ADC.waitForLower(port, value, [frequencyMs], [ezbIndex], [timeoutMS])

Parameters

port Analog port to read from.
value Exclusive upper bound on value to wait for.
frequencyMs (optional) How often the port is checked in milliseconds.
ezbIndex (optional) Board index of the EZB to read from.
timeoutMS (optional) Number of milliseconds to wait before timeout.

Returns

The value read from the specified ADC port that is lower than value. Returns -1 if timeout

Description

Suspends execution of the script until the value read from the specified ADC port is lower than value. The value read from the ADC port ranges between 0 and 255. If frequencyMs is provided the port is checked every frequencyMs milliseconds. Otherwise the port is checked as often as possible.
