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
IQS624 mbed Component Link
IQS624 Pinout
IQS624 Connected to mbed LPC1768 board. The five wires are power(2), I2C(2) and RDY(1).
