Hello, I am making a project where i'm using usart2 as a virtual com port and where i'm making a CLI based HMI using teraterm , so there's a lot of diplay and hal_uart_transmit functions , it all worked fine until I added a DMA in the uart1 in order ...
The author of this how to get CANopenNodeSTM32 working video is very good (The length of the video is 3:31:33; The part that is pertinent to this post 57:05 - 1:18:22). Unfortunately, this video targets FDCAN (but I don't have this available; my chi...
I'm using LL_RCC_DeInit within a boot loader so that the clocks are in the reset state when the application is launched. However, LL_RCC_DeInit also clears the reset cause flags as its last action: /* Clear reset flags */ LL_RCC_ClearResetFlags();...
Hi, I need to update the firmware of my MCU from the UART. I mean without physically touching the BOOT pin, but only via serial commands (classic FW update of a product).I'm not an expert, but I tried searching on the internet and I saw that for thes...
Hi Mike, Thanks again for your previous support on the SPI interface.I have since moved to using the SDMMC interface instead of SPI for better performance, but I am still facing issues. Current Issue Summary:I can successfully mount the 32GB SDHC F...
Hi ST Community,I’m working on a JPEG encoding pipeline using the STM32N6570 Discovery Kit, and I’m running into an issue when storing both my input and output buffers in PSRAM.Setup:Both JPEG Encoder input (RGB_ImageAddress) and output (jpgBuffer) b...
HAL code for interrupt-driven SPI transmit attempts to fill a transmit queue, which uses up the 10 bytes I am transmitting. But, a TX interrupt is also triggered which grabs an extra byte past the end of the buffer and decrements the count which wra...
I have set up an I2S interface. The idea is to send it an initial HAL_I2S_Transmit_IT() request.In the ISR of SPI2 I'm sending the next HAL_I2S_Transmit_IT() and this way the transmit should be continously kept running.What happens is, that the SPI I...
Hello, I am currently attempting to get the ethernet set up on my eval board. The project goal is to use a timer on the eval board to trigger the board to call out to a PLC on my network to receive 8 values every 1 second. Those values will then be s...
Hi,I would like to use LPUART3 to proceed the UART communication with hardware control flow enable.However, I found that when the Send_UART_DATA there indeed has TX signal from LA, but CTS/RTS hasn't changed, only when system reset, those two pins j...
