Yes, that is a simple version of what I need. Thanks your sample is helpful
and gives me some additional ideas for how to do things. Using Chris's links
I've managed to create something that does almost everything that I need
although I still have to add a CRC calculation for the output messages
Those look useful so thanks!
I'm doing the software that receives the serial data so I should able to
read and process everything fast enough to not require flow control. Even if
I miss a message the next update message will be good enough. I'll probably
include a start of message and definitely
I am attempting to produce a Python component which periodically outputs
X/Y/Z/A coordinates via a serial port that is actually a USB connection.
This is similar to what is required for pendants that display the current
coordinates. Can anyone suggest a tutorial or source code that could be
Bingo!
As suggested by John, I tested a trivial program on an Arduino Leonardo
(ATmega32u4) that sets/unsets the UDCON bit0 every 20 seconds. PathPilot
sees/loses/sees/loses... the USB port every 20 seconds. I need to do more
testing but it appears that my problem is solved.
Thanks for
UDCON = UDCON & 0xFE;
The above compiles without error for an Arduino Leonardo. I'll try it in the
shop tomorrow.
Thanks!

You are correct. I have a udev rule to connect to my particular VID/PID. The
problem is trying to talk before I'm really ready.

Isn't DTR a signal controlled by the host (LinuxCNC) rather than the micro?

Hi Ken,
PJRC's version of Arduino is somewhat
Thanks for I'm unsure how that helps. My widget interfaces to
LinuxCNC/PathPilot as a serial device rather than as a mouse or keyboard.
What should my entry in udev/rules.d look like?

There are lots of reasons for such random failures but in my experience they
are often the result of over allocating RAM for data and thus leaving too
Your suggestion sounded great so I did a few tests. I loaded a PCJR Teensy
LC (ARM Cortex-M0+) and a genuine Arduinio Leonardo (ATmega32u4) with the
standard BLINK program -- the Arduino equivalent of the Linux HELLOWORLD.
For those unfamiliar with the Arduino world both of these boards have
