I agree with Chris. Though the effort in the software has to account for something. I have 3 of the TIs when they were on sale even cheaper $7 as I recall. But that said. I have not had time to do anything with them. Nor half a dozen other things. So adding a display would be very reasonable. But the coding that is the real job. Regards Paul.
