shirish47 / Gray code in Arduino
Created December 17, 2015 11:19
This is simple implementation of Gray to binary and Binary to Gray for a single Byte of Data.
uint8_t Binary2Gray(uint8_t data)
{
int n_data=(data>>1);
n_data=(data ^ n_data);
return n_data;
}
uint8_t Gray2Binary(uint8_t data)
{
byte b[8]={0,0,0,0,0,0,0,0};

TMRh20 2014 - Updates to the library allow sleeping both in TX and RX modes:
TX Mode: The radio can be powered down (.9uA current) and the Arduino slept using the watchdog timer
RX Mode: The radio can be left in standby mode (22uA current) and the Arduino slept using an interrupt pin
