For use with DigiUSB library - see the DigiUSB->Echo sketch for an example of use. Monitor: GUI with a send and recieve box. Plug in your Digispark with DigiUSB first. Read and Write: Run Read to read from the Digispark Run Write to write to the Digispark You probably want to run both at once. Send and Receive: Send will send the first argument to the Digispark - example: send "This is a test" would send "This is a test" without the quotes to the Digispark and sending a newline character at the end Receive will recieve from the Digispark until a newline is reached and output all that it received These should help provide quick and dirty integration with other programs/scripts. Windows users should install the windows driver first. Released into public domain -Erik Kettenburg Python source requires libusb
