DAmoduleLPC1114

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

How to use it?

include

#include "mbed.h"

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

#include "DAmoduleLPC1114.h"

You need SPI bus, cs pin, dout1 pin and I2C bus.

bus

SPI spi(dp2, dp1, dp6); // mosi, miso, sclk
DigitalOut cs(dp25); //for SPI communications
DigitalOut Dout1(dp26);

make MCU Gear instance.

MCU Gear instance

MCUGear DAM(dp5, dp27, N_SCL_SCL_SCL);        //DA Module

make DAmodule instance.

DAmodule instance

    DAM.detectModule();    //save location data in MCUGear class.
    DAmodule myDA(spi,dp25,dp26,&DAM); //make instance for DA module

There are 2 type of DA function. These are same operation,

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

1, separately connect

        myDA.initDA(&DAM);
        DAM.connectModuleA();
        myDA.writeDAm(&DAM, data);
        DAM.disconnectModule();

2, automatically connect (same as separately connect )

1, manually connect

        myDA.writeDAa(&DAM, data);
