I am reading voltages on AIN0 and AIN1, the voltage on the pins is almost exactly 0.9 volts, I have measured it quite carefully with a multimeter and this is the voltage I would expect given the dividers I'm using.
The raw value from the ADC is 896 (plus or minus a count or two). It really is reading the voltage as, if I increase or decrease it a little, the reading goes up and down. However this means that the ADC actually has a full scale reading of only around 1800 for 1.8 volts, that's not a 12-bit ADC it's closer to an 11 bit one. Is the ADC set up so that the reading actually represents the voltage (i.e. 1800 is 1.8 volts)? Anyway I think the specification misrepresents the ADC accuracy. -- 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.
