Propellent over IP

BigFoot

Does anyone know if it is possible to flash a Propeller chip over Ethernet ? or does Propellent just
scan the Com & Usb ports ?

Propellent just scans the COM ports which includes virtual COM ports like USB to serial adapters. There are Ethernet to serial adapters on the market. If one of them comes with an I/O driver that provides a virtual COM port, then Propellent will see that as well. Whether it's possible to program a Propeller over this sort of Ethernet link depends on the timing of the Ethernet connection and the way the I/O driver is written. The Propeller's download protocol is sensitive to the timing on the COM port and will timeout if the delays are too long.

You can't do this directly from the Propeller Tool since that sees only COM ports. It works with USB to serial adapters because these provide virtual COM ports. You can save the compiled program to a file, then use some other program to download the compiled program via Ethernet. Look at the Parallax Spinneret documentation. I know this works for certain with Adafruit's YBox2 and it should work with the Spinneret as well.

Thanks Mike, I was afraid of that.
