I'm aiming to use a Beaglebone Black to measure some voltages. I have no problems with sorting out voltage dividers etc. to get the measured values down to less than 1.8 volts but I'm not so sure about how to protect the inputs against transients and at any time the Beaglebone isn't turned on.
Firstly, what's the usual method for preventing transients getting into the Beaglebone inputs? This will be a moderately noisy environment (a boat with 12 volt car style electrics). Secondly how do you ensure all the inputs are off until the Beaglebone has come to life? The measured voltages are going to be there 'all the time' regardless of what the Beaglebone is doing so there has to be some way of preventing the input being actually presented to the Beaglebone until it has powered up. Is there a standard (and simple!) way of doing this? -- Chris Green ยท -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
