Resolved! STM32F042 boots in debugger only

Hi, I have designed a small project on the STM32F042F6Px MCU, and wrote a piece of software for it. Then I tried to run it outside of the debugger, and realized it won't boot. I've spent many hours on it already, and now I run out of ideas. It looks ...

Resolved! I2C SDA pin broken?

HiI am trying to configure I2C2 on an STM32F405RG on pins PB10/SCL and PB11/SDA, but I am getting very strange output on SDA. STM32 is I2C master. Using I2C example from STM32F4-Discovery folder.Using 4k7 ohm pull-ups to 3.3V.Is the output pin broken...

Resolved! 8bit data transfer on a SPI's 32bit DR register

Using STM32F767 Nucleo board and STMCubeIDE I am trying to transmit SPI data with data size of 8bit per transaction while I have setup my SPI2 in Full Duplex mode.Problem is that although I am able to transmit from MCU and receive on slave side the d...

Resolved! Is there a possibility to implement one shot function using RTC module (STM32L011)

Resolved! Is it possible to improve delay between two LL_SPI_TransmitData16

Hello,currently reading out an ADC sensor with SPI. The goal is to achieve a fast readout. Currently I am at around 200000 readouts per second, but I am wondering if this delay between two LL_SPI_TransmitData16 is because of the LL_SPI_ReceiveData16 ...
