New C30 page, now with automated goodness

by matt on Mar.21, 2010, under Informational

I have just created a new page to put all my C30 related tutorials, etc. on. It can be found at http://www.electricrock.co.nz/blog/microchip-c30/.

The most notable update is that my previous C30 building tutorials are now deprecated in favor of a new bash script that does it automagically. Check out the page for more details.

DLP-RFID1 library for Linux

Ensoniq Control 16 RJ-45 Connector Pinout

Optrex DMF-50573NB-FW Datasheet

by matt on Aug.23, 2009, under Informational

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 :) .
