====== I2Cwrite( ) ======

''variable = I2CWrite(data)''
| //variable// | Acknowledge (0=Acknowledgment, 1=No Acknowledgment)  |
| //data// | data to send (Byte value : 0 to 255)   |

Sends one byte of data through I2C. This command creates an ACK pulse
and returns 0 if there is an acknowledgment and 1 if there isn’t. No
acknowledgment indicates that there was a communication error (possibly
due to incorrect wiring). The following is an example illustrating how this
can be used to trigger an error processing function:


<code xbasic>
If I2CWrite(DATA)=1 Then GoTo ERR_PROC
</code>

If you don’t need to check for an ACK, you can just use any variable to
receive the ACK status as shown below:


<code xbasic>
A = I2CWrite(DATA)
</code>

One byte of data transfer takes approximately 60 microseconds.
Please refer to Chapter 8 "About I2C…" for a detailed description of I2C
communications.
