i am planning on buying a 3.2 inch tft for a project and it's even mentioned on LCD board that it works with arduino MEGA but i've read somewhere that it works on due too.
i know due is 32bit mcu but does that means that library for that LCD will work fine with due too or due have some other library?
can i use all other sensors like thermocouple and servo motor in 32bit mcu without needing any other library ?
does due have support like uno r3 does ?
Life with an Arduino is simpler if you buy a Display that is made into a Shield.
i.e. all the male pins line up and mate with female sockets on your Arduino.
You can fit a Uno shield onto a Uno, Mega, Due, Zero .or any conventional Arduino.
You can only fit a Mega shield onto a Mega or Due.
If you buy a Display with a 20x2 header, you need a 40-pin Adapter shield. There are several commercial products.
If you buy a Display with 17x2 header, you have to make your own adapter with level shifters.
Please post links to the displays you are thinking of purchasing.
Someone can tell you what other components you need to buy. (if any)
