Tool/software:
Now I am using the TX7332 chip to complete the design of ultrasonic driver.
but in the test, I found that under the condition of using the default power mode, TR_BF_SYNC signal of 100Hz, I can only capture echo signals in channels 9-16 and 25-32 of RX, and all OUT channels have driver signals.
I suspect it is the problem of TR_EN1 and TR_EN3 signals, but after consulting the manual, the TR_EN1 and TR_EN3 signals only need to be pulled down in the default power mode, I have tried but there is no effect, how should I solve this problem?
I would appreciate it if anyone would answer this question, which has puzzled me for a long time.
Input voltage: ±75V, 1.8V logic
