#include <aI2C.tea>




void aI2C_WriteChar(

char addr, char reg, char data);

Parameters:

addr	-	The address of the I2C device.
reg	-	The register to be written.
data	-	The data to be written.

Return Value:

This routine does not return a value.

Description:

This routine writes a byte to an I2C device.  The device must use single-byte register addresses.  The IIC baud rate may need to be lowered to achieve reliable communication with the I2C device.  See the cmdVAL_SET or aPortIICBaud documentation for details.

Example:

aI2C_WriteChar((unsigned char)0xC0, 5, 45);


This would write a byte with a value of 45 to register 5 in an I2C device with an address of 0xC0 (192).
