Has anyone run MicroGUI (Rhombus) with a Javelin Stamp?

schiffli

I am having trouble setting up·some Javelin code which works with this application.· Has anyone done this before?· I have the RS232 AppMod and have created the txUart and rxUart as Uarts for simplex communication using no handshaking.· I can get the green and both yellow lights on the MicroGUI window to function properly, BUT nothing ever changes as far as the number on the numeric display.· Any help would be greatly appreciated.

·I figured it out.· For the Javelin stamp, the Uarts need to be set up with Uart.dontInvert and the PC set up with the Half-Duplex unchecked (off). Now this works like a charm!
