hi there,

my name is yarek, i’m from russia (southwest)

currently i live in west yorkshire

good news, i’m making a midibox too. (midbox64)

i’m making the case in school so it is simpler. i am in school myself (age 15)

I got a problem regarding LCD module

i have ripped it out from an old printer/fax and it is in good condition :slight_smile: i think it is a 2x16 but i’m not shure and i dont know which type it is. can someone help me with finding it’s type?

PS. sorry for my (ununderstandeble) writing, this is my first forum

Privet Yarek!

I’m sorry I can’t help you.

But I’ll also ask a question considering the lcd here.

What size lcd should I buy for the midibox64?

Is 16x2 enough or do I miss something with it? If it is not big enough, then what size is?

3

try to count the number of character on it.. very hard sometimes, but it’s possible… how many pins are there on it? and what’s the name of the cip on it?

hi

thankx for your reply

regrding duraka, u know on your design, how much info do u want to be displayed eg:

name:      value

menu      assign

count the letters and spaces,(in this case 16x2)

there are dot matrix displays (which do not have letter blocks) and they are good for graphics, they are usualy expencive. but u can draw on letter blocks as well.

i cannot count number of characters because it is not turned on (you might find if you press on calculator when it is on you can see the blocks but is it’s off, then i guess not) but i’m shure it is __x2 coz i’ve seen it working and i can tell you the number of pins it has:

16 but only 14 were in use. on the chip seyed:

vhc16100

nrb 99-16w

jh-99016

and around it was: PM1610-4 PO24 REV:A

From the model number we can see that it’s 16x1. I think so.

thanks

i’m not worried that much about character length but the type as in can i use it for my midibox?

Hi,

if this is a graphical display with an unknown controller it will be very very hard to get it working. You possibly need to program your own MIOS LCD driver, and this requires a good datasheet which contains at least the pinning and the commands that are necessary for the initialization. Ok, and it requires some programming skills (you will find some driver examples in the MIOS download section).

If this is a 16x100 dot display, it would be sufficient for a common MIOS application. The character size is 6x8 pixels by default, this means that 16x2 characters can be displayed w/o problems.

Best Regards, Thorsten.

thanx

my display is not graphical.

how can i know if it ihas backlight

can i check it with my multemiter?

is there some special pins to look for?

thank you in reserve

Maybe the 2 remaining pins? You should definitely search for a datasheet before destroying the LCD.

Best Regards, Thorsten.

hi

i was looking through datasheets and i didnt find anything on my particular display, thay all were dot matrix ones. how do you find the right datasheet?

i still dont know my LCD type so its pretty useless !?

i am totaly lost. i dont have anough funds nor time for my midibox and i’m thinking of the worst thing… selling it  :'(
