Arduino for STM32

Thank you, all clear

normally, the eeprom 'isn't there', but that if the vendor puts it on the board, you can probably use it. as it seemed it is connected at i2c1, as for the i2c address, you would either need to consult the specs/manual for the eeprom or probably use some 'i2c scanner' sketch to probe for it. probabl...

So many thanks mate for you reply So the chip it's already configured and programed from factory and just I need to upload my sketch with st-link, great :D About the eeprom, sorry but I still don't understand, I'm going to need to read/store few bytes in eeprom on runtime operation, Do I need that e...

Hola, I just finish my prototype with this STM32G030C8T6 board https://i.ibb.co/85kcGtc/mem.jpg The board it's too big, I only need few GPIOS and get rid of the LDO, USB and that, as I have the official Schematic, I'm going to try to make my own small board design just matching exactly the same comp...

Hola, I'm a bit lost with this board in order to power up with 3.3v, the board it's NUCLEO-G031K8 and Datasheet As per manual, I remove SB3 and SB2 (SB2 it's default off) solder bridgeS but I'm not able to power up it from 3.3v, the power led it's ON but seems the code it's not running When the boar...

Thansk both to still help me out with this thing I made another test, I created a 10000ms interval pulse from external generator, and I'm printing millis()/micros() interrupt from the stm32g030 and a esp32, esp32 prints 10000.0xx ms (few uS off) and stm32g030 prints 1003x ms (+30ms drift) , so again...

you have a delay(2) in there, it would add 2 ms every true condition in the if block and power_on+=10000; should be in the loop() part of the code. either way instructions takes cycles to run and the call to millis() could consume quite a few every time the if(millis() - begin >= duration) clause i...

your code is to blame. try this instead: power_on+=10000; //increment the power_on time I don't got your point, anyway I tested with exactly same results I'm not an expert and I understand my code may be not the best but I tested before upload here on an ESP32 and I got 10.000008, only 8us drift An...

Hola!, I found the pefect SMT32 STM32G030C8 board for my project, I'm looking to boot from power off as fast as possible and this model boot up into the loop in under 2ms , however I realize that clock accuracy it's way off, I'm talking about 150ms drift every 100 seconds :shock: I don't know if thi...

thank you all very much for your answer, after buying and testing several modules by your advice, I have definitely opted for the msp430.
