MAX22530-Arduino

Arduino libary for MAX22530 Please use the datasheet for additional reference to the different registers https://www.analog.com/en/products/max22530.html

Please see usage examples!

Documentation of functions:

MAX22530 example_name (10);

This is the class constructor you can give it any name you want in this case example_name, it also needs the CS (chip select) pin of the device, here the standard SPI bus is used.

MAX22530 example_name (10,&SPI);

This is the class constructor you can give it any name you want in this case example_name, it also needs the CS (chip select) pin of the device, in this case, you also pass a different SPI Class for another SPI bus (for example with stm32duino https://github.com/stm32duino/Arduino_Core_STM32/wiki/API#spi)

bool begin(int frequency);

Start the communication with the max22530 with the specified frequency max 10 MHz. The function accepts input in hertz so 1MHz is 1000000 Hz. Returns if the operation was successful.

readADC(int channel);

Reads the channel (0-3) and returns the count 0-4096 as uint16_t if value -1 read was not successful.

readFiltered(int channel);

Reads the filtered channel (0-3) and returns the count 0-4096 as uint16_t if value -1 read was not successful.

CNVTVoltage(int count);

Converts the input count to a voltage, returns a float

setComp(int channel, uint16_t up_value, uint16_t down_value, bool source, bool mode);

Sets the comparator for the selected channel, with the upper threshold (0-4096) and the lower threshold (0-4096), the source (0 -> unfiltered 1-> filtered), and the mode (0 -> digital status mode 1-> digital input mode). DIGITAL INPUT MODE DIGITAL STATUS MODE

Taken from the datasheet.

readCompReg(int channel, bool highlow);
readCompStat(void);
readInterrupt(void);

Reads the selected register and returns its value. If you read the interrupt register it is cleared

COMP STATUS

INTERRUPT STATUS

setInterruptEnable(uint16_t data);

Sets the interrupt register to enable the corresponding interrupts.

SPI_CRC (bool enable);

Enables or disables the SPI_CRC function. Default: disabled

COMTThreshold(bool enable);

For all 4 channels, the comparator thresholds from channel 1 are used. Default: disabled

CLEARFilter(int channel);

Clears the averaging filter for the specified channel

VDDF(bool enable);

Enables or disables the isolated supply voltage (1 is off) default: activated

SoftwareReset(void);

Software Reset

HardwareReset(void);

Hardware Reset

clearPOR(void);

Clears the POR (Power on Reset) bit in the 0x00 register (bit cannot be set)
