Hello everyone, I am trying to build a circuit that will allow 2 PC's to communicate wirelessly to fulfill the requirements of a communication course. I am in my junior year of a BS program in Electronics and Communication. I intend to use the RS232-DB9 serial port. I need help in this regard.
My problem Definition is as follows:
1. PC A generates some data. (Text/ASCII chars) It is output through its serial port by using a C program.
2. This data then needs to be sent to an RF module that modulates the data bits using a modulation scheme (like FSK) and transmits it.
3. It is received by another RF module, which then hands over the data to PC B.
Here are a few questions I have:
1. Do we need MAX232 Line drivers and a microcontroller (for what function) to interface between the PC and the RF module? (I am acquainted with programming of the 8051)
2. Does circuit complexity increase drastically if we implement in Full Duplex? (Currently considering MT8870D or MT8888C)
3. How would one go about doing the PCB layout...does anyone have relevant schematics with layouts and circuit details?
Thanks for your time….
