Formatted text over serial
Hello all
Is there a way to have formatted text output over serial? I want to create
some testing utility that runs from nsh and has some screen organization to
ease use
I tested pdcurses examples but they seem to depend on fb (haven't analyzed
code) and all exited or crashed with "initscr(): Unable to create SP"
Is there a builtin way to do such thing?
TIA

Sure, no problem!
Looking at the code, someone along the way changed the first calling
parameter in that function from "FAR SCREEN *sp" to "FAR SCREEN *s". In
my older copy of the NuttX code, the first parameter is "FAR SCREEN *sp".
Since I know the code pretty well, I can pull down the Apache NuttX head
and try to compile it.

Hey Greg,
I actully tried ALL of the emulation modes offered by minicom and each
one behaved the same.
I found that using Linux 'screen' or 'tmux' works, but neither of those
deal with the /dev/tty device "disappearing" suddenly.

Hey Johnny,
It has been a while since I ran the pdcurses with minicom, but my
recollection is that something sets attributes of the entire display to
blink all the time. Plus when drawing window borders using the VT100 /
ANSI line drawing character, you end up with a bunch of funky characters
intsead of the nice "| ┌ ┐ └ ┘" characters.

Not only everything blinks but the background color changes to some middle
scale gray and that happens with all pdcurses demos
But that's minicom. I just tested with screen and they work just fine,
color included
I kind of remember now minicom had such problems with curses 15+ years
back. It seems it's not a bug, it's a feature

But using tmux, I am able to get pdcurses displays like this (it
actually has color):

The VT102 is a superset of the VT100. There are a couple of additional
functions the VT102 have, as well as by standard having a few options
installed that were optional on the VT100.
With that said, I'm not sure what is meant by "flashing mode" here. Is
there some flashing effect with redrawing things, or are we talking
about the flashing attribute of characters, by which they blink all the
time?

If you start mincom with -t vt100 it should force VT100 vs VT102 mode.
But I thought that VT102 was mostly compatible?
Re: Formatted text over serial

Yeah, I have never found a way to use pdcurses with minicom ... it
always has flashing characters like you stated.

It also needs CONFIG_PDCURSES_MULTITHREAD or there's no PDC_ctx_free()
definition
Now examples compile and work although in flashing mode with minicom in
VT102 mode
I'll fix that later
Thanks again

Looks like changing nuttx/pdcdisp.c:840 from "sp" to just "s" was the
only compile error. Though going through the exercise made me remember
that you also need to select:
Application Configuration --> Graphics Support --> pdcurses --> Input
Devices --> Terminal Input
Otherwise you don't have any input device for pdcurses.

Thank you for your response
I searched menuconfig according to your instructions and found it.
Compilation crashed with
nuttx/pdcdisp.c:840:19: error: 'sp' undeclared (first use in this
function); did you mean 's'?
but it's a matter of debugging it. Maybe a lacking option, I'll research it

Grr,
Actually, pdcurses has a mode that will work over serial using
System->Termcurses. This is a terminal based extension to pdcurses that
I added a few years back. It supports VT-100 / ANSI escape codes. I
haven't tested it in the Apache NuttX framework to validate it still
works though.
If you don't define CONFIG_SYSTEM_TERMCURSES, then yes, you will get an
error about the graphic fb creation.
