Hello ! I've been wondering how DMA works in UART. I've checked some codes for example HAL_UART_Transmit_DMA(). I know it is set to sned 8 bit to peripheral. But I wondered when DMA knows that UART sent 8 bit when it is TX DMA or recevied 8 bit when ...
I'm doing a project where I want to have a toy say audio clips when a button is pressed. Right now I'm trying to accomplish this with an STM32F407G-DISC1. I have a small speaker (16 ohms, 0.25 W) connected to my breadboard with the DAC OUT1 of the MC...
Hello Community,given is this circuit:Typically when I use external pullup circuitry for a signal I set the corresponding GPIO to "Open Drain" and no pullup/-down as the state of the line is defined externally.Flash_CSn is directly connected to PB4 o...
I.want to know the use of series resistance that is placed with STM32H750B-DK and External RAM , And also.with it's Dual Quad SPI interface.Is it possible to leave them as it is or it is compulsory to implement.
What is the best way to use sscanf with uint8_t?When I use: uint8_t x ; char* y = "23" ; sscanf ( y , "%hhu" , &x ) ;I stuck at: void HardFault_Handler(void) I found following workaround that works: uint16_t x1 ; uint8_t x2 ; const char* y ...
hi i would like to use uart1_printf_debug debugging on a serial terminal but error message "undefine reference to "uart1_printf_debug" what file to include except stdio.h?
Hello,I have a problem with canbus on nucleo-f103rb. When I start the debug the registers look like before.png. After a while its look like after.png. But i cannot send any data to peak pcan in both cases. Here my code;/* USER CODE BEGIN Header *//**...
is there a way to generate (and possibly also read)a pal composite video signal using stm32 nucleo board.I've ben googled but i've found only a library for ntsc modulation
Hi, I'm a relatively new programmer, attempting to program a "Bluepill" module, which has the STM32F103C8T6 microcontroller. I'd like to be able to quickly change the duty cycle on a PWM output, so that I can adjust the position of a servo motor as I...
Hi All, i'm quite new to the world of embedded and only recently moved off MCU's like the ESP32.I just bought a STM32 Nucleo board and when I went to use it with the cubeIDE I got the error "No ST-Link Device Connected". I installed the drivers STSW-...
