at what speed is an AVR programmed? Is it dependent on clock fuses?
I have an AVR set up with an external crystal clock in circuit (on a breadboard), and it programs fine, but when I move it to a circuit on a protoboard without a crystal, it won't program.
I initially thought it wasn't programming because I forgot to use decoupling caps, but I've added these now, and it doesn't seem to work without an external crystal.
I initially thought that AVRs program at a constant speed (which would allow you to recover if your crystal blew or was damaged), but now I'm wondering.
Probably a stupid question, but I have to ask. Even better, if you could point me to where I might find this information in data sheets, I'd love that. Tried looking, but I couldn't find anything amidst the whirlpool of information.
