H8S/2633 Project: Creating a "Propeller" Display

This project uses the H8S/2633 to create a working LED matrix display. The display is unique because it is a moving propeller that makes a cylindrical ribbon of light for graphics and text. The project uses the Programmable Pattern Generator to create the light sequences, and it reads an encoder to obtain position info.

Light Power Meter Based on H8/38024

Contains code to create a big banged version of an I2C interface, LCD display code and an interface to an external Trans Impedance Amp. The "product" does logarythmic readings of input light power. The device takes advantage of low-power modes on the 38024.

Low-power H8/38024 Yoga Timer

This is a project is for a Yoga Movement Timer. The project contains code to perform button scan and debounce, with audio feedback and a 4 digit LCD display. Most of the code switches to sub-active low-oower mosed when not interacting with the user.

Aux Auto Heater Control and Timer

This project creates a timer for setting up auto engine block heating for cold climates. The system allows setting of multiple time periods in an hour, day, week format. The actual project uses HMON for debug and a backlit LCD for the display.

Front Panel Control using H8/3687

This project contains info on gathering and transmiting IR remote control codes used in an A/V switching/routing device. The 3687 acts as a front panel controller handling messages and making changes to the relay configurations. The code uses RS-232, 485, LCD, switches, and local/remote IR transceivers. This code also shows how to implement a Wake on Interrupt function on the H8.
