Tool/software:
I am from Secure Meters.(Hardware Team)
In the uploaded PCB design with MSP430FR6045, I have implemented a separate ground plane for the Ultrasonic Sensor (USS) section. This ground is then connected to the local/common ground through 0 OHM Link.I would like to confirm whether it is necessary to maintain a separate ground for the USS sensor section, or if a single common ground shared between the MSP430FR6045 and the USS sensor section is recommended
This approach seems to be affecting the measurement accuracy. I would like to know which method is recommended for best performance: maintaining a separate ground for the USS section, or using a common ground shared between the MSP430FR6045 and the USS sensor section.”
