Add LPUART Driver

Pin Define

1. Go to MCU pin define page

2. Search which pin can implement to UART

3. Define UART TX RX pin

4. Generate the code

Configuring Driver

1. Go to Driver page

2. Select new driver

UART Driver

Interrupt Driver

After importing the driver, it will be displayed under the driver layer.

Configuring Driver Parameter

UART Config

UartGlobalConfig: Configure basic UART parameters, including UART channel, baud rate, data bits, stop bits, parity, and flow control.

GeneralConfiguration: Generate a UART callback function.

Interrupt Config

Interrupt Controler: Generate a UART Interrupt handler

Source Code

Include

#include "Lpuart_Uart_Ip.h"
#include "Lpuart_Uart_Ip_Irq.h"
#include "IntCtrl_Ip.h"

Callback Function

void UART_ISR(const uint8 HwInstance, const Lpuart_Uart_Ip_EventType Event, void *UserData)
{
    if(HwInstance == LPUART_UART_IP_INSTANCE_USING_0)
    {
    	switch(Event){
    	case LPUART_UART_IP_EVENT_RX_FULL:

    		break;
    	case LPUART_UART_IP_EVENT_TX_EMPTY:

    		break;
    	case LPUART_UART_IP_EVENT_END_TRANSFER:

    		break;
    	case LPUART_UART_IP_EVENT_ERROR:

    		break;
    	//case LPUART_UART_IP_EVENT_IDLE_STATE:

    		//break;
    	default:
    		break;
    	}
    }
}

Init Function

void INIT_UART()
{
    Lpuart_Uart_Ip_Init(LPUART_UART_IP_INSTANCE_USING_0, &Lpuart_Uart_Ip_xHwConfigPB_0);
    Lpuart_Uart_Ip_SyncSend(LPUART_UART_IP_INSTANCE_USING_0, (const uint8 *)WELCOME_MSG_1, strlen(WELCOME_MSG_1), 65535);
    Lpuart_Uart_Ip_AsyncReceive(LPUART_UART_IP_INSTANCE_USING_0, rxBuffer, 1);
}
