> what [ARM?] chips are you using? I=92ve been sort of arduino centric recently, so I=92ve been looking at the= low-end ST chips (STM32F103), and the low and midrange Atmel ARM chips (SA= M3X (=93Due=94), =93SAMD21=94 (=93Zero=94), SAMD10=85 Also the TI Stellaris =93Launchpad=94=85 I=92m mostly using the ARM gcc command-line tools. https://github.com/WestfW/SAMD10-experiments https://github.com/WestfW/Minimal-ARM (although I have some other ST, NXP, and Cypress eval boards as well=85) Jumping to ARM and only looking at a single vendor is =85 missing the point= , IMO. I also have some ARM-based unix boards (Raspberry Pi) and =93hackable devic= es=94 (=93Chumby=94, =93Pogoplug=94, =93Juicebox=94), but I haven=92t reall= y gotten around to doing anything with them. Giving up microcontroller hac= king to become a unix sysadmin doesn=92t seem like as much fun as I=92d hop= ed :-( BillW --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
