▶ Product Description

The Measurement Computing MCC 152 is a voltage output and digital input/output HAT (Hardware Attached on Top) designed for use with Raspberry Pi®. The MCC 152 provides two 12-bit analog outputs with a 0 V to 5 V output range and 5 mA output drive, sourcing. Both outputs can be updated simultaneously with software. It provides eight bidirectional digital bits. Each digital bit is configurable for pull-up or pull-down, or can be disabled. Each output bit can source 10 mA and sink 25 mA. Users can configure the software to generate an interrupt when the state of a digital input bit changes. The MCC 152 can interface with 3.3 V or 5 V logic types. The input polarity is software programmable for normal (active high, default) or inverted logic (active low).

HAT configuration parameters are stored in an on-board EEPROM that allows the Raspberry Pi to automatically set up the GPIO pins when the HAT is connected. The open-source MCC DAQ HAT Library of commands in C/C++ and Python allows users to develop applications on the Raspberry Pi using Linux. The MCC DAQ HAT Library supports operation with multiple MCC DAQ HATs running concurrently. Console-based and user interface (UI) example programs are available for each API.
