Hi,

Do you have a component macro for controller graphics displays?

Also, I am going to buy a few LCD displays. I want to make sure that HD44780 16 x 2, 20 x 2 and 20 x 4 are supported by Flowocde component macro.

If YES, then is there a wiring diagram for how to wire this to PIC for Flowcode?

Thanks

Ron

Hello Ron

Currently there is no component for a graphical LCD.

However your other alphanumeric LCDs should all work correctly with Flowcode.

See this post for how to connect your LCD hardware.

Hi,

Link comes up with a 404 error.

Please double check, I hope the post is still available.

Thanks

Hi Ron,

I posted a question re this type of KSO107/8 controlled GLCDs on 11th Dec, as I had to get a demo up and running quickly at work, but I thought I was the only person who'd tried them as I got no replies. It's nice to see another person using flowcode using these panels. Anyway, I ploughed ahead and dived into the datasheet. I managed to get the display up and running without too much trouble. Don't think we are going to use these displays now as I think we going for something a bit bigger........

I am not a C programmer, and have a basic grasp of assembly (what the commands do, not actually programming in it mind!) but I got a 16F88 running it nicely, and a little bargraph showing a voltage via one of the ADC inputs. I have to say it is a bit fiddly to get to grips with as the display is made up two 64 by 64 blocks and you have to select which side of the screen you want to use. (not having a character generator makes life a bit less easy as well)

I looked on the web at general programming of these displays and was daunted as quite a few people said the timing was tricky and the datasheets were not much help to them as they contained timing errors. I found using Flowcode the timing was fairly non critical, and the display powers up quite nicely.

Anyway, hope you get your screen up and running, good luck

Hello Dan and Ron

I have looked at getting one of these displays to try to integrate it into Flowcode.

However I could not seem to source one. Could you give me a heads up of where I can find one in the UK,

Hi Ben.
I am very interested of using those displays in flowcode,i have posted some wishes to use those in flowcode3..
Dont know about where to get those in UK,i have get mine in ebay,seller called sureelectronic,those are quite cheap for him,and the shipping in worked wery well,shipping time about week in Finland... So if you are interested,look at ebay..
Hope you can find those,the glcd in flowcode would be really great..

Hi Benj,

We got ours from Braemac Ltd (http://www.Braemac.co.uk), who have supplied us with alphanumeric displays before.

Don't know what pricing will be like - (we buy alphanumerics in bulk) as we purchased ours as a sample.

Hope this helps

Dan

hello

you can olso try from Ebay there are many sellers for G lcd's

Hello

Ok thanks I've managed to get hold of some on Ebay now. Just awaiting the postage from America.

Hi,

Your previous post went like this:

1 - Ground - My unit Vss GOOD
2 - +5V - My unit Vdd GOOD
3 - Contrast pin (Centre tap from variable resistor with ends connected to +5V and Ground) - My unit V0 GOOD
4 - Flowcode specified RS bit - My unit RS GOOD
5 - Ground - My unit R/W
6 - Flowcode specified E bit - My unit E GOOD
7 - Not Connected - My unit D0
8 - Not Connected - My unit D1
9 - Not Connected - My unit D2
10 - Not Connected - My unit D3
11 - Flowcode specified D0 bit - My unit D4
12 - Flowcode specified D1 bit - My unit D5
13 - Flowcode specified D2 bit - My unit D6
14 - Flowcode specified D3 bit - My unit D7
15 - LED+
16 - LED-

Most of mine do not match..... Any ideas???

Thanks

Ron

Hello Ron

This topic is regarding a pixel based graphical display not the standard alphanumeric displays,

Hello Ben. Any news about ks107 in flowcode 3?

Hello Mikat

Yes I have managed to get hold of a few of these displays now. I just need to get some time organsied to complete the component code. If anyone has any code for these LCDs. Preferably in BoostC then it will greatly speed up the development time.

Looks from this that you are planning a component for the 168x 64 display. I have the opportunity to buy some of these cheap in anticipation so just need to check mine will be compatible. They are made by Displaytech and have either KS0713 or KS01088 drive ICs. Any idea if these will work the same as the KS0107?

Do you have plans for any other sized graphical display?

Hello Yes these should work fine.

We already have a 128 x 128 full colour display what other varieties of display were you thinking of?

Thinking of 128x64 monochrome display as can get them v cheap. Don't know what that colour one costs but will be 10 times the price.
