Posted: Thu May 03, 2007 1:19 am Post subject: What graphical LCD controllers work with BASCOM? |
|
|
Hi all...
I am looking to do a project that includes a touch screen graphical LCD. There is an ap note on one but the LCD is too small. I need one that is at least as large as a 12 key touchpad.
LEDSEE has one that uses a SED1335 controller - which although not color is pricey but large enough.
Can anyone suggest a different part and tell me which controllers interface easily with BASCOM?
Thank you!

bascom-avr only support 256x256 resolution, for example, 320x240 not supported, but 240x128 is supported.
chip T6963C for example is very easy. |

Any idea when Marc plans to support the larger resolution?
Any suggestions on a graphical LCD with touch screen that meets the largest supported resolution?
Thanks

Hi Tim,
Niels from Ledsee has added 2 touchscreen's today;
192x64 with an KS0108 controller and
240x128 with an T6963C.
Both controllers are supported by Bascom, so you can create very simple an touchscreen.
THIS is an 240x128 touchscreen that i have created in the past, and as you can see 12 buttons is no problem. |

Hello Evert
These displays look good, and cheap
The data sheet does not give details of the touchscreen, are these supplied when purchased or have you got them.
Cheers

How do i connect the 192x64, this display isn't supported by the compiler?
The driver only supports 2 Chip Select lines?
Or is this supported with an update of BASCOM-AVR and not mentioned in the Help-file?

Bascom supports several displays, but with proper documentation you can also write you own drivers. In the display-datasheets youŽll find all information - electrical and communication specs.
Usually you need a clock (CLK) and a data line. Also there is a select line to tell the display if a command (like contrast+ or invert) or data is being sent.
Sending the commands/data is done by SPIOUT or SHIFTOUT.
Displays with parallel datalines also work, you just need more pins.
I wrote a driver myself last month... for this display: http://www.pollin.de/shop/detail.php?pg=NQ==&a=NjY3OTc4OTk=
Since I started with ”C only a year ago, I would never have dreamed about being able to write the driver, but it works!
Again: if thereŽs a controller onboard with the display and you got a datasheet, it will be possible to use the display somehow. |

|

Hi all.
I used a 128x128 SED-controlled lcd display from Ledsee.com in a DDS controlled oscillator application. The display was introduced by Evert Dekker in AN #148. Although the display works perfect I finally found the 128x128 size was too small for my application. Therefore I bought the Ledsee 240x128 display:
http://ledsee.com/index.php?page=shop.product_details&flypage=shop.flypage&product_id=144&category_id=23&manufacturer_id=0&option=com_virtuemart&Itemid=27
Has anyone played with this display? They sell it as a T6963 controlled display but I detected T6A39/T6A40 line/row controllers on it instead of T6963. I'm not very familiar with programming lcd displays. Therefore I would be very thankful for any answer.
Thanks for helping.

Hi Rolf,
Have the same screen from Ledsee up and running here.
240x128 Touchscreen will work fine in Bascom with the T6963.
Code: |
Config Graphlcd = 240 * 128 , Dataport = Porta , Controlport = Portc , Ce = 3 , Cd = 0 , Wr = 2 , Rd = 1 , Reset = 4 , Fs = 5 , Mode = 6
|
For more information (schematic) check out THIS |

Hello Evert.
Thank you for the reply and all your information. Your info helped me very much. Your idea how to wire the touch-screen to the ADC is great. I use the display in a home made amateur radio transceiver - just one more building site... )
Regards
Rolf |

Hello everybody!
I am looking for 240x128 LCD, which will work with Bascom (so, no new lib to create...) AND will have negative yellow/orange/red illumination (that means: black display and yellow/... characters + graphic).
I check display from previous mail, but it's only avalible in "modern" white/blue combination. Well, I need something more "traditional" (will be built in wooden casing)... Does anybody have some suggestion where to look? I also checked www.lc-design.de (where I already ordered them several times), but their 240x128 LCDs have other controller + also wrong backlight color...
If there is such display that also has touchscreen, then I would be more than happy!!! (touchscreen is not 100% necessarry, but would be very useful to have it!)
Regards,
Gregor
p.s. I already programmed graphic LCDs with Toshiba T6963), but those were "only" 128x64 pixels... _________________ Programmer's life: When 1 bug is solved, another 3 appears... |

Looking at the pinout for the Ledsee touch screens, it appears 9 volts is required for LCD drive. Is there any way to power these screens with just 5 volts? |
