FTDI FT232
#1
Hi All,
I have a 18F2331 with a FTDI FT232R USB to a Serial IC. Currently, I am using the INTOSC at 8 MHz. Are there any known issues with this set up? I managed to get the boot loader to work, but not self reset using RTS.
I did a search, but didn't find anything

Regards
John

Hi Mikael, thanks for the swift reply. FT232 link below.

I have a 4K7 pull-up on the MCLR, and a 2N3904 in open-collector configuration, with the base connected to the FT232 RTS pin, via a 1K resistor.
Sorry I can't send a schematic at the moment, I'm replying from my ipad.

There is a working schematic sample on page 21 in the main manual:

Is your setup something similar? If you have a scope, take a look at the mclr pin while resetting.
Have you enabled reset by rts in ds30 Loader GUI?
