Register display for Azoteq IQS621 ultra low power I2C multi-function sensor.
A library that performs a register dump of the Azoteq IQS621 ultra low power multisensor registers.
More information on the IQS621 here:
Azoteq IQS621 ultra low power sensor for ambient light, magnetic field, capacitance and inductive proximity. Empowers next-generation user interfaces.
Low Cost Evaluation Board For Azoteq IQS621ultra low power I2C sensor for ambient light, magnetic field, capacitance, inductive proximity and temperature.
Serial Terminal Output
IQS621 Register display as performed by mbed LPC1768.
Note the frame number - over half a million register dumps were performed with zero I2C errors.
