char aI2C_ReadChar(

char addr, char reg);

Parameters:

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

Return Value:

A char with the contents of the desired register in an I2C device.

Description:

This routine reads a 1-byte char value at the specified address in 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:

n = aI2C_ReadChar((unsigned char)0xC0,5);

This would set variable n to the contents of register 5 in an I2C device with an address of 0xC0 (192).
