Someone mentioned the Nokia 3310 mobile phone LCD as a useful small
graphics/character display on the PIClist. They are available quite cheaply
from several sources so I've ordered one (about 16 GBP). The nice thing
about them is that they have an I2C interface and will therefore connect
directly to an LPC2100 device.

I could have saved some money by taking the display out of my phone, of
course. 8-)

Not really an LPC2100 issue, but this is a helpful group.. I need some
remedial help in thumb/arm interoperability in GCC, particularly with
assembler gets involved.  For instance, how __asm__ macros for basics
like enable()/restore() know what mode the calling code is using.  Also,
for assembler routines in .s files (context switch, etc.) it seems that
the architecture would best support the *caller* knowing whether a
routine is ARM/Thumb, although this is not the way it seems to work.

Are there any good code examples that get into the hows and whys of
issues like these?

I have a 3310 display connected to an MSP430F169 on a SoftBaugh DIr169
board.  This uses SPI for communication, not I2C.  Chris Speck at TI
wrote the graphics display routines using CrossWorks to support the 3310
with the 169's SPI interface.

Chris said that the 3310 display cost him about GBP 3.

You are right, it is SPI. I think the original posting I saw said it was
I2C. I prefer SPI, anyway.

Here is some code for Hi-Tech PICC:

but it's a bit easier to use the LPC SPI hardware.

I made NOKIA 3310 LCD subroutine by assembler.
(But it use software SPI routine.)
