ADVANCED COMMUNICATIONS & SENSING
ii) Continuous Fading Mode:
The GPO pin fades in and fades out continuously when the associated button is touched. The fading in and out
stops when the button is released. This is shown in Figure 38.
3.18.4 Intensity index vs PWM pulse width
Tables below are used to convert all intensity indexes parameters GpioIntensityOff, GpioIntensityOn and
GppIntensity but also to generate fading in GPO mode
During fading in(out), the index is automatically incremented(decremented) at every Inc(Dec)Time x
Inc(Dec)Factor until it reaches the programmed GpioIntensityOn(Off) value.
