Hi there I am using STM32L051 to talk to a RS485 transceiver and I am having problem with the receive part.System is as follow: laptop->FTDI USB converter-> Renesas transceiver -> STM32I want to update the single byte buffer when a character is detec...
Greetings,I have STM32Cube IDE installed, created some test apps, blinking LED's, RTOS threads, mutex and so on,writing on UART2 (virtual serial) is working well as I have working output on virtual COM port using putty on serial.I want to access UART...
Hi everyone,I am working on a power-saving application using the STM32G030 series IC, and I need to configure the UART to work at a baud rate of 9600 with an external low-frequency oscillator (32.768 kHz).My goal is to ensure that the UART baud rate ...
I am using stm32f779I eval kit. I am using example UART_HyperTerminal_DMA by en.stm32cubef7.I am trying to implement UART in DMA mode to transmit a simple string.So I have used CubeMX to generate the code and I have configured UART1 TX DMA in normal...
I Created a New Project for the Following MCU'sSTM32L072CZYSTM32F103C8T6STM32F401REI enabled the USB as Device and Also Selected Virtual Com Port as the Middleware and Generated the Project.Upon Loading the Respective Projects to the MCU's The USB Po...
I am using STM32H7B0VBT6 MCU.i want to transmit data using UART with DMA in normal mode.i am using "HAL_UART_Transmit_DMA(&huart4, &UART4_array[0], UART4_ARRAY_SIZE);"it sends only once , next time it do not work. Where i am doing wrong ? am I using ...
Hello! Not sure it's the right place to post. I have a custom board based on STM32F767. I'm using USB with VCOM port to communicate by UART. Basically it works (I mean, I can receive bytes from a terminal (I'm working on Ubuntu with STM32CubeIDE v. 1...
I got 2 STM32F446VET7 MCU board and I am trying to communicate each other with LoRa E220-400T30S.I cannot found any usefull libraries so I am trying to write one.I can communicate with modules from UART and setting configuration parameters.Both E22 m...
Hi,I am having uart baudrate problems while HSI clock as uart source clock. No problem with PCLK as source with the same uart. In Cube IDE (V1.16.0) and F7 software package (V.17.2), I get different values for HSI_CALIBRATION:Ide gets as 0x10 while r...
Hello,I am trying write a LoRa library to STM32F446VET7 in my application.In the LoRa E220-400T30S documentation, it tells me to set the UART settings for configuration mode to 9600 and 8N1 and to give 1 to M0 - M1 pins.After doing that I am trying a...
