Is the AVcc always max available voltage output approx 3v?
If I want to read values from a flex sensor the flow is AVcc to Flex to
(Voltage divider) Vout = ADC0? Do I need an Op Amp?
Does R2 from the Voltage divider go to the 9-pin on expansion connector?
If Vref is at 1.5v, incoming voltage at ADC0 should not succeed that?
Thanks,
Mikael

Hi,
What voltage should I expect by meassuring AVcc and ADC0 with following
enum in TelosADC:
enum
{
TOS_ADC_FLEX_PORT = unique("ADCPort"),
TOSH_ACTUAL_ADC_FLEX_PORT = ASSOCIATE_ADC_CHANNEL(
INPUT_CHANNEL_A0,
REFERENCE_VREFplus_AVss,
REFVOLT_LEVEL_1_5
),
};
