Master Transmit Message
This command causes iPort/AFM to write the specified data bytes to the currently
selected Destination I2C Slave Address with or without generating an I2C Stop
condition after the last byte is transmitted.
Enter Message Bytes (0 or more Printable ASCII or Hex-equivalent ~00..~FF), then
Press Enter, ESCape to Cancel.
Note: The tilde (~) character and the Carriage Return (CR) character are used as
special marker characters within all iPort/AFM transmit text messages. These
characters may not be used within the text of a message, but must be replaced by the
following "Hex-equivalent" characters:
Tilde replaced by "~7E"
Carriage Return replaced by "~0D"
iPort/AFM automatically translates "Hex equivalent" characters to their single-byte
value for transmission across the I2C Bus.
All entered data bytes are transmitted to the Destination I2C Slave Receiver device.
Master Transmit stops upon receiving the first negative acknowledgment (Nack)
from the Slave Receiver. If not disabled, the message is then terminated with an I2C
Stop condition.
Sending Master Transmit messages with No Stop allows the Master to retain
exclusive control of the I2C Bus until it finally sends a Stop. During this time, the
Master can send additional (Repeated Start) Master Transmit or Master Receive
messages to the same or other I2C Slave devices.
