UART Transmitting issue or any other issue Hi Everyone,
I am using STM32F407DISCO board and made a simple program which transmit some values. The program is as follows
#include "stm32f4xx_hal.h"
#include "main.h"
UART_HandleTypeDef USART2Config;
void GPIO_Init(void);
void UART2_Init(void);
void Err_Handle(void);
char data[] = "Hello";
uint8_t value = 43;
uint16_t value2 = 1024;
char buffer[10];
int main(){
HAL_Init();
GPIO_Init();
UART2_Init();
HAL_GPIO_WritePin(GPIOD, RED_LED, 1);
HAL_GPIO_WritePin(GPIOD, GREEN_LED, 1);
HAL_GPIO_WritePin(GPIOD, ORANGE_LED, 1);
HAL_GPIO_WritePin(GPIOD, BLUE_LED, 1);
HAL_UART_Transmit(&USART2Config, (uint8_t*) data, strlen (data), HAL_MAX_DELAY);
HAL_UART_Transmit(&USART2Config, &value, 1, HAL_MAX_DELAY);
HAL_UART_Transmit(&USART2Config, (uint8_t*) &value2, sizeof(value2), HAL_MAX_DELAY);
while(1){
}
}
The code above only Transmit line 28 and 29, Line 30 not transmitted.
but when I comment out Line 28 then line 29 and
