I got the same 32x32 RGB display has Brad, And running it with a PicNDuino ment using lots of wires to control the display and it just looked untidy and not only that I wanted something where I could easily disconnect and assemble the display quickly, because connecting each wire from pin to pin surely takes awhile!.
So I've made a DIY pcb Convertor for the Display and PicNDuino board!..
Also while designing the board I wanted a way of powering up the PicNDuino from the same power supply as what is used to power up the Display, so the power line is connected to the 5v rail on the PicNDuino (note: that I'm using a Mains Regulated 5v power supply - so not to burn out the PicNDuino board). So if I wanted to hang the display somewhere, then it means I only needed to connect the power supply to the board and everything runs nicely..
Programming the PicNDuino is still easily done by connecting the USB to the PicNDuino, ive had no problems there..
The board connections are the same has the following Swordfish code:
Code: Select all
Dim RedData0 As PORTB.0
Dim RedData1 As PORTB.1
Dim GreenData0 As PORTB.2
Dim GreenData1 As PORTB.3
Dim BlueData0 As PORTB.4
Dim BlueData1 As PORTB.5
Dim Latch As PORTB.6
Dim OutputEnable As PORTB.7
Dim RowA As PORTC.0
Dim RowB As PORTC.1
Dim RowC As PORTC.2
Dim RowD As PORTC.3
Dim CLK As PORTC.4- Heres the pcb board after etching - its not perfect and one small repair had to be made to one trace.
