probe_rs232c.c

ST32F10xxx+uCOSII2.85的官方源代码,带LCD驱动,支持Keil3和IAR环境.这个可以做为参考,实际使用需要修改,他做的太复杂了,目录也很深

*                       Initialize COM port for uC/Probe RS-232 Communication Module
*
* Description: Initialize the UART for uC/Probe communication.
*
* Argument(s): baud_rate    is intended baud rate of the RS-232.
*
* Returns    : None
*
* Note(s)    : (1) The following constants control the GPIO remap for the USART control lines:
*
*                       PROBE_RS232_UART_1_REMAP
*                       PROBE_RS232_UART_2_REMAP
*                       PROBE_RS232_UART_3_REMAP_PARTIAL
*                       PROBE_RS232_UART_3_REMAP_FULL
*
*                   Though the #error directives in "Local Configuration Errors" will require that
*                   all are defined, the value of those bearing on the USART not used will have no
*                   effect.
*
*               (2) PROBE_RS232_UART_3_REMAP_PARTIAL has precedence over PROBE_RS232_UART_3_REMAP_FULL,
*                   if both are defined to DEF_TRUE.
