Serifus's Magical Dual-Mode AVR-controlled Flashlight

=====================================================

Our starting point was Selene Scriven (@toykeeper)'s [GPL flashlight firmware](https://code.launchpad.net/~toykeeper/flashlight-firmware/).

Requirements

===========

The avr toolchain:

```

sudo pacman -S avrdude avr-gcc avr-libc avr-binutils

```

avr-gcc and friends is the cross-compiler. avrdude is for flashing the chip.

You might also want simavr and avr-gdb but that's up to you.

(and make sure you have make installed, of course)

To test that you've gotten the toolchain working just use the Makefile:

```

[kousu@galleon serifuslight]$ make

avr-gcc -Wall -mmcu=attiny13      -std=c99  -g -Os    -o serlight.o -c serlight.c

serlight.c: In function 'save':

serlight.c:212:11: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

     eepos=(uint8_t*)cycle((uint16_t)eepos, EEPROM_SIZE);

           ^

serlight.c: At top level:

serlight.c:453:6: warning: return type of 'main' is not 'int' [-Wmain]

 void main() { //returning void saves a couple bytes (it's not like there's anyone to return to)

      ^

avr-gcc -Wall -mmcu=attiny13      -std=c99  -g -Os     -o serlight.elf serlight.o

avr-size -C --mcu=attiny13      serlight.elf

AVR Memory Usage

----------------

Device: attiny13

Program:     942 bytes (92.0% Full)

(.text + .data + .bootloader)

Data:         35 bytes (54.7% Full)

(.data + .bss + .noinit)

avr-objcopy -O ihex serlight.elf serlight.hex

rm serlight.o serlight.elf

[kousu@galleon serifuslight]$ 

```

If you see anything else you're probably missing a package or three.
