基于ARM和nRF24L01的无线数据传输系统当发送端nRF24L0l配置成PTX模式时，配置nRF24L01工作在后一种发送模式下，重新发送的等待时间为250μs，重新发送次数为10次，地址是TX_AW，输出功率为0 dBm，速度为2 Mb／s，并且使能发送完成和重发送次数超限两种中断，CRC校验位为2字节，nRF24L01处于POWER_UP状态。函数中WRITE_REG为写命令基地址0x20。-ARM and nRF24L01 based wireless data transmission system configured as the sending end nRF24L0l PTX mode, the configuration nRF24L01 work in the latter sending mode, re-send the waiting time for 250μs, re-send the number to 10, the address is TX_AW, output power of 0 dBm, speed of 2 Mb/s, and so can send unlimited number of times to complete and re-send the two interrupt, CRC parity bit to 2 bytes, nRF24L01 in POWER_UP state. Function WRITE_REG write command for the base address 0x20.
