64 channel transmitter receiver

Wireless & IoT
1

I am thinking of constructing a 64 channel remote control.

I mean a 64 channel ON OFF momentary receiver and a 64 channel transmitter.

I want to use multiple receivers (with adressing method).

A PIC would be a good idea, anyone have something similar in mind? which PIC is suitable for this app?

Hi,

If activation time of the 64 channels is not critical, you could send 8 bytes + address over any standard serial rf module, where the individual bits of the 8 bytes sent represent the on-off status of the 64 channels. If this is ok, almost any PIC or AVR will do the trick. As an example, I did a project that allows a group of devices to communicate among themselves by sending or receiving packets of up to 52 bytes. Project details are available at the following link:

Hope it helps.

Hi and thanks for the reply.

Well … For how much delay are we talking about?

I was thinkinf of using a HOLTEK encoder-decoder or a PT from http://www.princeton.com.tw/webSite/temp/index.asp Princeton.

I could select address from the transmitter and send a 4 byte or 8 byte code (through their channell inputs) and use a Microcontroller to decode the binary input.

Or, instead of 8 bytes, send 9 bits: 1 bit channel state (on or off) and an 8 bit channel number. I’d toss in a checksum nibble for reliability.

Well… Since i’m a complete noob on programming it’s going to be difficult.

Does any one made something similar ever?

I don’t know where to start. I have one transmitter and receiver, have some PIC’s.

Thank’s for the replies :slight_smile:

Hi,

Have a look at the RF600T transceiver IC. I think it would fit your need nicely.

Seems nice but too complicated for me.

Thank’s again
