xuexizhong mark mark 谢谢 学习中 mark MARK 24L01 Stationary Disturbance Detection – CD
Carrier Detect (CD) is set high when an in-band RF signal is detected in RX mode,
otherwise CD is low. The internal CD signal is filtered before presented to CD
register. The internal CD signal must be high for at least 128ms.
In Enhanced ShockBurst™ it is recommended to use the Carrier Detect functionality
only when the PTX device does not succeed to get packets through, as indicated by
the MAX_RT interrupt for single packets and by the packet loss counter
(PLOS_CNT) if several packets are lost. If the PLOS_CNT in the PTX device
indicates too high rate of packet losses, the device can be configured to a PRX device
for a short time (Tstbt2a + CD-filter delay = 130ms+128ms = 258ms) to check CD. If CD
was high (jam situation), the frequency channel should be changed. If CD was low (out of range), it may continue on the same frequency channel, but perform other
adjustments. (A dummy write to the RF_CH will clear the PLOS_CNT.)
有没有人使用过上面的CD这个寄存器,为什么读出来的老是0 这个先mark之 mark mark 学习 mark!!!!!!!! 好 非常感谢 好资料,很需要 做到绝
