PostSubject: Led cube 5x5x5 programming problem   Sat Apr 04, 2009 8:07 am

Hi there

I recently finished my 5x5x5 cube. I am now having problems with programming it. The major problem is my programming knowledge Crying or Very sad . The original project http://courses.cit.cornell.edu/ee476/FinalProjects/s2008/pae26_rwc28/pae26_rwc28/index.html was made using a ATMEL32 chip. I have used in my project a PIC16F877 and I use PORTB for columns and PORTD for layers wich are the ground controls.

This what they used with ATMEL

// DDRC.0 = Decoder control bit 0 (LSB)
// DDRC.1 = Decoder control bit 1
// DDRC.2 = Decoder control bit 2
// DDRC.3 = Decoder control bit 3
// DDRC.4 = Decoder control bit 4 (MSB)
// DDRC.5 = 25th column
// DDRC.6 = Bit 0 of led ground
// DDRC.7 = Bit 1 of led ground

// DDRB.0 = Bit 2 of led ground
// DDRB.1 = Bit 3 of led ground
// DDRB.2 = Bit 4 of led ground

So with ATMEL PORTC is for columns and 2 of PORTC and PORTB for layers
And the original project has a accelerometer wich I don't have.

I have tried many times to make the code work on my PIC using MPLAB IDE v8.30 but no success. Someone told me that I should "port" the code but I don't know how.

I am desperate to make my cube work because I have worked so much on it. I have attached some important files (code and scheme + pics of the cube)

Can anyone please help me. Crying or Very sad

Have you had any experience with programming the PIC16F877, or any sort of microcontroller?

If you've had experience with programming this stuff, try starting off simple; like making the cube flash on and off, just to see if it works.
