Azoteq IQS624 Serial Terminal Display Class
Dependents: IQS624_HelloWorld Nucleo_ACM1602_I2C_DC_Angle
Library: IQSDisplayTerminal
Library for formatted display of IQS624 registers on a serial terminal
Screen Capture
Below is a screen capture of formatted output on a serial terminal program.
Note that over a million frames were captured with zero I2C errors.
IQS624 Summary
Ultra low power I2C sensor for 2D Magnetic Angle, Capacitive touch and Inductive Proximity
