A simple question -

is it possible (how) to activate an existing device which is a general PIC16F684 device thru the a usb peripheral (pic16C745)?
Meaning - my pc should be able to activate the PIC16F684 device via a software and the USB peripheral of the pic16C745.

 

what exactly are you trying to acomplish?
EDIT:: acComplish. ops:

 

It didn't make any sense to me either?.

hi guys,

first thanks for your reply - i'll try to explain...
i have an existing device (pcb) which is controlled by a microchip PIC16F684.
what i would like to do is to be able to activate the device via a pc by using a usb peripheral.
to my understanding - the best way to do it would be by designing a usb peripheral which is based on a microchip PIC16C745.
my question is if my assumption is right about being able to do so by using the PIC16C745.
for that matter, i guess my question is if the PIC16C745 device would be able to control/activate an external circuit by a simple on/off switch.

thanks,
gil

 

The 16C745 is a standard 14 bit PIC, just with the addition of a USB interface - you can do anything you like with it, it's just a question of writing the code. From your vaguely worded question, I'm presuming you're only wanting to take a pin high or low in response to a particular signal received via the USB interface?.

The 16C745 is OTP, but a FLASH USB PIC is supposed to be due shortly.
