Summary †

This section discusses applications of AMI602 (G² motion sensor 6-Axis type), a 6-Axis motion sensor.
AMI602 is a product of Aichi Micro Intelligent Corp. The sensor is put on a DIP16 size breakout board
for better handling. AMI602 can be easily accessed from PIC/AVR and other one-chip micro computer
by I²C path. In this section, two examples are introduced. One example uses the module with a PIC
microcontroller, and the other is to make the module become a part of shield for Arduino.

• Manual of AMI 602 Breakout module (in Japanese ami602_readme.pdf)
  
• Data sheet of AMI 602 (in English ami602e.pdf)
  

Please do not contact with Aichi Micro Intelligent Corp for technical questions and/or supports. The
company does not support AMI602 Breakout module. (AMI602 Breakout Module is a product of
BeatCraft, Inc. If there are any questions and concerns, please submit to bc9dev.)

About VID voltage †

• Extra information form Aichi Micro Intelligent Corp.
  

  According to the recommended operating conditions listed on the data sheet of section [8], the
  recommended operating condition of VID is from 1.65~VDD (Typ. 1.8V), but there is a report
  that the some products use the sensors at the range between 1.65~2.4V. 
  It is true that  a sample schematic diagram notes VID = 3.3V, and  several sensors tested at Aichi
  Micoro Intelligent's office have worked well at VID = 3.3V.  Just reminder that if the sensor is operated
  at such level of voltage , it will be considered as outsides of the guaranteed operating conditions.
  Since the absolute maximum ratings of the sensor are between -0.3V and + 4.0V, the sensor does
  not brake down immediately. However, it will not work correctly. Please set VID is lower than 2.4V as
  using the sensor.

A sample with PIC 24FJ64 GA002 †

• Schematic Diagram
  • PDF bc10-002-0001.pdf
  • OrCAD BC10-002-0001.DSN
    • On the schematic diagram, DNI indicates that parts are not actually installed. C10 is added
      when the fluctuations of low frequency, which is generated form power supply are quite large.
    • C10 and C11are electrolytic capacitors, and other capacitors are ceramic capacitors. Especially,
      C3 should be the same type of capacitor as X5R or X7R .
    • The early version of PIC 24FJ64 GA002 cannot communicate through I2C1 correctly.
    • In some LCD character displays, Vss is defined as Vdd and vice versa. Please be careful as
      using some LED character display other than SC2004CS.display series.
    • To use backlit LCD character display, please be careful with the electrodes of the backlit LED.

• Sample Source Program MPLAB.zip
  • This program uses MPLAB IDE and MPLAB C Compiler for PIC24 developed by Microchip Technology Inc.
  • PICkit3 is employed as a debugger.
    • Register and compile the source file, which is created from unzipped compressed file. Then, write
      into the PIC.
    • The sample program is quite simple. Initialize the sensor and display the outcomes.
    • The serial port says 11500 bps, 8bit, None party, No hardware flow, and it outputs the debug
      messages.

A Sample with Arduino †

• Schematic Diagram

  AMI602 Breakout -> Pin # of Arduino 
  AMI602    1:    -> Arduino A5
  AMI602    2:    -> 2V (generated from 5V by power circuit) 
  AMI602    3:    -> Arduino A4
  AMI602    4:    -> Arduino D4
  AMI602    6:    -> Arduino D6
  AMI602    7:    -> Arduino D7
  AMI602    9:    -> Arduino GND
  AMI602   10:    -> Arduino 3V3

VID of AMI602 is from 1.65 V to 2.4 V, the level shift is required.

• Sample Source Programs
  • Arduino side AMI602_20100708.zip
    • Decompress the file, open up the decompressed file in Arduino IDE. Then upload it to Arduino.
      
  • Processing side AMI602PC_20100708.zip
    • Unzip the file, open up the file in processing. Then execute the program.
    • Use this file with the sample of Arduino side (AMI602.zip).
    • To Depend on its environment, change the configuration of the serial port.
    • To utilize the outputs of 3-axis magnetometer, the program can calculate and display the direction.
