Hi
I'm using the ft232rl chip in a self powered configuration i.e. it's powered by an on board 5v 7805cv regulator.
In the datasheet it said I need to setup a voltage divider to produce 3.3v which should be powered by the usb port. I was wondering does it matter which ground I connect it to because I connected to the gnd of my regulator simply because it happened to fall into the same column on my stripboard. However I was told the gnd pin for the usb port should be connected to my regulator. So is it not effectively the same?
