Hi,

I am working on a touchscreen USB project where I need to see the value of some variables, so I am trying to display this data on a parallel LCD display using LCDOUT. When the LCDOUT runs the USB communication dies; otherwise, the program runs flawless. I am using 10 ms polling and a pic18f4550. I use USBSERVICE right before and after the LCDOUT command but still the USB communication dies.

Yes, I know I can display this data in my pc using VB, but I am not there yet. Does anybody knows how long LCDOUT takes to execute and why the USB connection gets disconnected?

Thank you,

Robert
