Hi Folks,I have an issue with the RS485 Driver Enable Pin with the USART6 on an H7A3 (Nucleo).The Perhiperal is set up in CubeMX with "Hardware Flow Control (RS485) enabled.I have developed a driver using the Low Level functions.The Peripheral is set...
I'm trying to use the I2C line of an STM32G071G8U6TR to talk with an external device. I've used the STMCube to configure the pins to be I2C with pull ups and high speed which created this Init static void MX_I2C1_Init(void) { /* USER CODE BEGIN ...
Hi,I need a clarification about the configuration of GPDMA1 in linked list mode.I configure it using Cube MX v6.13.0, here some screenshots I took about the settings done: When I generate the code, in linked_list.c file I found the function MX_GPDMA1...
Hi,We've noticed that the STM32H533 micro-controller is not present in Longevity Commitment list.Is there a particular reason for this? We are planning to use this micro-controller in a number of new products going forward.Best regards,Michael Waite...
I am using STM32F469BIT6 on a custom PCB with IS42S16400J-7TLI external 8Mb SDRAM. On my previous board, I was using STM32F429ZIT6 with the same SDRAM (these mcu&sdram selected because they were used in STM32F429-DISCO) I was able to write/read data ...

Dear ST Community,I have been working on the firmware which contains the AT commands modem, Winbond flash memory. After some time I have relised the microcontroller is automatically getting restarted/. I had doubt on the hardware then we have redeve...
Dear Sir.I am using a board equipped with STM32U585 , The main clock is 32.768 khzsee included pic.PA8 is configured to drive LSE 32KHZ using the command__HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_HIGH);PA8 is fed to ECG MAX30001.On some boards MAX30001 r...
Hello,I have a STM32L152RE and I use PA1 (Pin type is FT 5v tolerant) as ADC_IN1. Vdd is 3.3V and the voltage on PA1 usually is around 5V and sometimes it drops to 2.5V ( when I need to take the measure). Several comments on various blo...
Hi, I have a STM32G474 connected to a Quectel LTE module via a uart4 and a GPIO pin.Under normal conditions is it possible for the CPU to boot from flash and when the quectel changes the level of the gpio pin of the STm32, the CPU jump to boot from u...
