Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello everyone, I'm working on the LORA pingpong example, and in the pingpong_process code, where I receive the data, I want to print it aswell. The current code that's running is this: if(RxBufferSize > 0){ memcpy(receive_data, BufferRx, sizeof(Bu...
Hi, 2 questions:how to develop doubleframebufferis clear framebuffer time 10ms top performance (-Ofast 160MHz)?Details:I'm experimenting with STM32U5A9J-DK round display board. After many trials and errors, comparing U5 examples with much richer ones...
After enable ADC in Cubemx, it is better if HAL_PWREx_EnableVddA() added automatically.
Hello,When I execute StartEcc() in a code without TrustZone enabled, it sets the ECCE & ALE bits of RAM CR as expected. but in my current project even after StartEcc() is executed, ECCE & ALE bits are 0, which means it is not able to turn the ECC fea...
Hi, I have a question about the internal SRAM1 in the STM32F769NI.Do I need to do anything special to retain the data in SRAM1 on reset?If data retention is established by default, do you know how it works?
Hi, I am working on a project where we need USB DFU on the STM32H730. I have selected the USB DFU function in the .IOC, compiled and uploaded to the hardware, but when I try uploading a new program both via this online DFU Tester (https://devanlai.gi...
