i need the source code of interfacing the microController LPC ARM7 2119 with an LCD 128*64 thank you
There are no "the source code". While most LCD displays are using any of a small set of display controllers, there are actually more than one on the market.
Also, the LPC has a lot of pins. They may be combined and used in a large number of ways, i.e. there is a large number of ways to connect an LCD display to a microcontroller. Especially since different displays may interface using a (ttl-level) RS232, SPI, I2C, 4-bit parallel, 8-bit parallel, ...
"... the LPC has a lot of pins ..."
When Philips (now NXP) started their "LPC" ranges of processors, I thought the "LPC" was supposed to stand for "Low Pin-Count".
But now, as you say, there are "LPC" parts that have High Pin counts!
Was I mistaken, or have NXP/Philips just forgotten...?
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.
Go to yahoo groups and search for "lpc arm". There is source code in the download area of the lpc 2000 user group for graphic LCD's
