Re: Can't deploy to flash card on GTT29A

Hi Pblase,

I have added your suggestion to the list of GTT Designer improvements. We'll be looking to implement encrypted file/directory compatibility sometime in the future.

Cheers,
Daniel

Re: Increment/Decrement Focus

Hi Pblase, Focus order on the GTT is determined by the object creation order. The object that is created/was dragged and dropped on screen first will be the first object in the focus order. At the moment, the best way to adjust focus order is to copy and paste objects to achieve the correct focus or...

Re: Can't deploy to flash card on GTT29A

Hi pblase,

Welcome to the forums!

Do you mind zipping up your project and sending it my way?

I can take a deeper look at the project here.

Cheers,
Dan

Re: Activate Motor & Activate Buzzer & Motor crash

Hi Dean, Activating both the motor and the buzzer at the same time causes a dramatic increase in current draw, which can cause the display to reset if not enough current is available. The GTT can draw as much as 650mA when the motor and buzzer are running simultaneously so I suggest that you double ...

Re: Load Font for otf files

Hi Dean,

We have been able to upload .otf font files to the display in the past, but if I recal correctly it would be on a font by font basis.

Could you provide the .otf file that you are working with?

Cheers,
Daniel

Re: GTT Firmware Rev 2.0 capabilities, protocol manual issues

Hi Dean,

That's great to hear.

I'll talk to Ray (Our software designer) to see if we can give you a pre-release firmware revision.

Re: I2C Read with GTT43

Hi Haz, My colleague and I have been testing your project to determine a solution, but our findings have been inconsistent based on the platform. When testing on a LPC microcontroller, there were no issues to be found. But when using an Arduino, we found that the program would hang after running the...

Re: GTT Firmware Rev 2.0 capabilities, protocol manual issues

Hi Dean,

The ability to create folders hasn't been released to the public just yet, but we will implement it in the next firmware revision release. Once the new firmware is released, I can provide an example on how to create your own folders and directories.

Cheers,

Re: GTT Firmware Rev 2.0 capabilities, protocol manual issues

Hi Dean,

Yes, the Length of data is an unsigned 16 bit value and the Index is an unsigned 32 bit value. You'll be able to upload data in 64K chunks so long as you keep track of the file index.

Cheers,
Daniel

Re: GLT24064R Firmware upgrade Failed

Hi Tim, It's unfortunate to hear that an error occurred during your attempt to update your display, and now your display has locked up and you are no longer able to properly detect the display using the Firmware upgrader, or through MOGD#. I'll provide a firmware file to you through email, and you c...

Re: I2C Read with GTT43

Hi Haz, I've built an environment that will continuously cycle through each of your screens and I have found something rather odd. My program will run one of your screen scripts, get the back light value, then transition to the next screen and repeat the process. I found my code was able to properly...

Re: Which color LCD is used

Hi Ritesh, For our coloured LCDs, the Liquid Crystal that's used doesn't change much, but the backlight and the LCD glass does. We can adjust the colour of the screen by changing both the backlight and the glass of the display. The standard Yellow-Grey LCD colour that is available on a lot of our pr...
