Building a Graphic color LCD driver
Hallo all,
I'm in the planning to use a Graphic color lcd from EDT (type ET032001DH9). It uses a ili9320 graphic controllor.
This controllor is very easy to use i think together with a PIC18F4550.
Now i like to know of there are more people who like to have this kind of LCD display? Maby we can combine owr work to make it usefull.
When there are enough people that like to get this display. Then i can buy a big amound and create a nice small backboard for it so you get a nice interface posiblilty to you developers boards.
Let me know how you are thinking about this.

320x240 LCD Display using the ILI9320 Swordfish Driver
I'm currently working with the this display using the ILI9320 controller and I'm porting the C driver for the display this week. I'd be glad to share my results and like Steven said I'm a bit concerned about effectively driving/refreshing the graphics with a PIC18F4550 but I'll let you know once I have some test code.
Thanks Liger,
I'm still waiting on my display, so i can't tell how it will perform at the moment. But I know someone else has done it before, only with a other display but with the same controler. So i think, it can be done. You can find some pictures here on his site: http://www.techtoys.com.hk/index.html
There you can find also a libery for the iLi9320. Maby that helps.
Also i have the initialisation code for you when you like to have.
I will post you my steps later when i have recived my display.
PS. Liger, What do you use to setup the +/- 19,5 V for the backround LEDS?

I'm using the TechToys carrier board for the 2.4 LCD display and the carrier board has a built-in LED boost circuit.
I'm actually porting the ILI9320 driver provided with the display from C to Swordfish...
Are we doing exactly the same piece of work here?
If you already have init code for the 9320 would it be possible to share that code? I'll do the same once I get additional functions/features working with the driver.

Now i'm a bit confused, are you using my described lcd display from EDT or the one from TechToys? Beceuse the leds are connected differently. the once from grouped as 4 sets of leds and the One from EDT has one set of 6 leds.liger wrote:I'm using the TechToys carrier board for the 2.4 LCD display and the carrier board has a built-in LED boost circuit.
I have not started yet with coding for the display. I'm waiting on the delivery of it. I have just got a message that it will be shipped very soon.liger wrote:I'm actually porting the ILI9320 driver provided with the display from C to Swordfish...

My idea is to use the graphic lib's that already exist for SF and create a new controler libery.
What i have seen sofar is that the init code for the Displays are different for each display. So it is diffucult to create a general init procedure, i think.liger wrote:If you already have init code for the 9320 would it be possible to share that code?

The idea i have now is to create a Event call where the init code is putinto.
Does this make any sence?

I didn't quite read the first post...I was actually searching on the 9320 driver chip and found the thread. I'm using the TechToys carrier board which has a 2.4 LCD with the ILI9320. The good news IMO is that the 9320 driver is the key part to these so software that we develop for the EDT or TechToys carrier should be compatible.
I expect to do my first testing of the new code Thurs night. I'll keep you updated - please do the same.
BTW - where did you purchase the EDT display?

I've bought this display on eBay: http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0230587111
Thanks Matt,
This PDF is from an other display then i have.
btw this is the one i have: http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... 0290229980
