nordic,nrf-twim

Vendor: Nordic Semiconductor

Description

These nodes are “i2c” bus nodes.

Nordic nRF family TWIM (TWI master with EasyDMA)

Properties

Node specific properties

Base properties

Properties not inherited from the base binding file.

Name	Type	Details
zephyr,concat-buf-size	int	If concatenation buffer size is set, then multiple messages in the same direction will be concatenated into single transfers as long as there is space in buffer and no restart or stop flag is set. This property must be provided when interacting with devices like the SSD1306 display that cannot tolerate a repeated start and address appearing on the bus between message fragments. For many devices a concatenation buffer is not necessary.
sda-pin	int	SDA pin This property is required.
scl-pin	int	SCL pin This property is required.
clock-frequency	int	Initial clock frequency in Hz

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-twim” compatible.

#size-cells	int	number of size cells in reg property This property is required.
