Crypto71 Posted January 5, 2008 Report Share Posted January 5, 2008 Hi,nearly finished conversion of an old electric organ into a MIDI-device.My problem now is:I am using a LED 1602 module. The core display something readable (needs further testing as I do not know yet if all my DINs etc. work properly), but I cannot use P1 of the core module to dim or brighten the LED module. Simply nothing happens. I can set the contrast though. It works well.What am I missing here? What could be wrong?Thx for any hint,Crypto.
