i am currently working on USBtinyISP, specifically programming the microcontroller.
because i do not have a programmer i am using an arduino duemilanove as the programmer.
i uploaded the sketch from here (avr910_ard.pde , other versions make avrdude hang)
before uploading the actual code for USBtinyISP, i tried to upload 'test_leds.hex' ( from here ) but i get a nasty error:
Code: Select all
Found programmer: Id = "AVR ISP"; type = S
Software Version = 2.3; Hardware Version = 1.0
Programmer supports auto addr increment.
Programmer supports the following devices:
Device code: 0x01 = (unknown)
Device code: 0x56 = ATtiny15
Device code: 0x76 = ATMEGA8
Device code: 0x5e = ATtiny2313

avrdude done. Thank you.
os is windows 7.
what should i do?
also, how do i complile the firmware for USBtinyISP? Make doesn't work for some reason...
thx.
solution:
after a little digging, i found out why when using the newer sketches avrdude was hanging.
you must specify the baudrate manually, '-b 19200'.
