Hi Team,We are currently working on a design using the STM32U5A5QJI6Q microcontroller in a BGA package, implemented on a 4-layer PCB. During the hardware development phase, we inadvertently omitted the external pull-up resistors on the I2C lines, spe...
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...
Hi , allI am currently working on a project using the STSPIN32G4 together with the STM32 Motor Control SDK (MCSDK). I would like to add the internal Temperature Sensor to monitor the MCU temperature.In STM32CubeMX, I have already enabled both the Tem...
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 Friends,Most STM32 based Evolution / Development Board has Crystal 32.768 Khz and Boot switch connected. In my Custom design board , I do not need RTC Function and Bootloader to load.8 Mhz Crystal is used for Master Clock. Can I remove 32.768 k...
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...
