ASF I2C library for SAMD does floating point, causing bloat
apparently  _i2c_master_set_config() does this poorly documented: It turns out (http://www.eevblog.com/forum/mic... ) that the ASF function _i2c_master_set_config() uses...

External Interrupt (EIC) on multiple pins
The SAMD chips only seem to have 16 EIC channels, and up to 7 pins (on sam51p) can share the same channel.   Is it the case that if I enabled multiple pins on the same...

avr-gcc error messages extra verbose...
The way that avr-gcc (probably gcc in general) handles the #error and #warning processor commands has changed, and gotten a lot messier.   In GCC 4.3 (WINAVR) make atmega328...
