STM32F469I-DISCO AU1 - Is USART3 disabled when LCD touchscreen is enable?
Hi.
#CASE1. After 2 weeks of intense learning. I am able to blink LEDs, push button with interrupt, able to communicate TX/RX with PC through USART3, USART6 (tried with both PC6/PC7 or PG14/PG9) using 3 different methods (blocking, interrupt, DMA).. (all these above are using CubeIDE)
#CASE2. BUT.. now i face new issues. I want to start GUI , so I create a new project with TouchGFX (with just a textbox), and configure MX same as the above. but... unable to communicate USART3 to the PC.
So I try to check is the different between CASE1 and CASE2. since both is using the same board. I see that Found that 1: MX_USB_HOST_Init(); was not present in CASE2. but i managed to enable it in .ioc
Found that 2: Clock configuration is very different.
Does clock configuration matters? What could be the problem?
Is it that USART3 cannot be used when LCD touchscreen is enable? I need answer for this. Please advise which USART port is available when LCD is enable.
void StartDefaultTask(void *argument)
{
/* init code for USB_HOST */
MX_USB_HOST_Init();
/* USER CODE BEGIN 5 */
/* Infinite loop */
for(;;)
{
HAL_GPIO_TogglePin(LED2_orange_GPIO_Port, LED2_orange_Pin);
HAL_UART_Transmit(&huart3, "HELLO ",5,10);
HAL_Delay(1000);
osDelay(100);
}
/* USER CODE END 5 */
}
