fuse bit for EasyLogger ?

Post by Tomex » Mon Mar 24, 2008 5:57 pm

I use PonyProg2000 program hex code from EasyLogger example.
But,I don't know the fuse bit should be programmed for ATtiny45 ?

Thanks

See the project's Makefile:

Code: Select all

# Fuse high byte:
# 0xdd = 1 1 0 1   1 1 0 1
#        ^ ^ ^ ^   ^ \-+-/
#        | | | |   |   +------ BODLEVEL 2..0 (brownout trigger level -> 2.7V)
#        | | | |   +---------- EESAVE (preserve EEPROM on Chip Erase -> not preserved)
#        | | | +-------------- WDTON (watchdog timer always on -> disable)
#        | | +---------------- SPIEN (enable serial programming -> enabled)
#        | +------------------ DWEN (debug wire enable)
#        +-------------------- RSTDISBL (disable external reset -> enabled)
#
# Fuse low byte:
# 0xe1 = 1 1 1 0   0 0 0 1
#        ^ ^ \+/   \--+--/
#        | |  |       +------- CKSEL 3..0 (clock selection -> HF PLL)
#        | |  +--------------- SUT 1..0 (BOD enabled, fast rising power)
#        | +------------------ CKOUT (clock output on CKOUT pin -> disabled)
#        +-------------------- CKDIV8 (divide clock by 8 -> don't divide)
