Over the last year, I have increasingly found the need to run parallel picaxe's.
In this current project. I am using a Hall sensor, like a rotary encoder.
The problem I am having here, is the same as I often have. Not enough processor time to run everything else and count pulses from the hall as well.
So what I am think of doing. Is to use an 08m2; just to do the counting of the pulses from the hall sensor. Then transfer the data to the main processor when it has the time to collect it.
But this project is power usage sensitive. And I don't want the 08m2 powered continuously. And the cable run is 1m between both picaxe's. So i would prefer not to have to run another lead to tell the 08m2 to turn off.
Instead, use the an output from the main picaxe to power the 08m2. The current drain of the 08m2 and the hall sensor will be lucky to make 10mA peak.
I know its an odd way of going about this. Does anyone see a problem with this?
