pic i/o card project
Hello!
There is an application note here that seems to do exactly what you are looking
for. I implemenented it for a device that outputs about 5 kbytes per second,
so I guess if you want to update 10 times per second, it will be fine. Depends
how many bytes you send every time. Anyway it works fine with hyperterminal
which is also one of your conditions.
Look at the following document:

And download the related source code.

If you read carefully, if you use exactly the suggested code,
install the drivers and so on, it should work at once before you wrote
your own first line of code.
Now if you use another processor, you should use one with a USART and
rewrite the USART calls accordingly. But the minimal trouble solution would
be to use a MSP430 (you get analog inputs so you can implement all what
you want).

pc connectible External I/O card which uses usb to connect with pc
1.not allowed to use pics containing the usb protocol stack inbuilt
2.it should have 1 anlogue i/p & 1 analog o/p,2 digital i/p & 2 digital o/p
3.should operate with the power available in the usb
4.when plugin should detect automatically
5.implement a real time terminal (like hyperterminal for serial port) ,should have updating data rate at least 10 times per second
