PROTOCOLS

Device

Defined in fuchsia.hardware.i2cimpl/i2cimpl.fidl

Low-level protocol for i2c drivers.

GetMaxTransferSize

Request

<EMPTY>

Response

NameType
payload Device_GetMaxTransferSize_Result

SetBitrate

Sets the bitrate for the i2c bus in KHz units.

Request

NameType
bitrate uint32

Response

NameType
payload Device_SetBitrate_Result

Transact

|Transact| assumes that write ops write_data length are not zero. |Transact| assumes that at least the last op has stop set to true.

For each read-transaction, there will be a corresponding ReadData returned. Write-transactions produce no data result.

Request

NameType
op vector<I2cImplOp>:256

Response

NameType
payload Device_Transact_Result
