v1.0.7 - fixed DAC bug, restructed to use new Arduino boardtype menues

Initialize VREF at 1st usage of DAC,

R
ATmegaxxM1-C1-1.0.7.tar.gz
estructured to Arduino menu selections, added menu options for PWM initial state (Thank you Geraldjust).

v1.0.6 - Enabled TONE, corrected SerialWrite IRQ race issue

TONE is now enabled, though it conflicts with PWM (analogWrite) as the same timer is used.

A bug in SerialWrite was corrected that caused serial writing halts during high IRQ situations (e.g., while external CAN was running hard)

v1.0.5 - Refinement of DAC and Diff Amp support

v1.0.5 --> pinMode(DAC_PORT,xxx) disconnects DAC from port (is connected by analogWrite(DAC_PORT, xx). analogRead() differential ports corrected for +/- values.

v1.0.4 NEW --- Actual release using NEW CORE files

This is what is in the actual v1.0.4 release. It is a re-port based off of the newest release of Arduino CORE files from their v1.6.8 release of the IDE

v1.0.4 OLD --- Last edits to old CORE files

This release contains the final edits made using the OLD core files. It includes some additions include analogWrite support for the ADC, and some small corrections.

After this 'release' the port will be based on the latest Arduino CORE files, bringing this release up to date.

V1.0.3 - correct CORE files

Correct issues in the CORE files, and specifically around serial.write to prevent hangups.

This releases is suggested to be used with the avr_can lib, as during high loads the error in the CORE file can cause hangs...
