Just an update on this. I’ve been working on interfacing a few sensors and things and everything has been working fine. The only issue is that the programming interface is not very fast. I haven’t played with settings or anything, but even with a divider of 1 the programming for a 10k load takes about 10 seconds. The extra hardware breakpoints are very useful.
I haven’t played with sleep modes yet, but my understanding is you need to be careful with deep sleep. If you put these things in deep sleep mode right away, you make it inaccessible via the SWD, so you want to make a long delay before doing that.

So, 10K/second using a FTDI device? I forget what we get, I’ll benchmark tomorrow.
BMP085 – excellent, I have one of those and wrote a driver for it too. I happened to use the Jee Labs Pressure Plug on a Plug Shield linked to a 100MHz Stellaris device in Arduino format.
Any chance you’d be able to post your code for the LPC1114+BMP085 combination in Crossworks, I’m playing with exactly that combination (plus some more bits) as well and all my time is being sucked into struggling over board bring up issues at the moment (I didn’t prototype I went straight to a custom PCB thinking this was really staightforward… and its not the easiest thing to debug the way I did it… I’d do better next time though :-)…(currently my cp2102 USB-serial chip won’t enumerate and thats my console to the device…).
A code jumpstart would be appreciated :-), all I’m doing right now is wiggling lines to test for life, but so far the environment is far more stable than Microchips, the chip is cheaper and more powerful and the only downside is a little more complexity and not so much documentation (or field experience)
I’ve got most of my code running (sort-of-ok-ish) on a Microchip PIC18F2455 but HATED the environment, the bugger ICD3 debugger and compiler and the limitations of the chip/compiler/ICD3 combination… pretty much everything else about that environment too…
Anyhow a nudge in the right direction from a master coder would be great…
