The Device Control Library provides the ability to configure and control an XMOS device from a host over a number of transport layers.
- Simple read/write API
- Fully acknowledged protocol
- Includes different transports including I2C slave, USB requests, xSCOPE over xCONNECT and SPI slave
- Supports multiple resources per task
The table below shows combinations of host and transport mechanisms that are currently supported. Adding new transport layers and/or hosts is straightforward where the hardware supports it.
| Host | I2C | USB | xSCOPE | SPI |
|---|---|---|---|---|
| PC / Windows | Yes | Yes | ||
| PC / OSX | Yes | Yes | ||
| Raspberry Pi / Linux | Yes | TBD | Yes | |
| xCORE | Yes |
Less than 1KB of code space is needed for the target device, plus whatever the chosen transport layer library requires. The API is in the form of function calls, so no additional logical cores are consumed. I/O requirements also depend on which transport layer is used.
