PROTOCOLS
Device
Defined in fuchsia.hardware.i2cimpl/i2cimpl.fidl
Low-level protocol for i2c drivers.
GetMaxTransferSize
Request
<EMPTY>
Response
| Name | Type |
|---|---|
payload | Device_GetMaxTransferSize_Result |
SetBitrate
Sets the bitrate for the i2c bus in KHz units.
Request
| Name | Type |
|---|---|
bitrate | uint32 |
Response
| Name | Type |
|---|---|
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.
