If I load the standard, basic, blink program from the Arduino IDE, the arduino pin 13 stays solidly lit. If I modify the program by putting Serial.begin(9600); in the setup() function, pin 13 blinks as the standard program should be doing.
If I take the standard blink program, without the Serial.begin line, and change the delays each to 1, the LED on pin 13 flashes breifly, then stays off.
I've checked the fuses vs my boards file, and I've even tried reflashing the boot loader... I'm not sure what's up here.
The information I got from my boards file:
Code: Select all
uno.bootloader.low_fuses=0xff
uno.bootloader.high_fuses=0xde
uno.bootloader.extended_fuses=0x05
uno.bootloader.path=optiboot
uno.bootloader.file=optiboot_atmega328.hex
