iic - I2C generic i/o device driver
.Cd "device iic"
The iic character device driver provides generic i/o to any iicbus(4) instance. In order to control I2C devices, use /dev/iic? with the following ioctls:
| Ioctl Description |
I2CSTART "send start condition to the specified device (with 7-bit address) on the bus"
I2CSTOP "send stop condition to the bus"
I2CRSTCARD "reset the bus"
| || |
You may also use read/write routines, then I2C start/stop handshake is managed by the iicbus system.
