I have switched almost totally to ARM, because I was fed up with the=20
not-exactly-standard C for PICs, and the shock of MPLABX.

I use mainly LPC1114 (DIP28) and LPC810 (DIP08), with C++ using a=20
standard GCC (free from https://launchpad.net/gcc-arm-embedded), and=20
serial download using LPC21ISP. I don't use a debugger, I prefer writing=20
to std::cout (via the UART to the PC).

I write my own linkerscript, support libraries etc. The last-year=20
version can be found at http://www.voti.nl/bmptk , I am working on the=20
next version. It supports coding in assembler, C and C++. (Which happen=20
to be the languages I teach.)

I use C++ because it can be used to write code, especially libraries, in=20
a very abstract/configurable/flexible way, but without sacrificing=20
run-time size or speed. An article on this (objects: no thanks!) can be=20
found at=20
