I am having problems trying to use the HAL_SPI_TransmitReceive function. I am using STM32CubeIDE along with the STM32U5G9J-DK2, I am configuring my side as a full duplex slave using the following parameters:I am working with an embedded processor tha...
I cannot figure out which pins to connect to I2C on the STM32F070F6T6 chip. AN2606 says to use PB6/PB7 which do not exist on this part. The only pins that are mapped to I2C1 are PA9/PA10 or PF0/PF1 according the data sheet. My first spin of a boar...
HelloI'm always confused with the ADC clock config of H7 devices. ok, H7 is not a device for noob but ever after spending days reading datasheets, users manual, appnote, and filling spreadsheets, when starting cube MX, you will always find that the c...
Hi all,I'd like to use the RTC as a keeper of real-world clock. It would get synchronized with a (S)NTP server once a day. The RTC would get queried multiple times a day for the current time. The main challenge is that I'd like the timestamps to have...
Hello,with an ESP8266 I execute an erase memory command for the STM32F413CGU6 and when the sector is erased, the STM32 always performs a reset. The sector is erased afterwards, but the ESP doesn't have acces to the Boot0 pin and afterwards the STM32 ...
Hi,I'm using the NUCLEO-H743ZI2 board and I'm trying to interface it with an external DAC MCP4922 via SPI.As explained in the documentation, the CS pin is very important because it is used to mark the end of a transmission for the DAC to put the rece...
