USART1 doesn't work
Posted on February 11, 2018 at 15:00
Hello everyone. I have encountered problem with USART1 on STM32F446RE. It seems it doesn't work for me. I have used multiple times USART2 and it works as it should, but USART1 with same configurations just refuse to work. What could be the problem?
I use STM32CubeMX v4.24.0.
UART_HandleTypeDef huart1;
UART_HandleTypeDef huart2;void SystemClock_Config(void);
static void MX_GPIO_Init(void);static void MX_USART1_UART_Init(void);static void MX_USART2_UART_Init(void);int main(void)
{ HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_USART1_UART_Init(); MX_USART2_UART_Init(); while (1) { HAL_UART_Transmit_IT(&huart1, (uint8_t *)'Hello with USART1\r\n', strlen('Hello with USART1\r\n')); HAL_Delay(1000); HAL_UART_Transmit_IT(&huart2, (uint8_t *)'Hello with USART2\r\n', strlen('Hello with USART2\r\n'));}
}
static void MX_USART1_UART_Init(void)
{huart1.Instance = USART1;
huart1.Init.BaudRate = 115200; huart1.Init.WordLength = UART_WORDLENGTH_8B; huart1.Init.StopBits = UART_STOPBITS_1; huart1.Init.Parity = UART_PARITY_NONE; huart1.Init.Mode = UART_MODE_TX_RX; huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart1.Init.OverSampling = UART_OVERSAMPLING_16; if (HAL_UART_Init(&huart1) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }}
static void MX_USART2_UART_Init(void){huart2.Instance = USART2;
huart2.Init.BaudRate = 115200; huart2.Init.WordLength = UART_WORDLENGTH_8B; huart2.Init.StopBits = UART_STOPBITS_1; huart2.Init.Parity = UART_PARITY_NONE; huart2.Init.Mode = UART_MODE_TX_RX; huart2.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart2.Init.OverSampling = UART_OVERSAMPLING_16; if (HAL_UART_Init(&huart2) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }}
