- Added pic32 (Chipkit Uno32) compatibility
- Slotted transmissions for multilaunch events
- Active/passive buzzer support (DC/PWM driven)
- Removed MX146 support
- Battery (Vin) voltage sensing
- Branch into 1.4
Added readme, license and whatsnew files
- fix WProgram.h -> Arduino.h headers enables compilation on arduino 1.0+
- added flag for 2200 Hz tone pre-emphasis (actually done by de-emphasizing the 1200 Hz tone). Makes picky TNCs happier and a more intelligible signal at the expense of poorer FM deviation.
- shorten modem ISR. Now the AFSK samples are processed in the main loop and queued up in a fifo array. This results in a much lighter ISR, 0 overflow rate and a cleaner signal.
- bring baudrate closer to nominal (1200 bps) by using fixed point arithmetic to count samples per baud
- allow nesting timer interrupts inside the buzzer ISR to minimize chance of lost modem interrupts
update whatsnew
- renamed .pde to .ino since arduino <1.0 is old enough
- gcc 4.3.2 (Arduino 1.0.x) -> 4.8.1 (Arduino 1.5.x) deprecates prog_uchar, PROGMEM is now required
Added README.md for github
