Re: Separate region and coordinate response areas

Hi Daniel, Yeah I spotted the slider function, but didn't like the graphic :) It'd be good if you could implement different reporting styles for different regions in a future firmware update. Meanwhile, by getting the host micro to tell the LCD to change button images to show a button press, I'll be...

Separate region and coordinate response areas

Hi folks, Is there an easy way to do the following: Have four buttons that have a reporting style of RegionUpDown, and another area of the display where the reporting style is CoordMoveUpDown? At the moment, it seems I can only have one or the other. In my application, I have four buttons, and a sli...

Version 1.4.0.7878

Finally got around to playing with this new software tool, and first impressions are good. Suggestions: It would be nice if we could copy a whole group. For example, I created a whole bunch of LEDs, and made them a group. I then wanted to copy that group of LEDs for a second channel, but couldn't - ...

Toggle GPO ports

Hey folks, Is there a way to simply toggle a GPO via scripted region? Example: Press a button, set GPO port to high. Press same button again, set GPO port to low. Obviously, we can set a state to on or off as in the manual: 254 73 Number Setting But you can't use that same statement to change the po...

New GTT series

Hey guys, Just wanted to say, well done on the new GTT series! Although the GTT480272A was a great display, I didn't find it's touch response so good, unless I used a stylus or tip of a finger nail (even after a cal). But, the new GTT series is very responsive to the touch of a finger tip, and very ...

Portrait/Landscape mode, and scaling

Hi, Are there plans to introduce a portrait/landscape command? ie - rotate everything 90 degrees. Also, been having a quick look at scaling bitmaps - assume I can use the 9-slice feature for this? Basically, I want to be able to load a map of an area, zoom in and scale the zoomed in area to fit the ...

Re: Missing i2c.cfg file and manual confusion

Hi Henry,

Current prototypes - 2 of them, are using the older GTT480272A, but we will switch to the newer version for the next run.
I'll also be buying the 800 x 480 GTT, to try a few ideas out for other projects. :)

Re: I2C GLT to GTT

Hi Truby, I was getting the exact same problem as you, lots of 0xFF's. I figured out that it was because I was doing this: Start I2C send LCD read address read byte read byte read byte read byte read byte read byte Stop I2C The above is the wrong way to read multiple bytes. The correct way is: Start...

Re: I2C GLT to GTT

Actually, the algorithm above isn't quite correct. The main C code that calls Read_I2C_data() should be: //Get 6 bytes of data from the LCD - in this case Touch region events from a GTT a = 0; while (a < 6) { [tab=30]StartI2C(); [tab=30]Write_I2C_data(LCD_READ); [tab=30]SCL = FALSE; [tab=30]com_buff...

Re: I2C GLT to GTT

Re: Missing i2c.cfg file and manual confusion

Solved, regarding the I2C config issue. Just created a text file, with "00 80" in it, named it i2c.cfg, and threw it into the system folder. :)

Display now works.

Missing i2c.cfg file and manual confusion

Hi folks, I'm having some issues getting a GTT480272A going on I2C. I know my code works, as I've had other displays working on I2C. Looking in the System folder of the SD card, and the I2C.cfg file isn't there. Would the display just default to 0x50 if this file is missing? How do I get it back if ...

Re: GLK12232 Keypad - Rows/columns swapped?

I should have checked the revision on the PCB... it's rev 2.
That explains it. :)

Also confirms my C code for reading via I2C is working. :)

Thanks for the speedy reply.

GLK12232 Keypad - Rows/columns swapped?

Hi, Just wondering if there is an error in the manual for the GLK12232-25?
