We are developing a touch panel using a microchip SAMD20 series touch MCU.
We are using MPLAB X IDE for development.
We have done tuning for touch using a data visualizer.
When giving power supply from isolated power supply our touch panel is working fine.
But when we use 7805 or non-isolated DC supply our touch is working very slow & hanging some time.
Can you help us to provide support for same to resolve issue ?
