Resolved! STM32H747I-DISCO: FDCAN1 TX not showing output in normal mode on PD1/PD0 (D3/D2)
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...
STM32U5G9 OctoSPI Memory-Mapped Mode with MX35LF1G24AD NAND Flash
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...
what do they mean by UART multibuffer communication?
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...
APB clock to RTC required for the RTC to be able to wake from sleep?
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 ...
STM32N6 in Nucleo XIP mode
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...
Issue with SDIO Initialization Causing MCU Communication Failure on Custom STM32H747 Board
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 ...
STM32C011J4 phantom pull-up on on PA12 [PA10] in ADC_IN12 mode
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...
what does selecting the alternate function of GPIO really do ?
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...
Resolved! VBAT on STM32U5G9J-DK1
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...
