Installing PADI to Arduino IDE

Daniil Zhuk
The PADI IoT Stamp module is a newly emerging alternative to the already well-known ESP8266, with much more interesting features.

Connecting to PADI via GPIO

Daniil Zhuk
Like almost all microcontrollers, PADI has general-purpose I / O pins (GPIO). They can be used for direct connection of sensors or other actuating devices, as well as for connecting several microcontrollers to the network using various interfaces displayed on the pins.

Connecting to PADI via SPI

Daniil Zhuk
Modern microcontrollers and single-chip systems have many interfaces for communicating with peripheral devices. One of them, the easiest to implement - SPI or Serial Peripheral Interface - allows you to transfer data in two directions simultaneously over a single clock signal, that is, it is full-duplex.

Connection to PADI via I2C interface

Daniil Zhuk
The I2C interface, Inter-Integrated Circuit, was developed by Philips to connect devices within a single device. Now it is used everywhere for "communication" of the microcontroller and the periphery or equally equivalent controllers due to the small number of wires (2 in total) and relatively high speeds.

Connection to PADI via UART interface

Daniil Zhuk
The UART interface is one of the first external computer interfaces that was already used in the first self-assembled computers as a COM port (RS232, is still in use). It would be strange if PADI did not have at least one such interface, and it has as many as 3!
