Hi all,
I'm working on a personal project where I want to connect my digital weighing machine with my PC so that whenever I check my weight, it is recorded in my computer (excel file) and I can check the progress of my weight. (I'm bordering on marginally underweight, and am desperate enough to make devices to increase weight )
This is what the weighing machine looks like
I'm assuming that if I just connect the LCD display to the PC, I'll have the bit's needed to compute the numbers through software. (Connection on the inside:-
I need to send the 2 bytes from the LCD to the PC, most probably serially. I'll be using a parallel to serial shifter (16 bit shift register) to transmit the 2 bytes serially.
My question is this: Should I use USB or the serial port?
From my research on the internet and this forum, USB seems like a very complicated solution. I only want to use it because it would be simple to use anywhere: serial ports aren't there on laptop's and some PC's now...
Isn't it possible to just poll the usb port for bits and store them?
I've been researching on this for a couple of days now to no avail, so any help would be really appreciated.
Thanks in advance kind people
