Description:
|
|
By default (value '0'), the capture thread checks for the Conversion
|
|
Ready Flag to being set prior to committing a new value to the sample
|
|
buffer. This synchronizes the in-chip conversion rate with the
|
|
in-driver readout rate at the cost of an additional register read.
|
|
|
|
Writing '1' will remove the polling for the Conversion Ready Flags to
|
|
save the additional i2c transaction, which will improve the bandwidth
|
|
available for reading data. However, samples can be occasionally skipped
|
|
or repeated, depending on the beat between the capture and conversion
|
|
rates.

Description:

The value of the shunt resistor may be known only at runtime fom an
|
|
eeprom content read by a client application. This attribute allows to
|
|
set its value in ohms.
