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...

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...

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 - ...

Sweet, I'll give it a go, cheers. :)

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...

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 ...

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 ...

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. :)

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...

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...

Martino, I am able to write to the data buffer at addess 0x50. Then when i try to read from 0x51, I am unsuccessful. I am a little stumped. I write to 0x50 the following 0xFE 0x7A Next I read from data buffer doing the following: 0x51 (read 1 byte) (read 1 byte) (read 1 byte) etc... The response is...

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.

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 ...

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.

Hi, Just wondering if there is an error in the manual for the GLK12232-25? Pg18 shows a table for the expected response for a keypad press across the rows and columns: C1 C2 C3 C4 C5 R1 A B C D E R2 F G H I J R3 K L M N O R4 P Q R S T R5 U V W X Y But, I am getting this result: C1 C2 C3 C4 C5 R1 A F...
