Grr,
Yeah, in Nuttx, fgets, fgetc, etc. don't echo. Even in Linux, the echo
is actually a function of the terminal, not the running program and
'fgets'.
In Nuittx, use the readline routine instead. But keep in mind that
readline is only *inspired* by GNU readline and has different calling
parameters (you also have to ensure it is enabled / configured in 'make
menuconfig':
#include <system/readline.h>
my_get_command(struct spitest_s *spitest)
{
char input[80];
ssize_t len = 0;
while (len == 0)
{
printf("\nEnter Command:");
fflush(stdout);
len = readline(input, sizeof(input), stdin, stdout);
if (len)
{
spitest->cmd = input[0]; /* First char is the command */
...
}
}
...
}

Hello
That fflush is for fgets
Yes, with a stdout flush, message prints but the question remains about why
is it needed and how can I get input echo
Thanks

Hey Grr,
You need the fflush(stdout) call to be *after* the printf("\nEnter
Command:").
If the printf doesn't end with \n, then the stdout won't be flushed.

Hello to all
Is there a way to get stdout without a LF?
I have something like
case INPUT_CMD:
fflush(stdin);
printf("\nEnter Command:");
fgets(input, INPUT_STRING, stdin);
spitest.cmd = input[0]; /* First char is the command
*/
that in Linux prints message and waits for input but in Nuttx shows
nothing.
I don't want LF because that destroys the format I want for program
interface
Another related issue is I don't get echo from input
How do I get messages printed without a LF and echo from input?
TIA
