The past months I've been very busy trying to get the APSX RW-210 rfid reader to work with Arduino. I can now say it has been a total success!
The last piece of the puzzle was trying to compare tags to an array of tags living in PROGMEM. To do this I had to use the command "memcmp_P" which was only added to avr_libc version 1.4.6. I was able to replace parts of the Arduino avr lib by the new lib. It works perfectly and has enabled me to compare rfid tags to a list of more than 75 tags in flash memory! See my post for code and details: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1188236776/15
I was wondering if there are plans to add avr_libc 1.4.6 to Arduino 010 ?
