the pic dem lcd module it is completely ridiculous.
i had so many problems that i regret i bought it.
beside the fact that i still have unanswered issues from previous tickets, now i have a new problem again !!!
i needed to free some pins from lcd to use the additional functions on the pin, or as a digital i/o.
i moved the segments 12,16 and 17 to porth, segment 40, 41,and 42
i enabled the lcdse5 ,all the segments on the lcd configuration routine
lcdse5 = $ff
i made on the startup all pins on port h as outputs
trish = 00
The datasheet is confusing and say make them inputs, but the demo code said to be outputs
i remapped my display to fit the new segments location
symbol s13a = lcddata5.s40c0
symbol s13b = lcddata11.s40c1
symbol s13c = lcddata17.s40c2
symbol s13d = lcddata23.s40c3
and
symbol s16bc = lcddata17.s41c3
symbol s17a = lcddata23.s42c3
symbol s17b = lcddata17.s42c2
symbol s17c = lcddata11.s42c1
symbol s17d = lcddata5.s42c0
symbol s17e = lcddata5.s41c0
symbol s17f = lcddata17.s41c2
symbol s17g = lcddata11.s41c1
the display for this segments now is blank !!!
the project perfect with segments on seg12,16, and 17 , but not in the new loaction
it is no way that i can turn the segments on
I could'ev finish the project 3 weeks ago just using an holtek lcd driver, but i wanted an elegant solutions with one chip does all.
i think i was completely wrong.
Please help
Thank you
