Shockbursttm configuration word make NewMsg_RF24L01 rf24l01 to deal with RF protocol, after

configuration is complete, in the process of NewMsg_RF24L01 rf24l01, only need to change the

contents in the lowest one byte, the receiving and sending mode switch between.

ShockBurstTM configuration word can be divided into the following four parts:

Data width: the number of data occupied in the radio frequency packet. This allows the

NewMsg_RF24L01 to distinguish between the received packet data and the CRC code;

Address width: the number of addresses in the radio frequency packet. This allows the

NewMsg_RF24L01 to distinguish between address and data;

Address: the address of the receiving data, the address of the channel 0 to the channel 5;

CRC: enable CRC to generate NewMsg_RF24L01 verification code and decoding. When using the

CRC technology within the NewMsg_RF24L01 chip, make sure that the CRC check is enabled in

the configuration word (EN_CRC CONFIG), and send and receive the same protocol. The bit

description of the CONFIG register of the NewMsg_RF24L01 configuration word is shown below.
