Im trying to make Nigels tut 1 work.
For some reason, It doesnt work unless i connect my scopes ground to the 5v transformer plugs negative connection!
If i connect the ground lead to the - wire, and then reconnect power to circuit,sure enough I get hello, etc..
If i disconnect the ground lead when its working, the screen stops drawing text, and all the text on screen dissapears.
Now If i reconnect the ground lead before resetting the pic, the screen corrupts.
Whats going on? Anyone have an ideas?
Many thanks.
