Hello All , I am using UART6 of STM32H7 series MCU for reception of 9 Byte data . UART is losing first byte when receiving data on UART using interrupt. Setup: 1. I am using full duplex RS485 (Modbus) 2. I have 2 MAX485 IC one for reception & anot...
Hi Team, I am facing an issue regarding the open bootloader. Recently, I downloaded the open bootloader source code for the STM32U0 boards, and I was successfully able to load hex files via the STM32Cube Programmer over UART. However, I encountered a...
I get the following error when trying to debug an STM32H757 with SWO enabled. Failed to enable SWV configuration.Failed to execute MI command:-data-write-memory 0x5c003010 x 4 0x77etc...It would seem the debugger (ST-link v2) is not able to read the ...
Hello everyone,I'm working on a project where I need to transmit audio data from two microphones (left and right channels) over UART from an STM32 microcontroller. The audio data is initially sampled at high resolution (32-bit), but I’m converting it...
I'm using the STM32F407T6 for the first time and would like to be able to communicate with my computer using TTL.I'm trying to transfer the data by DMA but why the RX interrupt is not triggered after confirming the receipt of the data I want to recei...
Hi, I am using STM32H563 Nucleo board, and found the PLL1VCOSEL bit of RCC PLL clock source selection register.There are duplicates in the settings.Does anyone know why is the settings duplicates?I would like to know why and use case.
We have designed a boards, main board has STM32H742VGT6 and it is connected to Microchip PHY IC KSZ8091RNBCA in RMII Mode, Onboard Clock 25Mhz for PHY) we have tried basic configuration such as enabled ETH, LWIP Stack.we are using STM32CubeIDE 1.13...
The attached code configures UART communication to wake up a microcontroller in sleep mode as soon as a frame is received. In sleep mode, the micro waits for data on the UART interface, and when a UART frame is detected, it automatically wakes up t...
Hello all, I'm new to STM32, I have been given a project to display the time and date on either an 16x2 lcd or an oled display using the internal RTC of my board. I have the STM32 Nucleo f401re.Can somebody help me?Thanks and Regards
I am trying to communicate with CAN, but it seems that I am not receiving Rx. I would like to know the reason for this static void MX_CAN2_Init(void) { /* USER CODE BEGIN CAN2_Init 0 */ /* USER CODE END CAN2_Init 0 */ /* USER CODE BEGIN CAN2...
