The Programmer’s Guide to the PDQ Board
This single board computer is ideal for data acquisition and instrument control.
This single board computer (SBC) performs data acquisition and control, packing a Freescale 9S12 (HCS12) microcontroller, memory, communications, dozens of analog and digital I/O lines, and dual expansion I/O buses onto a low cost 2.5" x 4" board. The embedded controller dramatically cuts the cost of data acquisition and control. It is easy to program in either the Forth or C languages using the customized IDE (Integrated Development Environment), and includes pre-coded device driver libraries and a real time operating system. This fast low power microcontroller is ideal for measurement, instrumentation, industrial control, SCADA, automation, and data acquisition.
This programmer's guide provides a thorough explanation of the PDQ Board's Freescale MCU, the HCS12/9S12, and an introduction to its software and hardware interfacing.
