ... 2/wiki/API

this code works : HardwareSerial Serial3(PB11, PB10); /// USART3 works uint64_t millis_duration = 100, millis_begin; void setup() { Serial.begin(115200); // USB Serial3.begin(19200); } void loop() { if (millis() - millis_begin >= millis_duration) { // debug uart millis_begin += millis_duration; Seri...

- you rather use a terminal emulator in order to see your outputs , so you do no more need to plug/unplug
- DAPLink is for MBed , and will work for other IDEs , but for Arduino , I really fear it won't work , so far

If I send information by Serial.print(), I can't see it over STLink-connection? I still need a USB to Serial-adapter? STLink can't handle serial (UART like) signals , so : - yes , use a USB to Serial-adapter - or a DAPLink (if it works with arduino ?) - or , if your informations are for debug , use...

Hi Jürgen , imho. : - (STM32G030F6P6 had been a better choice) - you rather continue to use your programmer for devices without USB , so you don't worry about BOOT0 - PA9 & PA10 can't be used out of the box for bootloader , because they are not connected to the pins by default ; may be you can u...

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"...
