How to transmit UART data on STM32 discovery board?
Hi forum, I'm developing on the stm32f3disovery board with STM32F3-Discovery_FW_V1.1.0 running in IAR Embedded Workbench. I've been able to get the basic demo compiled and running, but I can't seem to get UART data transmission to work. There are no ...

Resolved! How to receive all data over UART interrupt?
I am using a STM32LO73RZ board. I have set up UART with interrupts and this works. I receive data that I send from an USB to TTL converter. When I sent a character one by one, this works fine. However, when I try to send a larger message, I keep miss...
Using Array to toggle outputs
Hi,I want to try use an array to set particulars outputs, base on values in that arraysI have initiated two dimensional array like in example below:uint8_t obrPr[4][4] = { {0,0,1,1}, {1,1,0,0}, {0,1,1,0}, {1,0,0,1} };This is sequences...

RXFD_MODE and TXFD_MODE pins, what are they for?
STM32H745 DS indicates there are these signals:CANFD1_TXFD_MODECANFD1_RXFD_MODECANFD2_TXFD_MODECANFD2_RXFD_MODENo mention is made in the DS for their purpose, nor in AN5348 "FDCAN peripheral on STM32 devices". The signals are not mentioned at all in...
Hello, I need help in setting up a SPI3 communication with AT45DB161E flash memory using STM32H743II. My application gets stuck when trying to write/read data to the flash and I don't know why. Details and code can be found below. Thank you!
More details on the topic:I have a working application that runs with nuttx and is able to successfully configure SPI3 and read/write to the flash memoryI have compared the registers between my app(that doesn't work) and the application that runs wit...
Resolved! How to send a single USART character under interrupt, on an STM32H743?
I have the following code, which is *almost* always working. (It typically gets stuck after 10-100K characters.)void USART3_IRQHandler(void) { if (LL_USART_IsActiveFlag_TXE(USART3)) { stats.txe++; if (LL_USART_IsEnabledIT_TXE(USART3)) { LL_US...
