I bought a DLP-RFID1 USB RFID tag reader/writer from Digikey (Cat # 813-1013-ND). However, I was unable to locate sufficient libraries to develop software that uses it under Linux. So I have written a C++ library to do this. Read on for more information and to download it.

As I stated in my first Control 16 post, the C16 is meant to connect to a proprietary Ensoniq PCI card (which I don’t have.)  So instead I have been reverse engineering the C16 interface so that I can convert it for use with my PC.  The C16 has two connectors on the back a 1/4″ jack, which is used to connect an optional footswitch; and an RJ-45 connector, which is proprietary.  Both connectors are mounted on a board called PWR/SER_I/F.

I scored a few DMF-50573NB-FW 480×80 pixel graphic LCDs off trademe for $NZ5 each.  However, the documentation around on the internets for this particular variant of the Optrex DMF family seems to be sparse. So here is the information that I have gleaned from the looking at the devices themselves, datasheets for other LCDs in the family, probing with a multimeter and general experimentation. No guarantees as to the accuracy of this data, but so far it has worked for me.  If anyone has a datasheet please link in the comments .
