EZRadio_SI4455-Library

This is an Arduino Library for using the EZRadio SI4455 Wireless Tranciever Chip with the NodeMCU/ESP8266. The library enables users to initialize and configure the Radio Chip to either transmit or recieve data. For more details, please do refer the EZRadio SI4455 Application Guide by Silicon Labs. The following library was ported from the example projects generated by WDS.

The radio configuration file was generated using WDS 3.2.11.0. The below is the main configuration parameters that is supported by the configuration file -->

  1. Base Frequency : 433 MHz
  2. GPIO 0 : INPUT - Pull Up Disabled
  3. GPIO 1 : RX_DATA

Below is connections between the NodeMCU and EZRadio SI4455
