    aaSo ive been looking around at the USB Host/BlueTooth since ive somehow managed to kill my serial BT module :/. I also want to be able to have my bot wirelessy brodcast info on a TV.

    So i know the usb driver takes 4 cogs, im not sure how much space it takes the forum link is broken on obex. Anyways obviously if i go the propeller usb host route im going to need two propellers but im wondering if i should be able to squeeze the usb driver and the tv driver with graphics on the same propeller. I have a dedicated usb host board, but i would like to use that for something else and im not sure if you can use a hub with them, plus this way i dont have to write a BT stack.

    I have a few extra props around and usb bt dongles so this will allow me to get my radio control back working for free and it will also give me the option to write a bt hid driver later becuase ive got a kb id desperately like to use down the line.

    What do you think? How much compiled code do you think each will take? For TV graphics, how big do you think the buffer would be? We're not talking rocket science to get a very rough estimate of how much memory is needed. You've got 32K to work with. I'm sure you could figure it out with a little bit of work.
