Both of our controllers, TC51553 and TC553/852, support a touch screen function. The only difference between TC51553 and TC553/852 controllers is that TC51553 supports Optrex F-51553 LCD only whereas TC553/852 supports either F-51553 or F-51852 LCDs.What are the differences between the TC51553 board and the T553/852 board? Is it that one does touchscreen and the other does not?
