15:08.34chouimatsjhill: "enjoying" it for about a week allready ... next week (around the 16) will be better ~18-22
15:08.51CosmicPenguinprpplague: tell me about it -you can't string us along for a week and then not give us details... :)
15:08.53prpplaguepretty warm here
15:09.05prpplagueCosmicPenguin: oh sorry didn't know you were alive
15:09.31sjhillcall him ZombiePenguin
15:09.32prpplagueCosmicPenguin: ok, so here's the deal, the lcd controler has a powerenable gpio for the lcd
15:09.45chouimatprpplague: and what is the humidity level?
15:09.51prpplagueCosmicPenguin: standard gpio style but controled by the lcd controler
15:10.25prpplagueCosmicPenguin: so this line on my board is feed to a inverter gate and then to the power for the lcd
15:10.36prpplagueCosmicPenguin: i.e. 0 turns on power, 1 turns off power
15:11.11prpplagueCosmicPenguin: so according to the sharp docs this is acceptable
15:11.24prpplagueCosmicPenguin: oh but wait.............
15:11.41prpplagueCosmicPenguin: burried deep within the pl110 tech ref manual...............
15:12.17prpplagueCosmicPenguin: and obscure note states that this when this power enable bit is 0, then ALL datalines for the lcd are held low
15:12.32prpplagueCosmicPenguin: and only when this is a 1 is when the data's are enabled
15:12.45CosmicPenguinheh
15:13.00prpplagueCosmicPenguin: freaking sharp
15:13.04CosmicPenguinSo in reality, they didn't need the inverter gate, then....
15:13.26prpplagueCosmicPenguin: yea, instead of a inverter just a buffer to handle the current
15:13.44ade|deskprpplague: invert the inverter?
15:13.47prpplagueCosmicPenguin: either that or change the mosfet switch
15:14.01prpplagueade|desk: yea, well, every part costs
15:14.29CosmicPenguininvert the inverter
15:14.29CosmicPenguinhah
15:15.49prpplagueman that was one of the most difficult debugging problems i've ever run across
15:15.52ade|deski guess it depends if you have spare inverter somewhere or a real buffer somewhere on the board
15:16.28prpplagueoh my pengium logo looks sooooooo good
15:16.38ade|desklol
15:26.51prpplagueCosmicPenguin: so you can see how bad this one was
15:27.03prpplagueCosmicPenguin: my code was fine, hardware+docs
15:27.31CosmicPenguinprpplague: see, you should always blame hardware.... :)
15:29.37CosmicPenguinThats what I do, and it made me the man I am today
15:30.00Crofton|laptopget the lcd working?
15:30.09prpplagueCrofton|laptop: yep
15:30.16Crofton|laptopgreat!
15:30.30prpplagueCosmicPenguin: well, my main problem in the whole deal was not really know how to best way to diagnose the problem

18:47.45prpplagueT0mW: hehe, not my fault though
18:47.53prpplagueT0mW: i did what the specs from sharp said to do
18:50.18T0mWprpplague: so, it was the power down bit, eh?
18:52.27T0mWprpplague: I dragged out the LPD LH79520 kit last night, dusted it off and dug up the schematics to the DSTN color LCD interface I had wired.
18:52.52prpplagueT0mW: sorta, it wasn't really listed as a powerdown bit
18:53.11T0mWprpplague: what'd they call it?
18:53.13prpplagueT0mW: thats kinda the whole problem, as you don't have to use the lcd controller based power control
18:53.54prpplagueT0mW: its listed a LCDEN bit
18:53.57T0mWIf you don't turn off the display, only drop power to the backlight, you get a "ghost" on the screen
18:54.21T0mWlooks funny
18:54.37prpplagueT0mW: but the whole point is that this function isn't bein gused
18:54.41prpplagueT0mW: yea i know
18:54.55T0mWprpplague: well, at least the scope gave you a clue as to what was wrong: nothing coming out the data lines. heh
18:55.26T0mWprpplague: ah! So, the electronics is not wired, but the bit defaults to "OFF" ?
18:56.06prpplagueT0mW: yea, nothing on the pin that it relates to
18:56.17prpplagueT0mW: so why bother messing with it
18:56.26T0mWboo!, hisss!
18:56.40prpplagueT0mW: there was absolutly nothing in the sharp docs that says that it controls the data lines
18:56.52prpplagueT0mW: not one word
18:57.08T0mWheh
18:57.12prpplagueT0mW: and ARM/primecell isn't much better
18:57.37prpplagueT0mW: the reference for the data lines is burried in a little font totally in the wrong place
18:57.54prpplagueT0mW: i'd have never found it unless i'd been doing word searches in the pdf
18:58.14T0mWtrouble is when engineers do documentation, they assume a certain level of understanding of the subject material.  Unless you have been steeped in this, the trivia will trip you up.
18:58.50T0mWfor example, the color pallete
18:58.58T0mWpalette ?
18:59.18T0mWI read that stuff and my eyes glaze over
19:00.17prpplagueT0mW: hehe, whyis that?
19:00.27prpplagueT0mW: i have more trouble with the timing
19:01.50prpplagueT0mW: well the fact that this bit _also_ controled something other than what was listed, is a pretty big problem in my book
19:02.18prpplagueT0mW: when describing a register you should list _everything_ that it effects

19:51.37CosmicPenguinjust brush up against some of the pins
19:51.41CosmicPenguinthat hurt
19:54.42prpplaguehmmmmmm
19:54.45prpplagueCosmicPenguin: get this
19:55.43prpplagueCosmicPenguin: vt1 is ok , i do a chvt 2, vt2 is ok, chvt 1, now vt1 is shifted about 4 pixels to the left, chvt 2, now vt 2 is shiefted about 4 pixels to the right

20:02.16prpplagueanyone got a clue whats causing that?
20:02.34prpplagueCosmicPenguin: you think its actually in the console driver?
20:03.34CosmicPenguinoh, thats right - you're not acelerating
20:03.41CosmicPenguinbut you are handling the _switch() function, right?

20:29.50CosmicPenguina 4 pixel shift would indicate that you might be off by a word somewhere
20:30.20CosmicPenguinor that your pitch is not right
20:30.32CosmicPenguinor that you're not reseting the offset
