It doesnt work because I dont use the right bit configuration in my opinion.
Pic16F690 Serial Communication C Codes Serial Port AndA terminal program is a utility tool running on PC that helps you view text data coming from the serial port and also send data to the port.This is handy for initial development of connected hardwares.But now we also need to check if the data is able to reach the MCU from the PC or not. RealTerm will send those data to MCU and if MCU is able to read those data, it will reply back with the same character but enclosed in a. That means if you press a on keyboard you will see on the terminal window. Find the Port Named Prolific USB-to-Serial Comm Port and note the number shown next to it in brackets.

I downloaded your code, use the same setup ReakTerm and the same MCU, but I got all (0)zero in the expriment.

Can i loose some messages then As i understand it i must poll the USARTReadbyte() with a high frequency or am i wrong Best Regards Johan Nilsson. To over come this problem we need to write an ISR to handle USART events. As soon as data arrives USART jumps to this ISR which buffers the data in a FIFO queue. ![]() ![]() I am using Picdem.net2 board, have to configure usart as (9600 baud,8bits,No parity,1 stop bit ). Its working fine. But how to receive a string data using interrupt. Ive problem with timing, where data received, I stored it at buffer, but the moment I try to store data, I got another coming.and again.and again. I lost some of the data due to this routine. Do you have any idea how to solve string data received using interrupt. If you can give some code example, Im really appreciated.Thanks. I was wondering if you have come accross such a solution before. I have to transmit and receive data per EUSART2 of PIC18F46J50 and this although per INTERRUPT. Transmitting data per polling is although no problem, everithing is OK. But when I call the UART-Function Open2USARTExt() to initialize EUSART2 with USARTTXINTOFF the program function normally, but only with sending data without interrupt.
