AdKey control mode

The ADKEY key control method We use the AD button method, replacing the traditional matrix keyboard connection method. The advantage of this is that the MCU has full and more powerful AD function. The design is simple and not simple. The module is configured with 2 AD ports and the resistance value of 10 keys.


MCU front -line serial control

The N9105 supports a single -chip microcomputer simulation of the first -line serial control. This control method is simple and convenient, suitable for any single -chip microcomputer.
