GND Ground terminal, that is, the negative

Level signal

In this chapter, all the pulse signals involved in the digital I/O function are

switched from high level to low level.

Taking pin 1 as an example, IO–1. Ps-Clear, Not-Invert contains three function

options, the first option Ps-Clear is the default function, and this function is also

a special custom function unique to this pin (the seven pins each have a differ-

ent custom function). The second and third options (Input and Output) are the

general digital I/O function, and the parameter settings and functions of the sev-

en pins are the same.

General Digital I/O Function

• Under the default condition (Not-Invert), when the pin (1 to 7) is configured

as Output, it can output the high level (False) or low level (True).

If the corresponding pin is configured as Invert, it means that the digital

signal is inverted and will output low level or high level.

• Under the default condition (Not-Invert), when the pin (1 to 7) is configured

as Output→PWM, the user needs to set the frequency (PWM Freq) and du-

ty cycle (PWM Duty) values. For example, if the PWM Freq is set to 100Hz

and the PWM Duty is set to 10%, the output waveform is as follows:
