Digispark LCD Shield

[Stefan]

So ...


I just put together my digispark LCD shield, loaded the sketch, hit upload and plugged in my Digispark. It seems to have uploaded fine but I still only get the row of black boxes at the top. I tried playing with the contrast to no avail.


Any suggestions?

This is generally a connection issue-


Does the screen blink about 5 seconds after plugging in the programmed Digispark?


Are you using stackable headers on the shield?

You may wish to search the forum.

Hey,


Thanks for the replies.


I am using stackable headers. The LCD does not blink after 5 seconds (the digispark LCD example is loaded onto the digispark). I have a modelB and have cut within the white rectangle with an exacto-knife. According to the pictures on the LCD shield wiki I have the cable in the correct way.


Hmmm

You may wish to look at this as well.

The stackable headers originally supplied are wider than the socket so bending them 60 deg helps.

Just tried that and it didnt help either. What I'll do is connect an LED to each pin through the stackable header and see if I am getting signal through each ...


But I'll leave that for another night

OK. So I checked that the signal was going through the headers. That wasn't an issue. While doing that however, I noticed that the LED was still turning on even though I had used an exacto knife to cut very deeply through the little white triangle. Instead I popped the LED off and now it works just fine


Might be worth noting on the Wiki to write a simple sketch to see if the LED comes on or not ...
