DigiUSB monitor issue on RaspPi

[barbudor]

Hello

I am trying to use Digispark & DigiUSB with my RasPi running on an up-to-date raspian.

I've successfully uploaded a blink with digiusb sketch (see attachment) from my Arduino IDE on Win7.
It works fine with monitor.exe on the PC (see screenshot).


No I switch the spark to the RPi where I've been able to compile successfully the "monitor" tool (digiusb.cpp). Spark gets enumerated fine.
But when running digiusb, the display gets wrong as I see a bunch of strange character to be displayed on the input line (see other screenshot).


I get similar behavior whereas I run digiusb in Putty, MobaXterm (ssh terminal) or LXterm.

I have no idea if the problem is more related with curses/term settings or with USB communication.

Any idea where I could look ?

Thanks in advance.

You could try installing ruby 2.0 or 2.1 and the digiusb gem - it comes with a digiusb terminal emulator which I know for sure works on raspbian, as well as a ruby library you can use to access a digiusb device just like you would a serial device.

Hi Bluebie

Thansk for your answer but what is "digiusb gem" ?
I can't see anything like this in the raspian repository.
Where should I get it ?

Is that a digiusb terminal written in Ruby ?

For sure I will try this but I really would like to understand why the digiusb terminal I compiled doesn't work. Did I made a mistake in the compilation ? a problem when configuring the terminal ?
Also because at some point I may have to write my own C/C++ code that will talk to the Spark so I want to understand how to make it work.
I already tried to simplify the code to remove ncurses and just display the messages from the Spark, but nothing happen. Need to digg further.

Cheers

Install ruby on your rpi with apt-get, then run 'gem install digiusb'.
