Your tutorials are very informative and helpful in my project. But am using a dumping kit in our lab. Though the code is being successfully dumped, the circuit is not producing the output even for the simple LED blinking program.

What could be the possible reason for it? Do we have to use only pickit3 for dumping? No you can use any kit to dumb the program. Are you sure the program is uploaded successfuy? Though my code is working partially with a scrolling message but instead of the characters to scroll from one display module to another, characters scroll on each individual display module Pls I dnt know if you can help me if I send d code C Lang and circuit..

I have used the same program. But the led is glows and never Blink. Did your simulation work? The circuit diagram and the table for the icsp connections are contradicting each other.

In the table pin 4 is connected to pin 40 while pin 5 is connected to pin 39 but in the circuit diagram pin 4 is connected to pin 39 while pin 5 is connected to pin Can you please clarify which one is correct.

Table is wrong, please follow the circuit diagram. Hi Guys,. Coming to my question you are using c language for programming and how does the delay is defined. It can be easily interfaced with any microcontroller using SPI communication mode. This diagram is not clear. Therefore, I provided a connections reference in the table below. These functions provides a definition of each soft SPI function such as initialization, SPI data transmit and receive functions.

These functions are used to send data from pic microcontroller to MAX using above define SPI communication library. This is a main function of the code.
