I don't know if anyone on the lists does anything with Arduino stuff or not. Figure I'd give it a shot.
[Q1] The 6 pin ICSP (in circuit serial programming) connector: Is there anything special about the 5v pin on the ICSP header? is it just a static 5v dc? Or does it turn on/off at a certain times during programming or change to a different voltage during programming? [Q2] ICSP and brand new parts So, I've been programming everything using the AVR dragon parallel programmer. I got some parts from digikey and drop them in the parallel programmer and set the fuses and burn the code I want. Can I program brand new parts using the ICSP? change fuse settings? Download new software? Does the board have to have an oscillator? I tried jury-rigging something to program the ATtiny13 with a home made ICSP connector, but I couldn't get it to work. Thought maybe I should see if it can actually do what I want it to do. Maybe I just had something hooked up wrong, but I couldn't find it. [Q3] crystal frequency How hard would it be to run an arduino at something other than 16mhz. It looks like every arduino available commercially runs at 16mhz except for one model which I think was a Lilypad which ran at 8mhz. Anyone familiar with the bootloader know how much of the code has 16mhz hard coded into its assumptions? _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
