To demonstrate the versatility of Hitachi’s H8 family of microcontrollers, Avnet Design Services’ Technical Support Center (TSC) has created the Inclinometer. The Inclinometer is a display instrument that renders the amount of forward/backward roll and side-to-side tilt from a level plane. The Inclinometer can be utilized for applications such as curve acceleration meters, sailboat heel meters, or logging devices for vibration analysis equipment.
The Avnet Design Services Inclinometer features:
-
Hitachi H8/300H Microcontroller H8/3048F
-
Hitachi LCD Display LMG8400PLGR
-
Analog Devices Accelerometer ADXL202
Specifications
Roll and tilt are represented in +/- degrees from zero. Key feature parts provide the Inclinometer the ability to operate from a battery source, sense gravitational forces, and display the results. The H8/300H handles key power management issues, obtains and displays the sensor results and logs the data set. The H8’s on-board flash allows the unit to be upgraded with enhanced functionality. This combined with the Analog Devices ADXL202 accelerometer 2g-measurement ability allows the unit to be programmed for numerous different applications. Inclinometer features and functionality:
-
Battery powered • External DC power adapter option
-
4" x 4" 240 x 128L CD dot matrix display
-
Hitachi powered
-
RS232 PC interface
-
In-circuit re-programmable flash
-
Compact overall size, approximately 4" x 4"
-
Accelerometer provided the X- and Y-axis measurements
-
Expandable with the aid of additional software allowing for the adaptation of the unit to measure G forces in X and Y co-ordinates (based on in-circuit re-programmability)
