Introduction

This library implements a complete interface to the Maxim MAX1464 Multichannel Sensor Signal Processor for Arduino.

There are two classes provided with this library. The MAX1464 class makes use of Arduino's SPI library, whereas the MAX1464_SS class implements SPI in software on the user-specified pins. See the documentation for a complete reference.

Tutorial

To use the library, include the header file:

#include <MAX1464.h>

#include <MAX1464_SS.h>

if you prefer to use software SPI.

Define a macro for the slave select pin:

#define SPI_SLAVESELECT 10

If you are using software SPI, you also need to define the pins for MOSI, MISO and SCK:

#define SPI_DATAOUT 11  // MOSI
#define SPI_DATAIN  12  // MISO
#define SPI_CLOCK   13  // SCK

In case you need to use register addresses, configuration bits, etc, add this line to access the corresponding enums easily:

using namespace MAX1464_enums;

Then, create an instance of the MAX1464 or MAX1464_SS class:

MAX1464 max1464(SPI_SLAVESELECT);

MAX1464_SS max1464(SPI_SLAVESELECT); // for software SPI

In your setup() function, call the begin() method:

max1464.begin();

For software SPI:

max1464.setSpiPins(SPI_DATAOUT, SPI_DATAIN, SPI_CLOCK); // for software SPI only
max1464.begin();

Now the library is initialized and you can use it in your loop() function.

Common operations

To control the CPU state:

max1464.haltCpu();
max1464.resetCpu();
max1464.releaseCpu();

To write to and read from CPU ports:

max1464.writeCpuPort(0x1234, CPU_PORT_A);
uint16_t value = max1464.readCpuPort(CPU_PORT_A);

To write to and read from module registers:

max1464.writeModuleRegister(
            CONFIGA_PGA_00 | CONFIGA_CLK6 | CONFIGA_RES_9BIT | CONFIGA_CO0,
            R_ADC_CONFIG_1A);
max1464.writeModuleRegister(GPIO_OUT_HIGH, GPIO1_CONTROL);
uint16_t value = max1464.readModuleRegister(GPIO1_CONTROL);

Please refer to the documentation for a complete list of available enums.

To write to flash memory:

max1464.beginWritingToFlashPartition(PARTITION_0);
max1464.writeHexLineToFlashMemory(inputString); // HEX line 1
max1464.writeHexLineToFlashMemory(inputString); // HEX line 2
...

Example

The library comes with an example Arduino sketch implementing a serial terminal. This is a list of the serial commands available in the example:

IDEN print an identification string
RFW [N] read firmware (partition N)
HALTCPU
RESETCPU
RELEASECPU
RP N read CPU port number N (0-15)
STEP single step the CPU, useful for debugging
!ERASEFLASHMEMORY! (both partitions)
!WRITEFLASHMEMORY! enter firmware flashing mode. From now on, only HEX lines are expected from the serial port. You can then send a whole HEX file using your terminal emulator. Normal command mode is resumed after the last HEX line has been sent, or alternatively by issuing the !ABORTWRITEFLASHMEMORY! command.
!ABORTWRITEFLASHMEMORY! see above
