end-transmission
xod/i2c/end-transmission
Ends a transmission to a slave device initiated with `begin-transmission`. All bytes queued for writing with `write-byte` will flush at the moment of this node trigerring.
Possible errors:
— Data too long to fit in transmit buffer
— Received NACK on transmit of address
— Received NACK on transmit of data
— Other error
