I am designing TIDA-01486 to get better signal from 1 pair of piezo transducer on metal pipe (clamp on application). Following the below thread:
I have downloaded the updated software to control PD1 and PD2. We are not using MUX/Analog switch in our design therefore we do not need S1,S2, S3 and S4. Our plan is to first cross verify, is the updated software working fine and we want to see PD1 and PD2 should toggle from 0 to 1 or vise versa. I also managed to create new image file by replacing the 4 files (hal_system.c, hal_system.h, hmi.c and hmi.h) from updated software. Flashing has been done perfectly fine but I could not see toggling of PD1 and PD2, it is only a sinusoidal wave even without powering the EMV430-FR6047. I should suppose to see digital signal 1 or 0 on PD1 and PD2.
Please let me correct if I am wrong, I am connecting the oscilloscope probe on connector J6 pin 16 for PD1 and connector J5 pin 9 for PD2.
