Target Support Package™ FM5

QADC Digital In - Input driver enables use of Queued Analog-Digital Converter (QADC64) pins as digital inputs

Library

Target Support Package FM5/ MPC555 Driver Library/ Queued Analog-To-Digital Converter Module-64

Description

The QADC Digital In block allows you to treat the QADC64 pins as digital inputs. Each QADC64 module has two 8-bit ports, A and B. You can use any bit on either port as a digital input.

Dialog Box

QADC module

Select module A or B.

Port

Select an 8 bit port (A or B) on the module.

Bits

A vector of bits (numbered 0-7) to read. The vector should not be longer than eight elements.

Sample time

Block sample time; determines sample rate at which the port is monitored.

Mapping Bits To Hardware Pins

Use this table to work out how the block ports and bits map to processor pins on the MPC555.
