CONFIG_NEWLIB_STDOUT_LINE_ENDING
Line ending for UART output
Found in: Component config > Newlib
This option allows configuring the desired line endings sent to UART when a newline (‘n’, LF) appears
on stdout. Three options are possible:
CRLF: whenever LF is encountered, prepend it with CR
LF: no modification is applied, stdout is sent as is
CR: each occurence of LF is replaced with CR
This option doesn’t affect behavior of the UART driver (drivers/uart.h).
Available options:
• CRLF (NEWLIB_STDOUT_LINE_ENDING_CRLF)
• LF (NEWLIB_STDOUT_LINE_ENDING_LF)
• CR (NEWLIB_STDOUT_LINE_ENDING_CR)
CONFIG_NEWLIB_STDIN_LINE_ENDING
Line ending for UART input
Found in: Component config > Newlib
This option allows configuring which input sequence on UART produces a newline (‘n’, LF) on stdin.
Three options are possible:
CRLF: CRLF is converted to LF
LF: no modification is applied, input is sent to stdin as is
CR: each occurence of CR is replaced with LF
This option doesn’t affect behavior of the UART driver (drivers/uart.h).
Available options:
• CRLF (NEWLIB_STDIN_LINE_ENDING_CRLF)
• LF (NEWLIB_STDIN_LINE_ENDING_LF)
• CR (NEWLIB_STDIN_LINE_ENDING_CR)
