Other Parts Discussed in Thread: TDC1000
I take the TDC7200 and TDC1000 to drive the Ultrasound sensor , but there is a problem with the TDC7200.
TDC7200 works in the measurement MODE 2 for single stop , read the TIME2 register , it can be found that when the value of TIME2 decrease to about 200- ,the value will jump to 2000+, refer to the FIG. as follows:
I have tried to set the NUM_STOP for more the stops , and read the TIMEn register value,
this jumping problem is turning cycle sitll when the TIMEn register value hit the 200- and 2000+ (dec) , the curve as below:
I make sure that the signal of Ultrasound sensor is linear , there is no jumping !
I guess there are some thing wrong with the TDC7200 setting or TIMEn register .
Need help , thank you!
