I've just build a project running from 3 AA batteries, using shut_down sleep modes to cut power. first i had it running on the lilypad 8Mhz bootloader, but later i switched a fuse in avrstudio to let it run on 1Mhz. but now the bootloader won't work, expecting it to be running on 8Mhz. then i thought about making another board entry in the arduino IDE and copied the lilypad folder in the hardware/bootloaders folder with the non inspiring name batDuino.
then i edited the makefile in the src directory
# enter the target CPU frequency AVR_FREQ = 1000000L # enter the parameters for the avrdude isp tool ISPTOOL = stk500v2 ISPPORT = usb ISPSPEED = -b 115200
but, running on 1Mhz, can the atmega cope with the 115200 baudrate and if not, does the IDE listen to the ISPSPEED var here so i can set a slower speed?
and to conclude this questionare, how would i make a hex file out of it, be it on mac osx or avrstudio on pc?
Am i on the right track here?
