A serial port JSON websocket server for Windows, Mac, Linux, Raspberry Pi, or BeagleBone Black that lets you communicate with your serial port from a web application. This enables web apps to be written that can communicate with your local serial device such as an Arduino, CNC controller, or any device that communicates over the serial port.

Serial port hits EOF randomly during run #62

Open capaulson opened 7 years ago

capaulson commented 7 years ago

I haven't been able to run a single reliability.

My hardware is a tinyg g2 running on a Due (latest version from master). The board is powered with an external supply, has a 100uF cap on Vin and is connected with a short USB cable (2ft) to a MacBook pro. The board is in a shielded box driving a Gecko G540. The spindle drive electronics are ~2-3ft away.

I'm running Version:1.94. The output of -v when the code fails is: 

2017/04/30 11:33:42 serialport.go:187: Hit end of file on serial port
2017/04/30 11:33:42 serialport.go:193: EOF
2017/04/30 11:33:42 serial.go:141: Unregistering a port: /dev/cu.usbmodem1421
2017/04/30 11:33:42 serialport.go:363: Shutting down writer on /dev/cu.usbmodem1421
2017/04/30 11:33:42 serialport.go:257: writerBuffered just got closed. make sure you make a new one. port:/dev/cu.usbmodem1421

Any thoughts on why the serial port is crashing?

First line of your debug indicates your USB connection is dropping and thus your serial port is disappearing. It indicates this is hardware issue on your end, not software.
