i need the source code of interfacing the microController LPC ARM7 2119 with an LCD 128*64 thank you
The nice thing with the LPC chips is that they have a high level of "redundancy" in their pin assignments. Most signals can be mapped to at least two different pins. This makes it possible to use a very large part of the built-in hardware features without suffering the usual pin collisions.
I would say that they have a very low count of unusable pins.
