Hello, everyone,I'm using a STM32L431CC and I'm having a hard time making an OTA firmware upgrade while my device has the RDP level set to 1.I've configured my Option Bytes on my bootloader and it appears to work correctly: the application code runs ...
Subject: SD Card Communication Issue in 4-bit Mode Iam using STM32F756ZG micro-controller.I am currently working on interfacing an SD card and have noticed an issue when switching between communication modes. The code executes as expected in 1-bit mo...
GreetingsI am trying to use 2 UART interfaces on the STM32L4xx series and echo what's received on 1 interface. I am receiving strings of unknown length on UART1 using the DMA and echo-ing it with the virtual com port (UART2). I intend on using receiv...
Hello ,I am working on a project with the STM32L562CET6 microcontroller and have encountered an issue with the timer interrupt callback function. 1. I configured TIM6 as the clock source for the microcontroller. Consequently, the HAL_TIM_PeriodElap...
I am working with the STM32U575 Nucleo board and trying to get the USB functionality working using one of the provided example projects "Ux_Device_CDC_ACM". I uploaded the code to the board with no problem and the USB-C is recognized by the host PC, ...
Hi Team,I am generating the PWM with center aligned mode by using the Timer1 at 62.5Khz.this PWM is going to Bridge circuit, at this time I have to read the ADC2 with this frequency hence I made ADC trigger with Timer1 out event.I am able to read but...
Good morning to everyone.I met problems while trying to drive a 16x2 I2C Lcd display with STM32F446RE Nucleo boards.I tried 2 different displays (Freenove and Arceli brand). It gives the same error.I tried 2 different STM32F446RE boards. It gives the...
Hello I'm developing RTOS environment of dual-core in STM32H757.I could refer to the examples provided by STM32, and I read the application note AN5617. I checked that the error is a exception "err1" under the function "rproc_virtio_create_vdev" in ...
I am currently trying to figure out at what byte the slave sends a NACK during an I2C master write transfer.When the slave sends the NACK after X bytes the error callback is called. Inside the error callback I am having trouble finding out at what by...
