Re: [Paparazzi-devel] re: Razor IMU Wiring Diagram

[Simon Wilks]

So in the case of Ana:

ADC_0 = IRV connector (pin 3)
ADC_1 = IRH connector (pin 4)
ADC_2 = IRH connector (pin 3)

ADC_3 = ADC1 connector (pin 5)
ADC_4 = ADC1 connector (pin 4)
ADC_5 = ADC2 connector (pin 5)

And power can come off any of the connector's 3.3v pins. Ground from
any ground pin. Correct?

In example_twog_analogimu.xml it uses the first three above but in
place of the last three it uses:

ADC_5 = ADC2 connector (pin 5)
ADC_6 = ADC2 connector (pin 4)
ADC_7 = USB connector (pin 8)    really?

Also good? Does it matter which combination I use as long as whatever
I take is defined in the config?

Thanks,

Simon
