3 Serial Communication
The serial communication with the 78M6612 takes place over a UART (UART0) interface. The default
settings for the UART of the 78M6612, as implemented in this firmware, are given below:
Baud Rate: 38400bps
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: Xon/Xoff
The host’s serial interface port is required to implement these settings on its UART. To verify
communication between the host and the 78M6612, the host must send a <CR> (carriage return) to the
78M6612. Communication is verified when the 78M6612 returns a > (greater than sign) known as the
command prompt. An example is given below:
The host sends the following to the 78M6612:
<CR>
The 78M6612 sends the following back to the host:
>
Commands the host may send to the 78M6612 in order for the host to configure the 78M6612 or to
receive the measurement data are given in the next section.
