Excuse me, how to gracefully and effectively change the TX pin "inversion" of usart3 during the operation of MCU program?In addition, can I ask questions in Chinese? Every question needs the cooperation of translation software. I'm afraid there will ...
Hello,we have UART based communication that cause crosstalk between RX and TX lines.It can't be fixed, so I'd like to solve it in SW.I'd like to temporarily disable/enable UART reception before/after sending on UART.I'm already putting DMA into Pause...
I would appreciate if someone could provide me with some tips about how to accomplish this in an optimal way.I want to generate a square signal in one pin, and exactly the double in other, both must be synchronized.My first approach was to use one ti...
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...
Working on uvison5 keil IDEWhen I start the first debug session I don't get any interrupts (BLE).Only after pressing the "Rst" button, and jumping back to .s file the ISRs work.What am I doing wrong?
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); ...
