to 8 MHz; (2) enable brown-out detection; (3) disable JTAG; and (4) disable erasing EEPROM when downloading a
new program. Please refer to the chip data sheet (www.atmel.com
) for a complete list of the fuse bits.
The following steps set the microcontroller to the suggested state.
If you are using BASCOM-AVR: Connect the programmer to your board as above, select “Send to Chip” from the
Program menu to bring up the Sample programmer window. Click on the “Lock and Fuse Bits” tab.
In the Fusebits section:
Click on Fusebit B and change the option to “0:BODEN enabled”
Click on FusebitA987 and change the option to “0100:Internal RC oscillator 8MHz”
Click on the WriteFS button.
In the Fusebits High section:
Click on Fusebit J and change the option to “1:Disable JTAG”
Click on Fusebit G and change the option to “0:Preserve EEPROM when chip erase”
Click on the WriteFSH button.
Close the Sample programmer window.
If you are using avr-gcc and AVRDUDE, downloading the FlashLED (or FlashLEDAlias) program will set the fuse
bits as part of the download process. (If you are setting the fuse bits manually, the changes above are accomplished
with 0xA4 for the low byte and 0xD1 for the high byte.)
