SMT32_L4 non multiplexed asynchronous RAM IS61WV102416BL addressing issues

Hello everyone,For a university Project we are using a STM32L4 MCU together with the  IS61WV102416BL non multiplexed asynchronous SRAM. I followed the Application note which can be found at:https://www.st.com/resource/en/application_note/dm00228015-u...

STM32 application split up

I'm working on an STM32L432KCU microcontroller. I want to develop two applications on the same MCU:An "OTA" app. This would load first. It uses a cellular modem to check for, and download firmware updates, and overwrite the existing application. Othe...

Trap NULL pointer dereference

Hi,We are using STM32H750 for the new product development. The IDE is IAR Embedded Workbench and the RTOS is uC/OS-II.We found that it is OK to dereference NULL pointer on STM32H750. Any way to trap NULL pointer dereference to generate an access vio...

While configuring CAN FDCAN1 Tx and FDCAN1 Rx for NUCLEO-G474RE , the loopback mode is working but while connecting with Canoe Analyzer in Normal Mode, I am receiving frame error(Frame format : "FD mode without Bitrate Switching" ).

The CAN transceiver IC, i am using : TJA1057GT/3 , and I am seeing the some data waveform on oscilloscope but decoding is not happening. the baud rate varies for the CAN FD is from ~300kbps to 1Mbps(large fluctuation).  Clock Divider : Divide kernel ...

I2C LL

I have some questions about how to start I2C on LL.Firstly, I rewrote the HAL code in LL and was a little surprisedWhy does it take so much code to read the data? virtual Status::statusType ReadByteArray(uint8* buffer, uint32 size) override { if (...
