3.6.2.2.1 pcComLayer

This layer has two circular buffers: one to transmit data to the PC and another to receive data from the PC. A set of APIs accesses the circular buffers and can be used to write or read from both Transmit buffers. The pcComm layer is not used in CAPBridge mode.

The pcComm layer is accessed by:

  • USB/BLE layer to:
    • Write data to RX buffer
    • Read data to TX buffer
  • Touch process (or Bypass mode) to:
    • Write data to TX buffer
    • Read data to RX buffer

TX and RX terms are related to MCU.
