Description
The RX_PW_Pn registers are used to set the payload widths for each Rx pipe.
Contents
This table is copied from the nRF24L01 product specification (page 56). Each of the registers, RX_PW_P0 through RX_PW_P5, have the same format. The RX_PW_P0 register is shown below:
| Name |
Bit |
Reset Value |
Type | Description |
| Reserved | 7:6 | 00 | R/W | Only ’00’ allowed |
| RX_PW_P0 | 5:0 | 000000 | R/W | Number of bytes in RX payload in data pipe 0 (1 to 32 bytes). 0 = Pipe not used 1 = 1 byte … 32 = 32 bytes |
Comments
This configures the static payload widths. There is an option to use dynamic payload widths, in which the radio calculates the payload width as it receives a packet. This project uses static payload widths exclusively.
The firmware default for all pipes is 0, even for the pipes that are enabled by default (0 and 1).
