Charting

Hi, I have a design I am working on, and will be using the Chart object, with 1 to 3 lines on it. I have not decided to use the bar graph or lie on some. The reason for my post is to find out if there is a good example for the host side on how to interface with the chart object? I have 2 chart objec...

Re: Copying and Grouping Tools/Elements

I'd vote for that. There are a lot of GUI design features which should be considered. And I am not talking about functionality although that could use a boost of new features, but more like Align objects, copy and group as you mentioned, and more importantly, index similar objects with their ObjectI...

Re: UART

I did that because I only have one LCD. If you have multiple, you will need to make sure you save this into your structure returned so you know which UART to use to address it.

Re: UART

As I build up the project, I discovered some details which cause issues and I need help to figure them out. Here is my Display Setting Settings.png I have a script which runs after the SplashScreen is on and Echos 'x'. If you look at the protocol below, I see the 'x' which triggers my program to kno...

Ghost Touch

I am working with the 43A GTT, in UART mode. Everything works well, but I have a few questions. 1. What are the best practices for the images used on screens to make the startup time faster. Right now, I am looking at 3s (I have some graphics). If there is a way to modify the images to speed up, tha...

Re: UART

So I tried it and it worked: Here is the code. Obviously, someone will need to modify to fit their application MCU and compiler. I put an Echo command to execute as part of a script post loading of the first screen. Basically the display sends 0xFF when it is done initializing and I wait for that. I...

Re: UART

I will interrupt in the UART and notify the task to check the parser, that way, I am not doing anything in the ISR itself.

I will post what I get. I am in a debug mess on something else, but will get to it and let you know if anyone is interested in the future.
Thanks for the quick replies.

Re: UART

I am running freeRTOS. so unless there is something to do, the task is blocked. I can unblock it with a timer, but that would be a bit of a waste to just unblock to check and there is nothing there. That's why I was thinking about if there is anything which comes in the UART, then I know there is co...

Re: UART

Ok, got it working. Started over and got it working. It was a wiring issue. Which leads me to the next two questions: 1. With UART, do i need to poll, or can I just tie an interrupt to my UART, and the interrupt will call gtt_parser_process(gtt) everytime a char is received? 2. Is there a way I can ...

UART

Hi, I am trying to ge the LCDs to work with a UART connected to a MCU. I have the following LCD: GTT43A-TPC-BLM-B0-H1-CT-V5 GTT70A-TPC-BLM-B0-H1-CT-V5 I have it all setup and configured through the GTT Designer to be a Serial connection. This is the code: int uart_generic_read(gtt_device *device) { ...

Re: I2C Read with GTT43

Daniel, Just wanted to follow-up and see if you have made any progress. This is in my critical path for the project and I need to get it resolved, or at least a root cause so i can work around the specific case, and now jeopardize project functionality. It keeps locking up my whole project randomly,...

That's great that you were able to reproduce it.
Let me know how this progresses and i will duplicate any fix on my end.

Re: I2C Read with GTT43

Thank you Daniel, The get backlight is returning the right command, and the value expected. I do however need to send the set communication command after every screen, otherwise, my new loaded screen is not sending any of the button presses. If i add the command, then i start seeing the data coming....

Re: I2C Read with GTT43

Some more debugging: The code works completely if i add a 1 second delay after every screen load. And I have to call the gtt_set_default_channel(&gtt1, eChannel_I2C); after every screen load. Even if it is setup in GTT designer, I will probably have to add this to the Post load of each screen in...
