STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi all. I'm a CS major with a decent knowledge of C, C++, and Python, but my summer internship has tasked me with installing NuttX onto an STM board and I'm a bit lost. I have never used Linux before and I have never dealt with real time operating sy...
Hello guys. As indicated in the title, I have an STM32H7B3I-DK board here with me. I am trying to play with it but currently having a hard time to load the code to the board from Keil MDK v5.23. When I compile the project and press a Download button,...
Hi, I hope you are well!I get stuck on the same issue since a few months:I stream multiple audio files (.wav), at the same time and continuously. After 24 hours of streaming, SD card files start to be corrupted (data is wrong) and when I inspect the ...
Hello,I am using UART4 from a STM32F2. I am sending a data then my RXNE FLAG from SR register go from 0 to 1. Without doing anything (no read of the DR register and no clearing manually the flag) it go back to 0 after some time. So I am missing the d...
I am using the STM32H743I-EVAL2 and have been trying to get the SD card initialization working. During the execution of HAL_SD_Init() --> HAL_SD_InitCard() --> SD_PowerON(), HAL_SD_ERROR_CMD_RSP_TIMEOUT is returned.I was originally using code generat...
I've enabled the I2C controller and ask it to send a start condition on the bus, and it does, however, as soon as I write a data byte to the TX register, it releases the bus and raises an arbitration lost flag. How can this be possible when there is...
While testing the exception traps routines I ran into an odd problem with the SRAM2 parity check on an STM32L496. As part of a unit test I force a usage error by attempting to read from 0x3000 0000, an invalid address. The usage vector is called co...
Hi - I took a new Flip32 Flight controller board out of its sealed bag and reflashed the latest clearflight firmware (cleanflight_2.5.0_NAZE.hex) using the Flash Loader Demonstrator onto the board in Boot mode. ( I also tried clearflight configurato...
I am using the adanced control and the general purpose timers witch the STM32F334K8T6 to drive one half-bridge and one full-bridge.The problem lies with the full bridge:I use the general purpose timer with two times asymmetrical PWM (center aligned m...
Hi,I'm using an STM32F334 in a Nucleo development board. I have flashed the device both with STM32 ST-Link utility and after finishing, I connect the development board to an external supply and the MCU does not start running unless the RST button is ...
