Reading 3(maybe 4) servo control signals

[radiogareth]

I'm wondering if anyone has successfully got any Picaxe to read 3 or 4 servo control signals from a R/C receiver. A search reveals that they will need reading in sequence, that's OK, its does not have to be that fast as its not for a plane or car project, just some motor control on a project - 1 H bridge driver and 2 Chinese steppers. ANy code snippets that are known working would be great

Thanks

I've never done it but it should be possible if speed is not an issue. This thread discusses some of the details.

Here's some sample code from that thread:

do

pulsin c.1,1,w1
pulsin c.2,1,w2
pulsin c.3,1,w3


sertxd("C.1 pulse = ",#w1,13,10) 
sertxd("C.2 pulse = ",#w2,13,10)
sertxd("C.3 pulse = ",#w3,13,10)

loop

Good Luck,
Rick

I can confirm that it works fine. Just got to build the rest of the programme now ;-)
