|
|
* \brief
|
|
* Provides APIs for transmitting messages to or from the board via standard
|
|
* printf/scanf functions. Messages are transmitted over a UART connection which
|
|
* is generally connected to a host machine. Transmission is done at 115200 baud
|
|
* using the tx and rx pins provided by the user of this library. The UART
|
|
* instance is made available via cy_retarget_io_uart_obj in case any changes
|
|
* to the default configuration are desired.
|
|
* NOTE: If the application is built using newlib-nano, by default, floating
|
|
* point format strings (%f) are not supported. To enable this support you must
|
|
* add '-u _printf_float' to the linker command line.
