Homebuilt RS232 LCD Interface


Posted on Aug 18, 2012

There is enough of poorly constructed RS232 alike TTL level interfaces (+5volt) , this one generates it`s own +/- 10..11volts as RS232 specs. require , and is able to use very long cables like RS232 can , and protects computer as well , nice in funny environment like inside a `MP3 in car` setup. There is plenty of ready RS232-Lcd controllers 4 sale , at least 3 types I know about... Common to them all is that they are slow or does not have button support and/or are expensive... that`s my opinion
