Hello guys, I am trying to integrate and EEPROM into my system (based on STM32H7). I managed to write a struct into the EEPROM. However, the data that I read is different from the data that I have written. Is this a known problem with EEPROMs? Any h...
Hello Guys, I have a AT24CM02 EEPROM which uses I2C to communicate with a STM32H7 MCU. I need to store some float values into the EEPROM, but I do not know how. I appreciate any suggestions. Thank you and best regards, Vouria
Hi every body,I hoped to supported from community, friendlly technichians so much,I need embedded my program from Simulink to MCU STM32F411 on Discovery kit to and run real-time in External-Mode, so Vitual COM Port is very important.I Installed Drive...
Hi,Is there any way to divide flash sectors into smaller parts? I have to store data into the flash and want to be able to delete it when I want. Currently, I am using two sectors for that purpose and when I want to erase some data copying whole data...
Hello everyone, im currently studying DMA on STM boards, and im trying to send I2C messages from a mcu SLAVE (arduino) to STM32F407VET6 master, but both SCL and SDA lines is held low, it doesn´t happen when im using I2C in polling or interrupt mode, ...
I want to save 2 strings of 127 bytes of data in 1 page. 1 page is 256 bytes each. Whern I try to read and write 127 bytes of 1st string, it works successfully. But when I try to append 127bytes of 2nd string,it does not read and write data properly....

I got an STM32F401CC6 blackpill module.I tried to upload via Arduino IDE the demo project blink.After succefull upload the board does not work.It lights only the red led and not the blue one.Is there any way to recover it?Thank you ,Yannis
Im working on stm32l4 series ,using external eeprom , eeprom writes four variables in 4 EEPROM addresses succesfully,but while reading EEPROM it only reads last (4th) variable on all 4 EEPROM address,Im try all methods adjusting delay ,EEPROM addre...
I try to use the timestamp function from can_message.h to know the timestamp of a message received on the CAN.But the value is every time 0. Is it a knowed bug?Because I use this function with another hardware without problem.With STM32 I'm not able ...
