This one is going to be dependant on the OS. For example, in linux, I can read the raw data on the parallel port by doing some things with the hardware in C, and "read" the port. I take a look at the high (voltage up) and low (no volts) and determine an "answer".
You are trying to do serial information, so the data is going to be "organized". Your 10 bits might have 1 start bit, 8 data bits, and a stop bit. Your code will probably be OS dependant.
I would suggest doing a google search on this. For me, it would be Linux (as my Mac has USB and that is something else entirely) so I would search on "Linux Serial Port Programming" and I found this:
I couldn’t get to anything yet and probably will go in different direction: I was able to obtain the data from the port with Hyper Terminal. Now the question is how to obtain the data coming from 4 channels in a format of numbers from 0 to 1024 (10 bits), which changes every 0.25 seconds and to manipulate it with a C++ program?
OK, so HostGator for some reason no longer allows gcc/g++ access unless you have a Designated Server account, which is a lot of money to spend just to compile my "Hello World" program. Thus I figured I'd compile at home, then upload. Program is your regular old bare-bones Hello World ...
Hi. I have a form with list box : lst_product, datagridview : grd_order and button: btn_addline. lst_product has a list of product ids selected from database (MS Acess 2013) , grd_order is by default empty except for 2 headers and btn_addline adds rows to grd_order.
Hi, as I was told that my code doesn’t scale well at all, I thought perhaps I’d try to get a better understanding of interfaces/abstract classes and classes and the relationship between them.
I don’t want at this stage work on a big separate project as I've already got plenty ...
