Ebyte LoRa E22 power-saving WOR and structured data 12

Ebyte LoRa E22 device for Arduino, esp32 or esp8266: power-saving WOR and structured data – 5

Now we’re looking at Wake On Radio (WOR) and power-saving, one of the essential features of our E22 UART LoRa device based on popular Semtech’s SX1262, SX1268 RF chips.
Then we’ll understand how to manage complex structures that are better optimized than string format data.

Ebyte LoRa E220 LLCC68 device for Arduino, esp32 or esp8266: library – 2

Here is my tutorial on Ebyte E220 LoRa devices based on the LLCC68, very economical with a reduced consumption compared to the sx1268 and with a very wide range (from 5Km to 11Km).
Here the details of all the methods and constructors of the library.

SSD1306 OLED Display: draw images, splash and animations – 2

SSD1306 IC is used for the most commons OLED display is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons.
We will now render images and create a simple animation and take a look at the byte array generator.

SDD1306 OLED display: wiring and basic use with esp8266, esp32 and Arduino – 1

SSD1306 IC is used for the most commons OLED display is a single-chip CMOS OLED/PLED driver with controller for organic / polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons.
We are going to use it with SPI and i2c and learn the basic function.
