Lookie what I got! I've searched throughout the web and that lcd is worth 300 bux - I bought it for 25 bux at a local Electronic shop (surplus apparently, they've got 50 in stock). Only problem is I can't seem to find a datasheet for it. I don't even know what controller it has if any. It's a hitachi SP14Q001 320x240 (?). Does anybody have any information on this LCD? What software can run it? Or can it be interfaced to a parallel interface?
Thanx for the link the_shark!! Awww.. no built-in controlller? That sucks, I wanted to interface this to paralllel... When I was searching for the datasheet I stumbled across this site: http://hitachi-displays-eu.com/frames_products.html they didn't have datasheet for my lcd but they have datasheet for other models of SP14Qxxx - all models have the same pinouts and I found out that other models of this lcd has built-in T6963 controller! So, is it safe to say that if I can get a hold of a t6963c controller I can hook this thing up?
Man that is a sweet LCD. Does the shop that you got it from have any more? I am really interested in somthing like that. If the shop does not have any more is there any chance that you might want to sell it? I am studying electical engneering and I want an LCD like that for a project that I am working on. Does it have a back light?
They have 20 more. THe picture isn't mine, it's not my hand but it's exactly like my lcd.. The LCD has CCFL backlight and the electronic store i bought it from happened to have the inverter for it sold for 6 bux - so total around 31 bux. The site I got the pic from sells the exact same lcd for 255 british pounds!!! That's over 400 bux!! http://www.avolitesdownload.com/acatalog/spare_parts.html
My bad. I looked again and it doesn't look like it can be controlled via T6963c controller. However, it looks vaguely similar to a SED1330 compatible pinout: Pinout: 1 > D0 2 > D1 3 > D2 4 > D3 5 > Disp-Off (Reset?) 6 > Frame 7 > N.C (No Connection?) 8 > LOAD 9 > CP 10 > VDD (Power Supply +5V I think) 11 > VSS (Ground) 12 > VEE (Contrast?) 13 > V0 14 > VSS (Ground) I'm bidding on a sed1335 controller right now. I dont' know anything about PICs but I'm willing to give that a go if nothing else pops up - sounds really interesting. I've ordered samples of PIC16xxx, can I use this? Does anybody have a link to a guide or tutorial on interfacing something like my lcd to a pic (Besides Hazer's guide)? I've done some search and it looks like PIC16xxx is programmed with assembly (it's been decades since my last assembly class) - I'm more familiar with C/C++ so I'll probably have to go with PIC18xxx - what do I need to get this started??
that link takes me here: http://www.megas.org/megashop/de/index.html?d_20508_G_LCD_240x128_Weiss_auf_Schwarz__CCFL_1043.htm That doesn't look like a sed1335 controller.
Sorry, something wrong with the url, click on "G/LCDs" and you will see a SED1335 controller kit a little lower on the page... CD
you could probably do it on a 16xxxx seires PIC, but 18's can work at twice the speed, you will need a lot of IO pins as you will have to make an address + data bus for the memory, and an interface for the lpt port to control your controller, its not that difficult to make your own LCD controller, but you will need aditional RAM if your using a PIC, (heck even if you used an Atmel AVR). Check www.piclist.com i think i saw somthing similar to this on there a while ago.
I emailed the Hitachi sales department looking for a controller for this lcd. Here's the response I got: Dear Adonis, The SP14Q001 was discontinued a few years ago. We do not have the spec for that particular panel, but here are two specs which may be able to help you with what you need. As for your question about a controller, the panel has a timing controller on board, but the display controller is external to our panel. I hope this helps. Best regards, Jake Spengler East Coast Sales Manager Hitachi Electronic Devices (USA), Inc. ------------------ The attached documents were specs for the SP14q002 and 3 models. Very identical to the SP14q001 same pinouts as a matter of fact. What's a timing controller? I asked if the sed1335 controller was capable of running this lcd but he didn't answer.
Like I said in my previous post (or as you can find on the internet), there are several places where you can find a SED1335 (a T6963c controller board is difficult to find)) prebuilt controller board for your LCD if you not cannot make your own. CD
What about using rs232 interface? Is it difficult to make my own rs232 device based on the max232 chip? for that matter, can this get me started? http://www.sparkfun.com/shop/index.php?shop=1&cart=37956&cat=7&
rs232 is possible, but i would recomend making a parrallel interface first, to get the hang of it. You would have to do this in ASM, so don't be scared.
