This library is for MCU Gear 12bit AD 2ch module with LPC1114FN28. You do not need thik about wiring to AD 2ch module. It contain wiring setting function.

http://www.mcugear.com/en/

How to use it?

#include "mbed.h"

#include "MCUGearBaseALPC1114.h"
#include "MCUGearALPC1114.h"
#include "commonALPC1114.h"

#include "AD2chModuleLPC1114.h"

You need SPI bus, cs pin and I2C bus.

SPI spi(dp2, dp1, dp6); // mosi, miso, sclk
DigitalOut cs(dp25); //for SPI communications

make MCU Gear instance.

MCUGear AD2(dp5, dp27, N_SCL_SCL_VSS);        //AD 2ch Module

Save location data in the instance.

    AD2.detectModule();    //save location data in MCUGear class.

make ADmodule instance.

    AD2chModule myAD2(spi,dp25,&AD2); //make instance for AD module

There are 2 type of AD function. These are similar operation,

1, separately connect (you can check the operation separately.)

        myAD2.initAD2ch(&AD2);
        AD2.connectModuleA();
        data = myAD2.readADm(&AD2, 0); //0ch
        pc.printf("AD 0ch = %d  ",data);
        data = myAD2.readADm(&AD2, 1); //1ch
        pc.printf("AD 1ch = %d\r\n",data);
        AD2.disconnectModule();

2, automatically connect (It is similar to separately connection but little bit slow. )

        data = myAD2.readADa(&AD2,0); //0ch
        pc.printf("AD 0ch = %d  ",data);
        data = myAD2.readADa(&AD2,1); //1ch
        pc.printf("AD 1ch = %d\r\n",data);

The sample progarm is here.

#include "MCUGearBaseALPC1114.h"
#include "MCUGearALPC1114.h"
#include "commonALPC1114.h"

Serial pc(dp16, dp15); // tx, rx Set BaudRate = 115200 in main()
SPI spi(dp2, dp1, dp6); // mosi, miso, sclk
DigitalOut cs(dp25); //for SPI communications

MCUGear AD2(dp5, dp27, N_SCL_SCL_VSS);        //AD 2ch Module

//output pins = P0_3, P0_7, P0_11, P1_0, P1_1, P1_2, P1_4, P1_5

DigitalOut Dout8(dp15);

//inputpins = P1_8, P1_9
DigitalIn Din1(dp17);

int main() {
    
    pc.printf("Hello World!\r\n");
        
    wait(1);
    
    initBase(); //initialize Baseboard
    
    AD2.detectModule();    //save location data in MCUGear class.
    AD2chModule myAD2(spi,dp25,&AD2); //make instance for AD module
    
    int data = 0;
    
    while(1) {
/*
        //manually connect      
        myAD2.initAD2ch(&AD2);
        AD2.connectModuleA();
        data = myAD2.readADm(&AD2, 0);
        pc.printf("AD 0ch = %d  ",data);
        data = myAD2.readADm(&AD2, 1);
        pc.printf("AD 1ch = %d\r\n",data);
        AD2.disconnectModule();
*/        
        //automatically connect
        data = myAD2.readADa(&AD2,0);  //0ch
        pc.printf("AD 0ch = %d  ",data);
        data = myAD2.readADa(&AD2,1);   //1ch
        pc.printf("AD 1ch = %d\r\n",data);
        
        wait(0.5);

    }
}

このライブラリはMCU Gear の12bit AD 2ch モジュールをLPC1114で使用する場合のライブラリです。 ライブラリの中に配線情報が入っているため、回路に差し込むだけで簡単に使用できます。

使い方

#include "mbed.h"

#include "MCUGearBaseALPC1114.h"
#include "MCUGearALPC1114.h"
#include "commonALPC1114.h"

#include "AD2chModuleLPC1114.h"

SPI、cs, I2Cを準備します。

SPI spi(dp2, dp1, dp6); // mosi, miso, sclk
DigitalOut cs(dp25); //for SPI communications

MCU Gear のインスタンスを作ります。

MCUGear AD2(dp5, dp27, N_SCL_SCL_VSS);        //AD 2ch Module

次に接続位置を保存します。

    AD2.detectModule();    //save location data in MCUGear class.

DAモジュール のインスタンスを作り先ほどのインスタンスに渡します。

    AD2chModule myAD2(spi,dp25,&AD2); //make instance for AD module

ライブラリには２つの種類がありますが、処理をバラバラに行いたい場合と、まとめて一行で行いたい場合とで使い分けてください。 結果は同じものです。

1, separately connect (you can check the operation separately.)

        myAD2.initAD2ch(&AD2);
        AD2.connectModuleA();
        data = myAD2.readADm(&AD2, 0); //0ch
        pc.printf("AD 0ch = %d  ",data);
        data = myAD2.readADm(&AD2, 1); //1ch
        pc.printf("AD 1ch = %d\r\n",data);
        AD2.disconnectModule();

2, automatically connect (same as separately connect )

        data = myAD2.readADa(&AD2,0); //0ch
        pc.printf("AD 0ch = %d  ",data);
        data = myAD2.readADa(&AD2,1); //1ch
        pc.printf("AD 1ch = %d\r\n",data);
