CONFIG_FXOS8700_PULSE_WIND¶
Pulse window
Type: hex
Help¶
The maximum interval of time that can elapse after the end of the latency interval in which the start of the second pulse event must be detected provided the device has been configured for double pulse detection. The detected second pulse width must be shorter than the time limit constraint specified by the PULSE_TMLT register, but the end of the double pulse need not finish within the time specified by the PULSE_WIND register. The resolution depends upon the sample rate (ODR) and the high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and pls_hpf_en=0, the resolution is 1.25 ms/LSB.
