Re: [sigrok-devel] Very simple tests for libusbtmc

Hi List, hi Lisandro

Good to see that there is movement in the usbtmc topic. With the kernel
driver development I was very unhappy...

If you don't have a usbtmc device but a EZ-USB FX2 device you can use
the GECKO3COM firmware to play around.

Some years ago I wrote this firmware for our project, it handles all
the basic must have commands defined by usbtmc, ieee488.2 and scpi (so
it blinks an LED when you use the usbtmc identify controll command). 
It's based on the USRP firmware and is fully documented using doxygen.
It was tested mainly with the old external kernel driver written by a
agilent employee and it's proven to handle files larger than 4 GByte.

"GECKO3COM uses a USB standard class, USBTMC, this makes is easy to send
and receive data from the FPGA"
