An open USB device driver for the StellarNet EPP2000 series of spectrometers
License: BSD 3-Clause "New" or "Revised" License
Estrella device driver for the StellarNet EPP2000 series of spectrometers. This driver is implemented as a userspace library on top of libusb. It has been written with Linux as a target OS in mind but porting to any libusb supported platform should be easy. If it takes any effort at all. A native Linux kernel driver implementation is also available by now but it does not offer all the nifty features present in the estrella user space implementation (e.g. averaging accross multiple scans). Estrella can only handle USB devices at the moment but should be easily extensible to drive IEEE-1284 connected equipment. For documentation have a look at the 'doc' directory. The provided sample application in 'test' should give you a pretty good idea of how things work. The driver API resembles the semantics of the windows version quite closely, you should feel right at home. Installation instructions can be found in INSTALL.txt.
First of all thanks for for this project.
We want to transition from using a PC with LabView to control our StellarNet EPP2000
with a RaspberryPi for students to do remote experiments.
Only Problem is that our USB2EPP
adapter from StellarNet has some hardware problems and StellarNet doesn't sell them anymore.
So I was wandering if any of you (@shugaa @kstenio) still uses the original USB2EPP
adapter or if you found a compatible adapter.
Another option for us would be to use this hat for the RaspberryPi and directly talk via IEEE-1284
but I can't find the spec files for the protocol.
How did you manage to write the usb driver?
Did you reverse engineer it?
Or do you know where to get the protocol specs?
Thanks a lot in advance.
