Hello ST Community,I am working on the STM32H747I-DISCO board and trying to configure FDCAN1 for CAN FD operation.Setup:I understand this board does not include a CAN transceiver, but I want to validate FDCAN1 TX signaling before attaching one.I conf...
Hi everyone, I'm working on a project using the STM32U5G9 microcontroller and trying to interface it with a Macronix MX35LF1G24AD NAND flash via the OctoSPI peripheral. The goal is to enable memory-mapped mode so the external flash can be access...
Tell me about multibuffer communication in the registers of the UART. We have a description of the RXNE flag. "The RXNE flag can also be cleared by writing a zero to it. This clearing sequence is recommended only for multibuffer communication". It tu...
I find that I need to enable the APB clock to the RTC during sleep (i.e. by setting the RTCAPBSMEN bit in the RCC APBSMENR1 register) otherwise my code won’t wake after calling __WFI(); is the AI explanation below correct? The AI also says it’s EXTI ...
I have successfully completed using STM32N6 in LRUN mode and got the proper result and now I want to use Execute in place mode so please provide with all its related documents and videos.When I try to run appli code in DEV mode it does not run, it di...
Dear sir,In our custom board, we are using the STM32H747XIH6 microcontroller with Wi-Fi functionality. The Wi-Fi module part number is LBEE5KL1DX-883, and it is connected via the SDIO interface.We have properly configured the I/O pins in STM32CubeMX ...
HiI use CPU pin 6 as ADC input ADC_IN12. I take measurements every 100us and save them to buffer[100] via DMA.I have a 1M+10k resistor divider connected to ground to the ADC input.I measure a rectified sine wave signal within 0..2V.To my surprise, af...
Hello,I’m currently working with the STM32F103VET6 and experimenting with different peripherals to better understand how RCC, GPIOs, and timers interact — both from the block diagrams and the HAL layer.I've observed some unexpected behavior in the fo...
Hello,I have got an STM32U5G9J-DK1 and I want to use its VBAT pin which has been connected to the signal VDD_MCU, which is internal to the board, via solder bridge SB29. As far as my understanding of the data sheet goes, the VBAT pin is supposed to b...
On my dual-core STM32H747IGT6 I've got the CM4 doing data acquisition and processing, it's taking its output and storing it into shared memory (multiple possible destination buffers - some in SRAM1, some in SRAM2) for the CM7 to pick up. It's workin...
