I'm trying to interface JHD 162A LCD display to a tiva c launchpad tm4c123 using Keil.

trying to read the busy flag, when i switch the port as input port, it becomes 0x80 means D7= 1 (busy), what should i do as it is not changing back to zero?
Should I use voltage converter to convert 3.3v to 5v?
I'm giving external 5v to lcd, should it be given using launchpad?

Can you give more details on the issue? – Mahendra Gunawardena Dec 23 '14 at 00:35
I think there is voltage incompatibility, I tried using opto-coupler, buffers but nothing seemed to work! – Niraj Jan 31 '15 at 09:46
