Arduino for STM32

Yes thank you for the tip. I was able to come up with this code that works: #include <SoftwareSerial.h> SoftwareSerial myserial(PA7, PA8); // RX, TX uint32_t WriteRegisterValue = 254; uint32_t ReadRegisterValue; void setup() { myserial.begin(9600); delay (1000); myserial.println("test"); /...

Yes, from page 25 of the data sheet:

The device embeds an RTC and five 32-bit backup registers, located in the RTC domain of the silicon die.

Thank you.

I just uploaded the same code to a Blue Pill and it works. I believe it's an issue with the implementation of the backup registers with the STM32G030F6P6

I'm trying to access the backup registers of the STM32G030F6P6 with the functions in backup.h https://github.com/stm32duino/Arduino_Core_STM32/blob/main/cores/arduino/stm32/backup.h This is the code: #include <SoftwareSerial.h> SoftwareSerial myserial(PA7, PA8); // RX, TX uint32_t WriteRegisterValue...
