I am trying to interface JHD204A LCD display with my FPGA board. The problem is that LCD works with only 5V power supply, and my FPGA supplies 3.3V only. I supplied power from another source of 5V, and connected the grounds of both togeteher. LCD display is showing bright light, but no data is shown which I sent from FPGA controller.
In the FSM, I have sent the initialization commands followed by my data, but no change. I doubt the signal voltage levels from FPGA are not sufficent to drive LCD, since it is only 3.3V signal. Please can anyone help me.

Abhishek
