Hi. I want to OR two comparators to produce one fault signal to external device. While comparators on event are generating TIM1_BRK_UP_TRG_COM_IRQHandler and TIM1->SR & TIM_SR_BIF is set to 1 and my PWM output (which I use for debug) is stopped the ...
I have bought a new stm32f103c86 and I am trying to program it first time. To program the STM32 Blue Pill board I am using a using a USB to serial converter. The Rx and Tx pin of the Converter is connected to the A9 and A10 pin of the STM32 respect...
Hello,I'm having a problem after having changed the AHB Prescaler while the code was running...It did work for like 5 minutes then the problem appeared and I'm not able to do anything nowHere is the error :Contents mismatch at: 08000000H (Flash=00H R...
Dear,We using the STM32L071 and timer 2We will using a timer where the timer output is connected a relay. (watchdog functionality) The timer prescaler is set to a time of 2 sec. The output should be high when the timer counter is lower than the comp...
I'm using the EXTI1 interrupt and defined the EXTI1 handler like this:void EXTI1_IRQHandler(void) { __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_1); if (GPIOA->IDR & 0x0100 { EXTI->PR = 1; (void) EXTI->PR; NVIC_ClearPendingIRQ(EXTI0_IRQn); ...
I developing an application where I need to use 14 bit ADC sampling at 2 MS/s. This needs a fast ADC clock speed. I am using a V version chip that has a built-in /2 divider on the ADC clock. When I upgraded to STMCube FW V1-9.0 the other week, the c...
Hi,I'am reading data through USART1 and USART2. I am sending the data over USART3 using printf. It works for a while but then stops.Here is my code:FILE *stream; char *buf; size_t len; void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { if (...
I have found that from the ref. manual, certain bits of ADC control and configuration bits when ADC enabled but in the drivers provided by the ST showing that they are changing only when the ADC is disabled. For reference, I have attached the screens...
