Wire (I2C)

(inherits from Stream)

This object allows you to communicate with I2C / TWI (Two Wire Interface) devices. For an in-depth tutorial on I2C, see learn more about I2C.

Interface	Maximum Speed (Gen2)	Maximum Speed (Gen 3)	Maximum Peripheral Devices
UART Serial	230 Kbit/sec	1 Mbit/sec	1 (point-to-point)
I2C	400 Kbit/sec	400 Kbit/sec	Many (limited by addresses)
SPI	60 Mbit/sec	32 Mbit/sec	Many (limited by CS GPIO pins)

Since 6.4.0:

System.sleep() can be called from PRE_STARTUP() in Device OS 6.4.0 and later, and in STARTUP() in all versions of Device OS.
