I am trying to a develop application that have Temperature sensor and i want to send data to app. but when the device is not connected then i want to put BNRG2A1 in low power mode. what is the way to do that i am using X-CUBE-BLE2 software package in...
Dear all,I am almost new to SMT32 world.I would like to use FMC to write to an external DAC, Analog devices AD5447. I attach datasheet for easy reference. It is 12bit, 10Msps and parallel interface.I am using Nucleo-F439ZI board and STM32CubeIDE to t...
Hello guys,I had recently a problem with executing LDREX instruction on the STM32H755 when MPU was activated for the specific memory region that covered the address accessed by the LDREX instruction. After executing LDREX instruction I got immediatel...
Hello dear friends,I use F4 series MCUs. I am looking to send UART data via DMA and receive data in interrupt. How can I reach this goal? I am able to send data via DMA and receive data in interrupt, but the problem is in simultaneous use of DMA for ...
Hello everyone,I'm using 4 timers of a stm32 nucleo board to count the increments in encoder mode. 2 timers are 16 bit and 2 others are 32 bit. The increments can be between -1,000,000,000 and +1,000,000,000.With 32 bit timers, there is no problem be...
Hi all, I connect to a BMS board (TI BQ4050) using the HAL SMBUS driver.In my old platform, STM32F401, I can read registers from the BMS. Somehow, identical code on a STM32F446 fails half way through the read transaction (HAL_SMBUS_Master_Receive_IT)...
Hello!Can anybody explain why STM use HAL and what is the difference and hierarchy between low layer API, CMSIS, HAL, SPL ?I always worked with just header files, but now all distributes API and I cant construct these API and their necessary in my he...
Hi,I'm new to STM microcontrollers.I was wondering if you could help me with running external ram IS42S16400 on STM32F429 using SDRAM interface.I'm attaching my project.Thanks a lot for your help :)
