Hello all,
I have previous PIC experience but am looking for a more capable micro to help me take over the world with.
I would like to move into the embeded line of things and eventually into the arm7/9 and xscale development would the LPC2148 be a good starting point?
Nobody I know has used the LPC and im not even sure what arm generation it is but im attrackted to its specs and massive amount of GPIO’s
Anyone have any love / hate stories they could share with me??

I have 2 LPC2148 boards and I love the chip. It’s fast, has loads of I/O, and is easy to use and program. It’s built off an ARM7 core.
Good choice IMO, make sure to read the errata and read about the spurious interrupts and workarounds.
I did quite a lot of research before I jumped into the ARM world. I chose the LPC2148 for several reasons, including the 512K of flash it has.iceblu3710:

The LPC2148 also has TWO EACH of I2C and SPI bus controllers. The I/O pins do not conflict with other peripherals. It’s really nice to be able to have SPI and I2C active at the same time. I am getting the [LPC2148 Proto Board as soon as they are in stock. I have the [LPC2148 Header Board, but I seem to have managed to brick it and don’t know if it is recoverable.
The only PIC I have found to date that has this setup is the 18F87J50.

Thanks for the quick responses, The biggest pic I have used is the 18f4550.
Whats the tool of choice for IDE/compiler?
If you need a windows free toolchain you may try YAGARTO, it worked well for me.
The LPC2148 would be a very good starting chip.
Any high quality IDE out there? If theirs a a good suit out there im willing to pay for it.
Also anyone seen this before? http://www.mikroe.com/en/tools/easyarm/
Rowley Crossworks is very good, with excellent support.

I used 12 of the low cost Coridium ARM7 wireless boards on a project. This is an LPC2103. They also have a 2106 product.
They just released a new version of their BASIC compiler/IDE - closer to VB6 now. Free.
And they have a free IDE with GCC.
I have a couple lpc2148 header boards, and they are very easy to use. I use lpc21isp with a usb to UART breakout to flash it, and the arm-elf-gcc toolchain to compile C programs for it. It’s nice, lots of IO, fast, and the isp bootloader is really handy. Plus, they’re cheap.
