Hi everyone, I've done these steps before on STM32F0, STM32F1 and STM32F4 microcontrollers to detect when a circular DMA buffer for UART "wraps" (The counter finishes with the array and starts from the beginning again) with complete successActivated ...
Hello,I am verifying timer functionality on an STM32F303K8 Nucleo development board. After generating an update event, the counter register does not update immediately - in downcounting mode, it takes several nops for the counter to read the same as ...
If DFSDM uses internal parallel data input, such as direct write to input register or DMA writing, what is the maximum frequency of input data in this application?
Originally, I configured PB6 to work with OneWire using DMA! However, after some time, I need to use the same pin for operating an LED!Below are the steps to reset the pin settings to default.1. Stopping all processes associated with using DMA on pin...
Posted on November 21, 2014 at 19:59 I'm having problems reading the state of a GPIO pin. If I use the HAL function to read the pin, it always returns that the pin is high. But if I read it manually, then it works properly and co...
Hello,There are 8 revisions of the STM32F205: 'Y', 'X', '1', 'V', '2', '3', '4' and '5'.The silicon errata shows the status of support for all revisions, with no mention of individual revisions.Does this mean that all revisions are the same?Is it cor...
I am testing doing flash erase while running code from internal SRAM on a STM32F072B Discovery Board. Having initializing everything with code running in flash, I call a function where itself and all its dependencies exist in RAM. I've verified this ...
Hey, I would like to a string from terminal via UART in order to complete a challange given by Digi-Key YouTube channel in FreeRTOS tutorial playlist. Anyway, I want to take the whole string given by user in terminal, but I couldn't so far. I tried ...
Hello all, I was trying to follow the example in MOOC - STM32H72x/3x hands-on workshop - 6 Code execution from external FLASHI have configured the OSPI as per the board requirements in CubeMX. But the `OSPI_Init()` function fails while trying to read...
Hey,after trying to setup a different PIN for example: PC0 for PWM I just can not get it to work.But this sample code works only for PA5: #include "stm32f3xx.h" int main(void) { RCC->AHBENR |= RCC_AHBENR_GPIOAEN; RCC->APB1ENR |= RCC_APB1ENR_TIM2E...
