Send multiple byte (3x4byte variabel and 4x2byte variable) of binary data over UART with DMA

2021-11-07
I have 7 binary variable that I want to continously send to uart with the DMA.I do not want to use ascii format, I want to send binary data.If I use multiple DMA transmits in a row, just some are beeing send due to the fact, that when the second is t...

STM32F4 problem receiving 0xF8 over UART with HAL

2021-11-06
Hello I am trying to send hex values over UART with HAL_Transmitin the cubeIDE I do:HAL_UART_Transmit(&huart2,(0xF << 4) | (0x8), 1,10);However I receive in Hterm0xC5I cannot make sense over it. Sending text with " some text" works fineHAL_UART_Trans...

What is lighter on the processor? SPI with DMA or parallel data transmission to a TFT display?

2020-09-29
The task is to print measured data from sensors and actuators on a display. The display of the data should not interfear with the high frequency measurement or the overal processor tasks.STM32F4

Frequency counter miscalculates when overflow and input capture happen at the same time.

I am using a STM32F446re to detect rising edges, calculate the frequency and execute accordingly.I have two signals that need to be detected. So I use two Timers 3 and 4. My frequency ranges from 3Hz to 300 kHz so I need to use overflow detection.How...
