Constructor

Parameters

[in]	sync_pin	The sync or chip select of the adc chip. Different than spi_bus_config_pin
[in]	spi_bus_config_pin	The pin that identifies the bus. More than one adc can share the same pin.
[in]	data_ready_pin	This pin tells whether the adc has finished measuring a voltage.
[in]	slot_number	This number is used to identify the chip or board. (default: 0)
[in]	reset_pin	The reset pin

Member Function Documentation

double AD7734::BytesToVoltage ( spi_utils::Message  message )

protectedvirtual

Uses chip specifications (e.g. bit resolution, registers, range) to convert a set of bytes stored in a Message object to voltage. Each ADC has its own convertion function. Check the datasheet of each chip and override the function below accordingly.

Parameters

[in]

message

Message object which stores the bytes for conversion.

Returns

The measured voltage.

Implements AdcSpi.

spi_utils::Message AD7734::ReadDataRegisterMessage ( uint8_t  channel )

protectedvirtual

Parameters

[in]

channel

The channel to be read.

Returns

Message object to read the data register.

Implements AdcSpi.

spi_utils::Message AD7734::SingleConversionModeMessage ( uint8_t  channel )

protectedvirtual

Parameters

[in]

channel

The channel to start single conversion mode on dump mode.

Returns

Message object to start single conversion mode on dump mode.

Implements AdcSpi.
