Target Devices

  • H8S/2218U

Product Overview

The 3DK board consists of an H8S-2218Umicrocontroller (MCU) mounted on to a circuit board with 8 independent LEDs connected to an I/O port to allow simple visual output from the MCU. Two switches allow interrupt input to the MCU and a variable resistor is connected to an Analogue-to-Digital Converter (ADC) input allowing an analogue voltage to be measured. The board can be interfaced to a PC via the RS-232 port where C-coded programs may be downloaded to the MCU using the HMON debugger software provided. Also provided is a header connector around the MCU which provides access to the MCU I/O pins.

Main uses for the 3-D board:

  • Demo tool where the basic functions of the MCU can be tested or demonstrated. Sample programs on the CD-ROM can be downloaded to the MCU via the serial port.
  • Benchmarking target board for evaluating the MCU performance, allowing compilation, debugging and benchmarking of the user's own code.
