interfacing an LCD 128*64

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
