Can PSoC4S communicate during CapSense scanning and processing?

[JuIn_1625121]

Hi,

The customer says that PSoC4S can't  communicate with UART during CapSense scanning and processing.

Is it right?

And, Can PSoC4S communicate with I2C during Capsense scanning and processing?

Best Regards,

Inoue

Most of the serial communication (UART, I2C) runs in hardware, requests get satisfied from a HW FIFO, filling the FIFO from a buffer is done in a small interrupt handler.

All this will run in parallel to CapSense which usually needs to get updated every 0.1 to 0.01s.
