operating current of the whole system.
In the Enhanced ShockBurstTM transceiver mode, automatic processing of NewMsg_RF24L01
prefix and CRC check code. When receiving data, automatically put the prefix and CRC check code
to remove. In data transmission, automatic prefix and CRC code, in transmit mode, set the CE is
high, at least 10us. When the sending process completed. Enhanced ShockBurstTM 4.1.1.1
launch process
A. sends the address of the receiver and the data to send into NewMsg_RF24L01 by sequence; B.
is configured for CONFIG register, so that the sending mode is sent..
C. microcontroller CE (at least 10us), Enhanced NewMsg_RF24L01 launched ShockBurstTM
launch;
NewMsg_RF24L01 Enhanced ShockBurstTM D. emission
(1) powering the RF front end;
(2) RF data package (plus prefix, CRC check code);
(3) high speed emission packet;
(4) the launch is complete and the NewMsg_RF24L01 enters the idle state.
Enhanced ShockBurstTM 4.1.1.2 reception process
A. configure the address and packet size to receive;
B. configure the CONFIG register to make it into the receiving mode, the CE set high.
After 130us NewMsg_RF24L01, C. enters the monitoring state, waiting for the arrival of the
packet;
D. when receiving a correct packet (the correct address and CRC code), NewMsg_RF2401 rf2401
automatically the prefix, address and CRC displacement;
NewMsg_RF24L01 E. notify the microcontroller by setting the RX_DR (STATUS) of the STATUS
register to the microcontroller interrupt.;
F. microcontroller to read data from the NewMsg_RF2401;
After the completion of the G. all data, you can clear the STATUS register. NewMsg_RF2401 can
enter one of the four major models.
ShockBurstTM transceiver mode
ShockBurstTM transceiver mode can be compatible with Nrf2401a, 02, E1 and E2,
NewMsg-RF2401 documents before the specific look at the company.
Idle mode
NewMsg_RF24L01 idle mode is designed to reduce the average operating current, the biggest
advantage is that, to achieve energy saving, shorten the starting time of the chip. In idle mode,
the on-chip oscillator part is still at work, the work frequency of the current with the external
crystal.
Shutdown mode
In the shutdown mode, in order to get the minimum working current, the working current at this
time is about 900nA. In the shutdown mode, the content of the configuration word is maintained
in the NewMsg_RF2401 chip, which is the difference between the mode and the power off state.
Configure NewMsg_RF24L01 module
All of the configuration of the NewMsg_RF2401 is done by SPI, with 30 bytes of configuration
word.. We recommend NewMsg_RF24L01 rf24l01 work in enhanced shockbursttm transceiver
mode. This mode, system programming will be more simple and stability will be higher, therefore,
are highlighted below the NewMsg_RF24L01 rf24l01 configuration for device configuration
method of enhanced shockbursttm transceiver mode.
