Communications Class Device for USB

This capsule allows Tock to support a serial port over USB.

Structs§

  • CdcAcm
    Implementation of the Abstract Control Model (ACM) for the Communications Class Device (CDC) over USB.

Constants§

  • CDC_BUFFER_TIMEOUT_MS
    Number of ms to buffer uart transmissions before beginning to drop them. This is useful in that it allows users time to connect over CDC without losing message, while still guaranteeing that blocking uart transmissions eventually get a callback even if a debug output is not connected.
  • MAX_CTRL_PACKET_SIZE_EARLGREY
    Platform-specific packet length for the earlgrey USB hardware.
  • MAX_CTRL_PACKET_SIZE_NRF52840
    Platform-specific packet length for the nRF52 USB hardware.
  • MAX_CTRL_PACKET_SIZE_SAM4L
    Platform-specific packet length for the SAM4L USB hardware.
