I'm working on a VFD controller using an AVR, and also looking into using an Arduino. I seem to have found that the Arduino has problems working with the serial port because the Rx and Tx pins are also tied to the USB interface, the BootLoader, in someway the serial port monitor and debugging. It seems if one's application causes serial data to stream on power up, the BootLoader takes this as something trying to talk to the BootLoader and loops without a time-out. Unfortunately, one needs to use this link in order to edit the application to stop it from streaming until after the BootLoader does its thing and gets out of the way. There is a USB chip update that is supposed to fix this, but requires some command line gymnastics and something called DFU. I don't know what I did, but I finally got the update loaded and it seems to work now, but this brings up the thought, considering the importance of the serial port to many CNC applications and the serial port resource sharing on the Arduino, is Arduino appropriate for LinuxCNC applications?
