As an update to my trouble shooting:
I can't think of a good way to hook up the resistor, but along that idea, I took a piece of 12gauge (maybe 10) bare copper wire, created a U shape and laid that across the bezel on three sides, from the bottom, around the right edge, then to the top. Laid the TS on top of this and it worked.
I am going to try and find a smaller wire and try that (or pound the 12gauge into a flat frame), possibly tonight if time permits. I'll also give Ron's suggestion a try at the same time. I was also thinking about an EM field, but not to much as that stuff is way over my head. BTW, the TS scan occurs every about every 10-20ms.
As for the GLCD hookup, Here is the pin arrangement. (I just noticed i put a 2620 in the above schematic, I am actually using a 4620)
Code:
Pin Connection
1 VSS 0v – Ground
2 VDD +5.0v – Supply voltage for logic
3 VO None – Supply voltage for driving LCD
4 RD PortC.2 - 8080 mode 1 = No operation 0 = Read
5 WR PortC.3 - 8080 mode 1 = No operation 0 = Write
6 A0 PortC.5 -
7-14 DB0-7 PortD - Data Bits
15 CS PortC.4 - Chip select, Active L
16 RES PortE.2 - Controller reset signal, Active L
17 VEE None - Negative voltage output
18 FGND 0v - Frame ground
19 DISPOFF +5.0v - Display L: No Display
20 WAIT None
Thanks for the help,
Steve
