Re: Screen Locks Up

Hi Nick, Sounds like you're running the most recent release! Just a piece of advice just in case you aren't already, I suggest you continuously read the returns from the display. Every time a label or gauge is updated on screen, the GTT will generate a return message and place it in its return buffe...

Re: Screen Locks Up

Hi Nick,

I'm glad to hear you were able to fix the issue!

Out of curiosity, what GTT Designer build are you running? Also, are you using GTT2.5 labels and Gauges, or are you using Legacy GTT2.0 labels and gauges?

Cheers,
Daniel

Re: GTT43a I2C Bug

Hi iotexpert,

After talking to our firmware designer, it sounds like the GTT's processor is capable of clock stretching, but it has been firmware disabled. I'll see if we can provide you a beta firmware with clock stretching enabled to see if that helps the situation.

Cheers,

Re: I2C Stops Working

Hi Alan,

I'll do additional testing with a GTT running the most recent firmware release to see if I can brick the i2c port.

Cheers,
Daniel

Re: GTT43a I2C Bug

Hi iotexpert, I have set up a test bench similar to what you described and was unable to replicate the issue you've described. The GTT's processor is capable of clock stretching so that shouldn't be the cause of the issue. Did you have any scripts attached to your button or does your host process an...

Re: GTT43a I2C Bug

Hi iotexpert,

I'll take a look at the I2C bus and test this specific situation. I'll let you know what I find.

Cheers,

Re: GTT 2.5 Driver License

Hi iotexpert, Looks like you've found our github page. We'll be posting a lot more code on our github page in the upcoming months. Our code examples will be similar to the appnotes we make available on our support site and can help kick start development for new users. All of the code that we provid...

Re: Text Toggle Button

Hi Alan, I apologize for the delay! 1. You are correct, 250 objects are part of a new protocol. At the moment, we haven't officially released any documentation about the GTT25 protocol. That said, when working in the GTT designer, you can press the Report button after generating/deploying your proje...

Re: I2C Stops Working

Hi Alan,

Have you changed the GTT's i2c address at all? Also, are pull-ups present on both the SCL and SDA line?

Cheers,

Re: I2C Read with GTT43

Hi Alan, Once the return buffer is full, the GTT will not be able to continue operating until it's data is read. It will wait until there is more space in the return buffer before executing any more commands. This is to prevent data loss, and ensures that all events registered by the GTT are reporte...

Re: I2C Stops Working

Hi iotexpert,

Are you unable to read and write data to the display at all? When a clear screen command (254 88) is sent to the GTT, does it respond at all?

Cheers,

Re: I2C Read with GTT43

Hi Alan, I'm glad to hear you're able to properly read all of your commands via I2C now. At the moment, there is no way to know how many bytes are in the GTT's return buffer, nor is there a single command to clear the buffer. The buffer will only house complete responses, so you can run a parser loo...

Re: I2C Read with GTT43

Hi iotexpert, Thanks for the added details about your project. Designing your project in the GTT Designer won't prevent the use of any GTT Commands. The GTT Designer Suite simply converts your screens into scripts and images, and uploads those files to the GTT. Upon boot, the GTT will start executin...

Re: GTT Design: Arduino Thermometer

Hi Everyone! I just wanted to let you know we've updated the demo and implemented user controlled temperature limits. The user will be able to set low temperature and high temperature limits and an audible alert will be triggered if the temperature exceeds either of those limits. Our stage 2 demonst...
