As a prospective assembler of the JUNEBUG, Thanks to Mr Bill, but i have few doubts.
- why not use BS170 or BS107 in place of 2N7000. These are also N-channel types .
I will leave this one to BIll.
- whether 18F2525 or 18F2550 come with bootloader builtin or we have to load it. If so , how?
It does not come built in. You are to program it using another programer.
Easy to do if you can get the use of another programmer.
- even with much effort, i could not locate latest firmware for pickit2 i.e., ver2.02 ,if I am right
i was able to get 2.01 only, from microchip site.
It is OK to use the 2.01. MPLAB will update it for you auto-magic like.
