This Automatic mode is the most simple lib for MCU Gear. You don't need to think about Bank.

This is a MCU Gear Automatic mode library.

(日本語は英語の次に書いてあります。)

MCU Gear is a digital wiring extension board.(A kind of dynamic circuit changer.)

It can change its wiring dynamically, without the need of rewiring your device.

Your MCU can be connected to a theoretical maximum of 120 devices.

detail : http://mcugear.com/en/

You can save 8 schematics (bank 0-7) on Baseboard. But this Automatic mode is you don't think about Bank but little bit slow. Manual Mode is here -> http://mbed.org/users/Info/code/MCUGearM/

How to use it?

1,include library

#include "mbed.h"

#include "MCUGearBaseA.h"
#include "MCUGearA.h"

2,Declare Module

2,Declare Module

MCUGear myModule1(p28, p27, N_***_***_***);
MCUGear myModule2(p28, p27, N_***_***_***);

myModule: Optional name for Module.

p28, p27, : I2C pins (KL25Z is "PTE0, PTE1")

N_*_*_* : Address. You can set it on the reverse side of the Module board.

3,Initialize baseboard

3,Initialize baseboard

initBase();

4,Make wiring data

4,Call wiring register

    myModule1.setWire(IO_MBED_P9, IO_REG_IN_DIR, 5);
    myModule1.setWire(IO_MBED_P15, IO_REG_OUT_DIR, 2);
    myModule1.setWire(IO_MBED_P12, IO_REG_OUT_DIR, 0);

setWire function

uint8_t setWire(uint8_t mcuIO, uint8_t direction, uint8_t moduleIO);

Set MCU's IO, Directionfrom MCU and module's IO number.

setWire() is wiring data to connect pin of MCU to pin of Module.

uint8_t mcuIO : You can choose 18 IOs.

uint8_t direction: choose signal direction IO_REG_OUT_DIR : output from MCU IO_REG_IN_DIR : input to MCU

uint8_t moduleIO: You can select module pin.

5,Open or close the module gate

5,Open or close the module gate

   myModule1.connectModule();
   ...
   (same as normal mbed code)
   ...
   myModule1.disconnectModule();


   myModule2.connectModule();
   ...
   (same as normal mbed code)
   ...
   myModule2.disconnectModule();

If you want to use many modules simultaneously as one circuit, you should use manual mode.

日本語説明

MCU Gearの自動モードライブラリです。

detail : http://mcugear.com/en/

自動モードは8つのBank設定は考えずに実行できます。同時に複数のモジュールをつなげたい場合はマニュアルモードをご利用ください -> http://mbed.org/users/Info/code/MCUGearM/

MCUGear myModule1(p28, p27, N_***_***_***);
MCUGear myModule2(p28, p27, N_***_***_***);

myModule: モジュールの好きな名前を付けられます。

setWire function

uint8_t setWire(uint8_t mcuIO, uint8_t direction, uint8_t moduleIO);

引数はマイコンのIO、マイコンからの入出力方向とモジュールの端子番号 setWire()関数はmbedの端子とモジュールの端子の割り振り方を決める関数です。

uint8_t mcuIO : mbedの18端子がアダプターボード(MCUボード)を介してベースボードに接続されています。(残りの端子はアダプターボード(MCUボード)から端子が出ています。)

uint8_t direction: mbedから見て入力か出力かを設定します。 IO_REG_OUT_DIR : output from MCU IO_REG_IN_DIR : input to MCU

uint8_t moduleIO: モジュールの出口の端子をどれにするかを決めます。

5,モジュールのゲート開閉

5,Open or close the module gate

   myModule1.connectModule();
   ...
   (same as normal mbed code)
   ...
   myModule1.disconnectModule();


   myModule2.connectModule();
   ...
   (same as normal mbed code)
   ...
   myModule2.disconnectModule();

If you want to use many modules simultaneously as one circuit, you should use manual mode. 同時に複数のモジュールに接続して動かすには
