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...
Background: I am using the STM32H747I-DISCO board and the BSP SDMMC example from the ST Repository as my starting point. I can provide my code if necessary but wanted to keep post as short as possible. I have looked at AN4838, AN4839 and AN5200 ST ...
Hello,I am using an ST7701S LCD over 3-wire SPI (CS, SCK, SDA) with my STM32.When I send the initialization commands from my ESP, I noticed the following:The first command of the sequence is not sent.The program seems to stop at the second stage, ar...
Hello. I created a DC-DC converter on a G4 series microcontroller. I use hardware FMAC, current mode as the regulator. My question concerns the overregulation of the output voltage level when the converter starts. I have a hardware power-off button o...
Hello Everyone,I hope this message finds you well. I am currently developing a USB Host application using the STM32H573I-DK and have encountered a persistent Hard Fault issue that I would like to seek your expertise on.[Environment Information]Target...
I'm using stm32u535 and would like to have zero crossing detection of supply voltage. I've requirement of 6ADC channels and all are configured in differential mode and adc clock is 25Mhz and resolution is 14 bit and dma circular mode is enabled. On c...
Hello ST Community, I am working on STM32N6 with an IMX335 camera sensor, ThreadX + USBX, and trying to stream live camera video over USB Type-C (UVC) to an external screen / PC. Current status: - Camera + ISP + DCMIPP pipeline is working correctly -...
Hi STM Devs!I would like to introduce a thread scheduling library - SuperTinyKernel (STK).Its GitHub repo: https://github.com/dmitrykos/stkYou can check capabilities in detail on GitHub but briefly STK can:Soft and hard real-time support: STK support...
helloDescription:I'm currently working with the STM32U585 and encountered an issue related to USART3Most of the time the code works fine, but it occasionally gets trapped in HAL_UART_IRQHandlerI am using the DMA Receiver Timeout (RTO) and DMA TX, may...
Hello,in our application, running on a H533RET6 and with no TZ enabled, we need to close debug ports in production.I preliminarly did some tests using CubeProgrammer: I generated password-based credentials (obk+bin files, which as far as I understand...
NUCLEO-F411REI have ADC1 to DMA in a circular buffer 4 samples long (ADC_VAL). I then use a TIM1 interrupt to send the contents via UART to a PC. int16_t ADC_VAL[4]; ... HAL_ADC_STart_DMA(&hadc1, (uint32_t *)ADC_VAL, 4); /* TIM1 callback */ void HA...
