At 120KHz, there is no echo. How can I test to determine whether it is due to an incompatible transducer or a software issue? The following is the initialization configuration:
tuss4470Write(0x10, 0x14); // Set BPF center frequency
tuss4470Write(0x16, 0xF); // Enable VDRV (not Hi-Z)
tuss4470Write(0x1A, 0x0f); // Set burst pulses to 16
tuss4470Write(0x17, 0x19);
The image is OUTA、OUTB、VOUT
