help
Maximum command size in bytes. One byte is reserved for the string
terminator character.
config SHELL_PRINTF_BUFF_SIZE
int "Shell print buffer size"
default 30
help
Maximum text buffer size for fprintf function.
It is working like stdio buffering in Linux systems
to limit number of peripheral access calls.
config SHELL_ARGC_MAX
int "Maximum arguments in shell command"
default 12
help
Maximum number of arguments that can build a command.
If command is composed of more than defined, argument SHELL_ARGC_MAX
