mjb/altos/src/lpc, branch new-state AltOS - the operating system for Altus Metrum products https://git.ethernal.org/mjb/altos/atom?h=new-state 2013-10-08T16:22:03+00:00 Add --with parameters to configure for compiler selection 2013-10-08T16:22:03+00:00 Keith Packard keithp@keithp.com 2013-10-08T16:22:03+00:00 urn:sha1:6a1e398e590121458176758858bb4210f3eb5a55 This allows the user to specify which compiler to use for each target CPU. Also checks to make sure the arm compiler supports -m0 and -m3 cpu type flags. The build now actually uses the specified compilers too.

Just use single conversions and take an interrupt per channel. Also, slow down the ADC so that our values are more stable -- just need to make sure we get the whole conversion sequence done 100 times a second.
