I have an ST link V2 and a custom board running at 3.3V generated by an on-board regulator powered from a battery. Google is sending me mixed messages about connecting VAPP (pins 1 and 2) on the ST link to VDD on the board. I'm a bit worried about de...
Hi, allI am trying to receive packet from uart3 and send them to uart2but the results of my trials are:transmit occurs every main cpu clocktransmit occur just oncewhich I thought was:receive packet from uart3 when packet arrived, independentlytransmi...
I am attempting to read a NEMA message from a GPS over UART.Im expecting the message to be about 75 chars/bytes long.Heres a sample of the data I'm seeing when using an ardunio for testing the GPS data out over UART.$GNGGA,011112.00,3214.62073,N,0580...
I've got some code working from an example for USART RX DMA Circular. I'm to the point where I can receive the UART data but I need to now use a write to a protected (by a binary semaphore) circular buffer from the interrupt context HAL_UARTEx_RxEve...
Hi,I've seen that in many stm32 tutorials (such as blinking LED and uart tutorials) they make use of a "while (1) " loop located in main.c: But, in the main.c generated by cubeMX for my stm32l496ag board i have only the following single while loop, ...

We have STM32F401VET6 in our product development. Currently, our project (makefile) compiles and stores application binary in STM MCU internal flash. We would like to store three other binary/hex files to the STM MCU internal flash as part of the bui...
Hi guys I have set up my STM32 as an SPI full duplex slave device. All SPI communication happens through DMA. The Master device is a Beaglebone Black communicating over linux spidev driver. The problem I am facing now is if the master sends multiple ...
Hello!As the title says, I haven't managed to get the printf function to work on my STM32H7 MCU. I am using the Nucleo-H745ZI-Q with STM32Cube MX and Keil. Here is the code I'm using:#include "stdio.h" /* USER CODE BEGIN 0 */ #ifdef __GNUC__ #defin...
I'm having a brain fart and can't figure this out. I'm porting an existing project from the STM32F205 series to the STM32L496 series. So I replaced "system_stmf2xx.c" with "system_stml4xx.c" in my project workspace, but my compiler (IAR) isn't pickin...
