Hi there!here i'm for ask another help. I use STM32G031 for write and read eeprom 24LC01B , and i work with where Address = 0x01;HAL_I2C_Mem_Write(hi2c, DevAddress, Address , I2C_MEMADD_SIZE_8BIT, &val, 1, 100);so if i wrote 7 byte everythingh work p...

Hi there ! I start a project with STM32G031k8. This board i'm gonna make is a RS485 slave on the pin 4-5-6-7 of GPIOA i put a dipswitch with pullup resistor , and i read in this way: uint16_t Add = ( 0x00F0 & GPIOA->IDR)>> 4 ; right now my add is 5...
