Hi Kim,

I derived this library from other libs on this site, and as you'll see from this thread running under the RTOS has been talked about - and there are no known issues.

For my needs, I've got a few projects using the RTOS and this display library - but my larger problem has been in effective use of the RTOS; task stack frames, heap management, and the relative [in]ability to assess free memory.

Accepted Answer

Thanks Any suggestions about setting up the rtos for use with LCD lib Kim

As a small follow-on, one of my projects has a couple of threads, and I was unsure if I needed it, but I create a semaphore that the threads would take before sending commands to the display, releasing the sema when done.
