In the data sheet you’ll find this table from which you can set the interrupt bits To enable interrupt change USART_RX_INT_OFF to USART_RX_INT_ON and then enable the peripheral interrupt.

But interrupts on the other way is the most efficient way to handle serial incoming data by a controller. Polling is something you will find everywhere so I’m not going to show here. Now to receive from serial pin you can do it 2 ways. UART1Config = USART_TX_INT_OFF & USART_RX_INT_OFF & USART_ASYNCH_MODE & USART_EIGHT_BIT & USART_BRGH_HIGH TRISCbits.RC6 = 0 // TX pin set as output TRISCbits.RC7 = 1 // RX pin set as input Unsigned char MsgFromPIC = " PIC Rocks\r " Unsigned char UART1Config = 0, baud = 0 #include " config.h " #include int i = 0 #define _XTAL_FREQ 8000000 // The speed of your internal(or)external oscillator #define USE_AND_MASKS #include Setting the RX and TX pins according to the table given above (you can find the table in the datasheet of the device you are using). So my settings is going to be: SPBRG = 51, BRGH = 1, A synchronous mode

My controller is running at 8MHz internal oscillator. Ok, so now I’m going to set my UART (asynchronous and high speed – BRGH = 1) to 9600bauds. Synchronous = Either TX or RX at a time – half duplex

What’s the difference between Asynchronous and Synchronous?Īsynchronous = Transmit (TX) and Receive (RX) can happen at same time – full duplex So first we need to set the speed/baud rate and here is the formula

Read this document for complete PIC (mid range) USART understanding: In order to know what’s going on inside the controller and how your firmware is behaving, serial port serves as a window to look into. Serial communication is one of the best debug tool ever when it comes to embedded systems.
