arduino uno and esp32s to lora sx1272 pinout connections and SPI communication codes

Lora-SX127x-ESP32s-Arduino-Transceiver-Arduino-IDE-Code

*In this project, I communicate two Arduino or two ESP32s with using SX1272MB2DAS semtech shield Transceivers. Modules and modules's pinouts have been given in this repo. *You can use this library not only sx1272 but also SX1261, SX1262, SX1268, SX1273, SX1276, SX1277, SX1278, SX1279, SX1280, SX1281, SX1282, RF69, RFM22, RFM23, RFM95, RFM96, RFM97, RFM98 and many other wireless modules. However, you have to rearrange pin connections.

*Also, you can use these codes for many other microcontrollers such as Teensy, STM32.

*I wrote these arduino codes with using universal wireless communication library for Arduino

Plus, I added the library as a zip file in this repository.
