__I2CSendCmd(_port, _i2caddr, _cmd, _result) |
Send an I2C command.
Send a command to an I2C device at the standard command register: I2C_REG_CMD. The I2C device uses the specified address.
- Parameters:
-
| _port | The port to which the I2C device is attached. See the NBC Input port constants group. You may use a constant or a variable. Constants should be used where possible to avoid blocking access to I2C devices on other ports by code running on other threads. |
| _i2caddr | The I2C device address. |
| _cmd | The command to send to the I2C device. |
| _result | A status code indicating whether the write completed successfully or not. See TCommLSCheckStatus for possible Result values. |
