Dear Expert ，
Good day!
Our customer use the FR2433 chip to connect the capture pin to the PWM waveform, but the data parsed in the interrupt is different from the data displayed by the oscilloscope. Please help verify whether there is an abnormality in the analysis of the capture timer data in the code? thanks. What we captured is the us level data, the clock configuration is 16Mhz, but we have the following two uncertain factors about the configuration, please help to confirm first:
1. Whether the 16Mhz configuration configured by smclk is normal, please check the sys_cs_init interface of the main function for details.
2. Check whether the elapsedTime parameter calculation method in the capture interrupt is correct. This parameter calculates the duration of the low level, the unit is us.
Please refer to the attachment for the specific project code.
Thanks.
BR,
Leon.liu
