Re: Animation speed

Hello, Thank you for posting on the forum. You are correct, a specified time of 1000 results to 20 second interval. And you are right, unfortunately the manual is missing information that each interval is 20ms. I wonder if you have used GTT Designer? https://www.matrixorbital.com/News/gtt-designer_...

Animation speed

The protocol documentation for the animation file states it is plain text file with lines of milliseconds followed by filename. (Though the the example hexadecimal screen dump doesn't match the text below which has "2" before every filename). I have a simple animation working with 2 images...

Re: No display found

I ran into this with a new Win10/AMD 64-bit install and was able to resolve it with Zadig. Posting this here as web searches lead to this thread. 1) Make sure the GTT is connected properly using the primary USB connector, not the alternate USB. 2) Install/Run Zadig. 3) Click Options -> List All Devi...

Re: GLK19264 Rev 2 Strip Chart

Raquel, Thank you the information. Fixing the endian resolved the primary issue. I did find that the chart will draw erratically if you set chart values far outside the minimum/maximum range so that should be avoided. I am seeing one more oddity that I cannot resolve in that strip charts will not re...

GLK19264 Rev 2 Strip Chart

Looking at the documentation for GLK19264 Rev 2 I see that the strip chart commands have been changed and the old command no longer available. My attempts to render strip charts using the newer commands produces bizarre results and the documentation of the parameters is practically non-existent. Wha...

Hardware based RS232 flow control?

Hello, Is it possible for the GLK to use RS232 hardware based flow control, meaning it will use RS232 hardware signals if it is ok to transmit? I have the software flow control implemented in that I send characters to the GLK one at a time while checking a "volatile" flag indicating if it ...

GLK19264-7T-1U returns incorrect size on download command

Hello, I have encountered what appears to a bug with the download command on the GLK19264-7T-1U. According to the documentation, the download command (0xFE, 0xB2), should return a 4 byte size followed by the bytes of the file, however whenever I use this command to first byte (MSB) of the size alway...
