ZBasic System Library 137 ZX Microcontroller Family InputCapture Type Subroutine Invocation InputCapture(data, count, flags) InputCapture(data, count, flags, timeout) Parameter Method Type Description data ByRef array of UnsignedInteger The array in which pulse width information will be stored. count ByVal int16 The number of pulse widths to store. This should be no larger than the number of entries in the passed array. flags ByVal Byte A value of zero requests that a falling edge begin the capture process while a value of 1 indicates a rising edge. All other values are reserved. timeout ByVal Integral If non-zero, this parameter specifies a timeout value that, if exceeded, will terminate the input capture process. Discussion Invoking this routine is equivalent to the call InputCaptureEx(pin, data, count, flags) or InputCaptureEx(pin, data, count, flags, timeout) where pin is the default input capture pin for the device as shown in the table below. See the description of InputCaptureEx() for more detailed information.

This implementation requires the data type to be UnsignedInteger or Integer although it needn’t be an array. For practical purposes, an array will almost always be used.
