[sdiy] PIC / Atmel Programmers (usb)

[Bert Schiettecatte]

I don't like the FTDI chips. They appear as a virtual COM port or you have
to
use some weird DLL library they supply... so the device is still not usable
unless
you write your own driver or you write software the uses the library. So in
the
end, only your software would be able to use the device...

for usb...

check
http://www.ftdichip.com

easy to implement with any microcontroller, processor, fpga...or whatever
you are using that can use an external bus... they both have serial and
fifo parallel chips...going to use these chips in some projects that are on
my mind...

Also recommend to all :
check www.usb-instruments.com
cheap usb instruments that are pretty nice. Ordered that ANT8 logic
analyzer... $200 for a 8 channel logic analyzer... gotta love that price.

cheers,
Leif
