Hi, I bought Myke Predko's "Programming and Customizing PIC Micro Microcontrollers." I'm using the El Cheapo board, software and MPLAB 6.1. I tried the "ledon" experiment and it worked with a 16F84A, then I tried a 16F877, it programmed and verified OK but when I put it in the circuit the LED turned on and stayed on regardless or input. I tried the home built version of el cheapo and got the same results. I saw some posts about Low Voltage Programming mode (LVP) and tried a 10K from RB3 to ground but got the same results. Has anyone gotten the el cheapo to work with the 16F877? Thank you, Bill __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
