banneduser Posted October 13, 2002 Posted October 13, 2002 I chechked every pins, and they all connect to where they should ... ???Please,HELP. How to solve?
TK. Posted October 14, 2002 Posted October 14, 2002 Does the rest of the circuit work correctly? Does your computer receive any MIDI data? Did you adjust the contrast pot so that you see anything on the display after poweron?Best Regards, thorsten.
banneduser Posted October 16, 2002 Author Posted October 16, 2002 Everything else work fine except LCD. I can use every pot and do setup with vmidiboxplusThis LCD is what I got. It connect vdd with v0. Is that a problem?
TK. Posted October 17, 2002 Posted October 17, 2002 No, there is no direct connection between Vdd and V0, this is just only a line which indicates the voltage drop Vdd-v0.It would be interesting for me if you see *anything* on the LCD. Black rectangles or something else. To see those rectangles, you only have to connect Vdd, Vss and V0 and you have to adjust the contrast pot on v0.Best Regards, Thorsten.
