Pacaxe 20x2 and 10 adc's Radio control

[andyquirot]

Hi all have a look at the drawing i am thinking about building a 10 channel radio control system.
1. Transmiter will use a 20x2 Picaxe with 10 adc's on 10k pots
2. The thought is read the adc's and send the valules out the serial pin to a 2.4ghz Tx
3. Read the 2.4ghz input to a Picaxe 20x2 reciver and then use servopos to control 10 servo's

Comments and iders (Do you think it will work)

Will it work?
That really depends on what you mean by work!

If you want to send 10 pot values via serial via radio and use the values to set servo positions, then yes.
If you are expecting to use those servos to control an aircraft flight, then no.

The problem will be response time between moving the pot and the servo moving. For a ship or maybe even a slow ground based vehical it will probably be OK. For anything that requires real time active control, then it will be too slow.

Thanks for the quick reply i did not think about the speed as i thourght seting the freq to 64mhz would be quick as i am only sending 10 bits of data.

It's not so much the speed of the PICAXE but the speed of your serial link.
Each value will need to be sent in sequence and you will only be able to send it at the maximum serial speed of whatever radio you are using.
