Here is my code for the serial interface. pretty simple... though i'm running into a few problems..

Sending commands... i have no clue nor can i remember how i did it before..

PROBLEM SOLVED

Woohoo, i can now control the display via 28x2, or via direct interface with visual basic applications which i create :D

Hey again >.< I have an issue with this segment display it is serial but all it does is flash really fast.

In the above image you can see the reset switch, the power and ground and rx to the atmega 7 seg display

the rx runs directly to pin 0 out on the 28x2 picaxe

In this image above you can see the wire-colors comming from the atmega 7 seg display

I know its very messy but i will improve

Got any tips on how to soder properly :( pressure/speed/ect?

it worked, i tryed it out and it works good at 5.1volts

Leave suggestions for my next circuit for 40x2 chip

i will be improving this 28x2 circuit :)

As you can see bellow i am in need of assistance to try and solve how to operate this display.

The componants i am using is:

1: PIC18F2520

2: Stereo Jack - For chip code download

3: DUAL COLOR 8X8 64 LED Matrix Display

-----------------------------------------------------------------------------

The problems im having is finding the right parts to operate this device

4: WHAT LED DRIVER SHOULD I USE?

5: WHAT SHIFT INVERTERS SHOULD I USE?

Hey as you can see the problem bellow is the resonator, you guessed it? i dunno where to put it or even know which pin is which.

As you can see it says it needs a resonator on pind 9 and 10, but its a 3 pin resonator which came with the chip, so how does it work?

pin 0v

pin 9 - resonator

pin10 - resonator

or

pin 9 - resonator

Hey all, ive just received quite a few componants tho i dont know what most of them do, i am learning about the datasheets of each peice that i have tho, i just need to know a few things and any support i can get to get this thing rolling...

Processors i have:

uM-FPU coprocessor (V2) // PICAXE-08M microcontroller // PICAXE-18X microcontroller //PICAXE 28X2 microcontroller

my goal is to interface with the program called "logicator" so i can see the code and learn from it and eventually code my own output

i have:
