i have been trying to work out why my Diecimila clone wont start up.. there are no bridges and the usb to serial section works fine.
I tested it by wiring it up to the Boarduino using the serial, reset, +5, and gnd. it uploaded sketches perfectly.. there was no chip in the Diecimila naturally.
but when i have a chip in (i got a new working atmega with blink on it) nothing happens.. i'm thinking when the old ship went down it took the crystal with it
Seeing as i have no replacement to test this theory what can i use in its place?. i assume it has to be 16 mhz so 4 wont work (i got 2 4 mhz oscillators in my harvest box, but they are 3 pin like the usb one and the one on the Boarduino).
Can a 555 timer be used in any way to emulate it? if so how? i just need to know if it is the crystal or not and i cant think of any other way of testing it to be sure.
