Thanks Mark,
I didn't know there were people selling flashed pics, and yes I've seen
those posts where one can read sillicon labs seems to have had problems with
their gpl-understanding.
However, I asked them for two samples, as I did with microchip a while ago.
So at the end of the day I end up having a usb <=> rs232 cable for free.
With that I might be able to flash my first pic. I mean, I'm not trying to
use cp210x for a project in particular. Just to be able to launch off from
cero.
I've even found software for uploading, such as minicom and cutecom. So I if
I can see some schematics, good, and if not will try once they have arrived.
Now I guess it's time to reread gpasm or sdcc and about the pic theory
(config bits, etc).
Thanks.
