RTD120D-EVK Evaluation Kit Software Manual
Text commands are simple, one-line strings that are terminated by a carriage return. These commands can be
used to interrogate and stream data from the board and to perform various functions. An example of a text
command is “
=ppm
<CR>”. Note that the <CR> is a single carriage return character, so you just need to type
=ppm
and then press
Enter
on the keyboard. A terminal program, such as
Putty
or
Tera Term
, can be used to
interact with the EVK in this mode. In order to allow strings of characters to be pasted into such a terminal
program without any data loss, Renesas recommends to configure a 5 millisecond delay between sent characters
in the terminal program’s settings. For example, in Tera Term, the following setup works reliably when pasting text
into the terminal window (MENU: Setup - Serial Port...)
Terminal mode does not echo characters as they are received. This is to make it easier to write host applications
that use the terminal mode, without having to distinguish between echoed characters and information responses.
As such, to make it easier to type interactively when using a terminal program, you may find it preferable to enable
“local echo” in the terminal program’s configuration settings. In Tera Term, this is how it is (MENU: Setup -
Terminal...)
