Description

Alphacool lcd
Alphacool lcd back
The PCB is currently finished an awaiting delivery from Seeed Studio for a humungus price of $32.50
To the right you can find an image of the board itself.
LCD board

On the LCD board there was already an atmega chip present. If you connect something to the LCD pins directly, you get wierd random shit or just the code residing on the atmega chip that was present on the LCD. You MUST remove this chip to connect an external source for your display in order for it to work.

Check TRAC for more information and the complete working source for this project.

Parts

Parts needed for PCB

  • Alphacool LCD Display
  • Micro-controller: ATMega 2560
  • Network-controller: ENC28J60
  • Crystal for Micro-controller: 16Mhz
  • Crystal for Network-controller 25Mhz
  • Network connector: J1011F21P (has embedded magnetics)
  • 3.3 volt regulator: LM117
  • several capacitors and resistors
  • 2 pinheaders (2x3 & 2x10)
  • Jack connector for 5v power (required for the display)
  • Powersupply (or modified USB cable)

Parts removed from LCD

Next to the USB Connector on the back of the LCD is a small square microcontroller. This has to be removed before you can interface with the display.

Update

I have received the finished PCB
Finished PCB
and have placed the required components onto the pcb

(images can be seen to the right of this article)

Code

Currently i have the following code programmed into the microcontroller

Current state with above code

The last picture on the right shows the current status of the display with the above code

working display (sort of)

I am using a custom font on this display. Nokia_size6 This font is clear and reads perfectly from this display (if the display is working correct)
