View Full Version : [SOLVED !] LCD interface for Proton Smart

5th January 2007, 14:09
Dear Sir,

Is it possible to interface a LCD to this Proton Smart?, My
need is I need to read SLE4442 card data and write information back to the
card and display this data on to the LCD, need to trigger a relay. Is this
can be programmed on this terminal if I get the source code sample and
compiler?. Is RS232 is used for programming?

Best Regards,
Premjo Elias
