Transmitting Data via the I²C Interface
The user can implement these functions in order to read and write to
devices connected to the I²C interface.
Caution:
The I²C-EEPROM, found on the Grabber card, is protected against
accidental writing. Therefore, access to the device address space 0xA0
to 0xA3 is not allowed.
In order to obtain access to the internal EEPROM memory space,
please use the appropriate special functions.
void I2C_Set_BR_Mode (WORD nDevNo, BYTE bMode)
bMode
baudrate
pciGrabber-4x4: 0 = 99,2 kHz, 1 = 396,8 kHz
This function determines the baud rate for transmission on the I²C bus.
A lower or a higher transmission rate can be selected.
