Ebyte LoRa E32 device for Arduino, esp32 or esp8266: configuration – Part 3
Here is a tutorial on the E32 LoRa (Long Range) device’s very cheap and long-range (from 3Km to 8Km).
It’s time to understand the configuration.

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: library – 2
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
Here my library to simplify the complex usage.
PCF8575 i2c 16 bit digital I/O expander
Library to use i2c pcf8575 IC with arduino and esp8266.
This IC can control (until 16) digital devices like button or led with 2 only pins.
Can read and write digital value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
PCF8574 i2c digital I/O expander: Arduino, esp8266 and esp32, basic I/O and interrupt – Part 1
Library to use i2c pcf8574 IC with arduino and esp8266.
This IC can control (until 8) digital devices like button or led with 2 only pins.
Can read and write digital value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
