Logik IR100 – DAB 608 LCD

So as Reciva has now closed, the Logik IR100 and other Reciva based radios will no longer work without installing Sharpfin and modifying it. Great, but I want a newer system with more hardware features and a powerful CPU… Step up Raspberry Pi.

However, as I am sure a lot of you have noticed – The LCD doesn’t conform to the HD44780U wiring scheme. Alas… I think I may have at least worked that one out and managed to get it working with an I2C backpack, though right now the backlight doesn’t seem to turn on.

Pinout for the display vs HD44780U

HD44780U   DAB 608 LCD 
3V0 (Contrast)—>4VA
7DB0—>9N/C – DB0
8DB1—>10N/C – DB1
9DB2—>11N/C – DB2
10DB3—>12N/C – DB3

  1. Thanks for the useful information. I am currently exchanging the reciva module with an ESP32 and reusing the main 608 PCB of the radio. The display is powered with VDD 5V. If you Power with lower voltage, then the backlight might not work. The backlight is controlled with the LED pin. I think the 608 PCB has some transistors to pull this pin to GND.
    My backlight is working, but I think it is in bad shape as the brightness is very low (The issue was already with the reciva module).

    1. This is great to know. I still haven’t got around to rebuilding mine with a raspberry pi yet but I shall check out those transistors and see if I can figure it out with my backpack!
