I am starting a new project with the STM32L432. I need the RTC, but I don't understand how to manage the backup battery. This microcontroller doesn't have a dedicated VBAT pin. From what I understand, both the main power supply and the backup battery...
Hi guys, I was trying to implement HAL_UART_Transmit_DMA() since I am using freeRTOS. It auto trigger a reset for my stm32f427.Tried HAL_UART_Transmit(), everything works well. Only HAL_UART_Transmit_DMA() causing the reset, Did I missed anything? ...
Hello,I'm working with the NUCLEO-H7S3L8 microcontroller and trying to transmit data using SPI, but I'm encountering an issue where the TXDR (Transmit Data Register) is not updating.I have generated the code using STM32CubeIDE Version: 1.17.0 and SDK...
Hi.In my program, I am transmitting the following CAN IDs at a 20ms cycle:1. 0x0802. 0x1003. 0x15B4. 0x2155. 0x3156. 0x4157. 0x5158. 0x40DWhen continuing the periodic transmission, I have observed that sometimes No 4-8 do not flow on the CAN bus and ...
Hello ST,is there a document showing identical peripherals between STM32 MCUs / MPUs / types / families ?It would be really helpful before switching to another MCU / MPU to have an overview.Especially for the non-HAL users.Best would be evaluations l...
If I have 2 external devices, one mapped on GPIOC0 and another on GPIOG0 of the micro, so they generate the same EXTI0 interrupt, how is it possible to distinguish which of them is calling the interrupt? I mean, is it possible to read effectively the...
Hi Team,We are using the STM32H753VIH6 in our design.We are having MAC to MAC connection with Realtek GMAC port and STM MAC port.The schematics connections is in the attachment.Now we would like to generate 50MHz reference clock from STM32 to Realtek...
1. Setup OTPThe default OTP configuration of the chip is to boot from norflash, so you need to modify OTP to boot from EMMC. (Note: OTP can only be modified once, please operate with caution!)Open STM32CubeProgrammer software, check OTP_FUSES_STM32N6...
I am using an stm32c011 MCU and want to put my device into standby mode and then periodically wake it up (every 30s or so).I have seen guides which use the RTC to do that, but cube mx doesn't show me a WakeUp option on my RTCAm I missing something or...
