For a hour I'm breaking my head. How it this possible? What's going here?unsigned max_prio = 5; __set_BASEPRI(max_prio); __DSB(); __ISB(); uint32_t basep = __get_BASEPRI(); printf("basepri=%u\n", basep); //>>>>>>>>>>>> it prints 0 ! Using the At...
I have an EXTI interrupt with a shared handler, EXTI15_10_IRQHandlerNormally there should be only pin 15 interrupt.So I did this:void EXTI15_10_IRQHandler(void) { if ((EXTI_D1->PR1 & (1<<15)) != 0) { my_handler(); EXTI_D1->PR1 = ...
Hi,Im trying to resurrect this project from 2015 (Software AWD control for RC Cards using 4x brushless motors):https://github.com/hammerfet/BrinirControllerIve built his VS2013 solution and got all that side working fine. However, next is to determin...
hi stm,i am using multiprocessor communication uart mode in STM32F303VC. i am not able to communicate UART2 at 312500 baud rate. i am using external oscillator of 10 MHz . please suggest what should be the clock setting for that.thanks,roushan
Can anyone from ST let me know when and if the STM32H7A3RIT (64-pin part) will be available. This is an important part that can be extremely useful in a large range of applications allowing much smaller form factor for the application than the parts...
HelloI am considering using STM32F769NI.Can all GPIO pins measure analog voltage when set to input?Thank you.
Code found in the main.c and figure of the issue seen in PWM_scope_NOK.png.
Hello,A simple question make me confused. For example, this code with return 40 value for a 10-member array.#include <stdio.h> int buffer[10]; int main() { printf("Hello World %d \n\r",sizeof(buffer)); return 0; }For settings my DMA for sp...
The HAL_I2C_Transmit_IT() in the STM32H7 HAL respond incorrectly, when the I2C bus returns NAK. In case of NAK, the I2C error interrupt must be triggered immediately, but it is triggered few seconds later. This is wrong response. The attached zip fil...
Hi,I have a STM32L476RG board and I try to execute the following program, obtained from this web http://www.microdigitaled.com/ARM/STM_ARM/Code/Ver1/Chapter02/Program2-1.txt which is for a different Nucleo 64 board (STM32F446RE)/* p2_5.c Toggle Green...
