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...
I've been having a few problems uploading code to that chip ( having to press reset every time in addition to the inability to use the "ST-Link (GDB server)" option for debugging) and i was wondering if that was due to the fact that it might be fake...

Hi Guys,I´m working with STM32F429ZI and I´d like integrate a project with json library. What is the best way? Are there ST json library? to STM32?Where can I find examples?Thanks,Geraldo.
Hi,I am using ST32F446RC.After jumping from bootloader to application, an fault occurs during clock setting(HAL_RCC_OscConfig function). The bootloader code and application code use the same clock code as below.static void SystemClock_Config(void) {...
