Posted on March 28, 2017 at 22:56Hello, I still tried with I2C on nucleo F401RE. I am use STM32CubeMx for generate files, but my program is not working. I want send three bytes on I2C in blovking mode. This is my code:
I2C not working, still is log. 0 on SDA and SCL. Please help me.
In rar. is all files.
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration----------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_I2C1_Init();
/* USER CODE BEGIN 2 */
/* USER CODE END 2 */
uint8_t buffer[3]={0x33,0x87,0X76};
while (1)
{
HAL_I2C_Master_Transmit(&hi2c1,0X40,buffer,3,10);
HAL_Delay(100);
HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_5);
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
