This software will test the RC6 and RC7 as serial communication lines and produce square wave to all I/O pins. Square wave can be seen through oscilloscope or connect it to LED circuit or DTDT-I/O LED Logic Tester to see the LED blinking. - Trademark & Copyright - ♦ MPLAB IDE is copyright by Microchip Technology Incorporation.

Thank you for your trust in our products, if you found any difficulties, questions, or suggestions about this product, please contact our technical support at : [email protected] Copyright © 2008 Innovative Electronics Testing steps: - Set jumper J6 and J7 jumper and then RC6 and RC7 will serve as UART RS-232 serial communication lines (jumper connected). - Plug in serial cable to computer's COM port and RJ11 DT® PROTO 40 Pin PIC . - Plug in 9 VDC voltage source to VIN. - Run SERTEST.EXE. Select which COM port you are using and press Connect. Connect If you have been connected (no error message), press Serial Test. Test - If serial communication works well, you will see that sent/received data in the list is the same value ( send = 0, receive = 0, send = 1, receive = 1, send = 2, receive = 2, and so on) and a pop up window with “Serial test OK !” message. If serial communication does not work well, you will see that sent/received data is different value and a pop up window with “Serial test ERROR !” or “Communication timeout !” message.
