|
* PEGLEG CPU is responsible for:
|
||||||
|
* - aux gpio (todo: list specifically which GPIOs on the badge)
|
||||||
|
* - eye RGBLED matrix
|
||||||
|
* - temperature sensor
|
||||||
|
* - light sensor (using eye RGBLEDs; in practice uses the left eye red LED)
|
||||||
|
* - user config eeprom
|
||||||
|
*
|
||||||
|
********
|
||||||
|
* Use the following fuses for this project. Needs to run at 8MHz for 400khz I2C operation.
|
||||||
|
* 8MHz, self-program enabled (bootloader support), preserve EEPROM, BOD disabled, ISP enabled
|
||||||
|
* -U lfuse:w:0xEE:m -U hfuse:w:0xD7:m -U efuse:w:0x00:m
|
||||||
|
* (efuse will likely show as 0x06 after setting; this is fine, don't worry about it)
|
||||||
|
*
|
||||||
|
* Resources used: Mainline ISR 5% (3/63 timer counts simulated, as of some old rev)
|
||||||
|
* Flash 26.8%, SRAM 10.4% (as of the above rev)
