hi there all. i'm new forum, far got needed existing topics or coworkers.. right i'm in need of more experties on field of arduino/c , glcds.
so, problem lays in fact, have premade pcb board several non-color glcds of resolution 192x32 dot pixels, custom made these boards, manufacturer doesn't want cooperate info @ them.
the next problem these boards , lcds on them driven via shared network, using 8 data pins (d0 - d7) , 8 address pins (a0 a7).
data pins common displays , other components, driven via hc373 ics, which selected via addressing on a4-a7. of these addressing combinations lcd enable pins (which r/w pin on lcd itself), while 1 of combinations openes "e6" connection d0, d1 , d2 lead lcd's cs, reset , a0 pins. (these latched, until next "e6" trigger last state saved! )
there's no actual "e" (enable) pin on module itself... (?)
i figured out of combinations, know write d pins onto displays, i'm struggling glcd itself. first of all, i'm not familiar glcds internal procedures in arduino ide, use arduino @ all, in such discovery phases, useful, used existing libraries until now. i have no idea how send instructions , later data arduino, connection uses common arduino pins lcds setup , data, therefore needs programatically controlled, no existing library in help.
since found 1 display such resolution on web, crystalfontz, decided try instruction set based on datasheet , hope work.
but, i'm stuck @ point how write instructions , data glcd module, without library, see/understand pins , data applied them , modify used shared network pcb works on...?
other that, have original controller of these lcds, reverse engineering of real pain...
i have schematics of board if of help, can post here, other that, if me out, i'd glad. point me out other info need, please.
cheers!
