hi, everyone !
well...i'm thinking of a system for a project. basically the idea goes like this: for the transmission part; it consists of RF Tx module, encoder and dip switch. the dip switch will set the transmitter address, rite ? this address has to match with the address of the decoder circuit at the Rx.
at the Rx, it will receive the

The best will be to interface to the existing two way radio through the audio input/output.

I have a pair of HT12E and HT12D. But they are only 4 channel.
I need to make a robot which will need multiple channels.
Given that the robot moves, I would need a motor driver. So only 4 channels would mean that the motor driver would run only two motors if I wanted them to run

How many tasks your pic have to change? If they are few, you can try a simple communcation implementing something like a encoder decoder. If you nned to change 2 tasks you can set an output 0 or 1 for tasks and read the PIN in second pic.If you need 4 tasks you can use 2 pins, 3 pins for 8 tasks and so on...
