/***************************************************************************//** * \file cy_retarget_io.h * * \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. * ******************************************************************************** * \copyright * Copyright 2018-2019 Cypress Semiconductor Corporation * SPDX-License-Identifier: Apache-2.0 * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. *******************************************************************************/ #pragma once #include #include "cy_result.h" #include "cy_pdl.h" #if defined(__cplusplus) extern "C" { #endif /** UART baud rate */ #define CY_RETARGET_IO_BAUDRATE (115200) /** Defining this macro enables conversion of line feed (LF) into carriage * return followed by line feed (CR & LF) on the output direction (STDOUT).
