An automated RS232 data transfer between my program and a microcontroller
Posted on 2005-03-28
To start off, my program is written in MFC style.
I've got a dialog box, where on the push of a button, ive got to transfer data between our microcontroller and my program.
The microcontroller side I'm not too worried about because there is a built-in interface already for it. (its in the motorola 86x familty i believe..the hc11)
Could someone give me a good place to start?
the baud rate should always be consistent as well as transfer rate, headshaking, etc.
I'm not sure what the protocol for the RS232 is and haven't been able to find a good source online anywhere.
I'm not quite sure even how to open a COM on my computer (thats how much i know...-___-;;). My laptop doesn't have a serial interface, but i have a usb-to-serial cable that i will be using.
Any guidance, and help will be very very greatly appreciated!! C:
