三,配置STM32 LCCD工程
在EWARM的左面“Workspace”窗口下面的“Files”的“lccd - Debug”左击鼠标,选择“Project”->“Options”出现“Options for node "lccd"”窗口;
1,在左面“Category:”中选择上“General Options”,在“Target”->“Processor Variant”->“Device”中选择“ST STM32F10xx8”,
在“Library Configuration”->“Library”中选择“FULL”;
2,在左面“Category:”中选择上“C/C++ Complier”,在“Preprocessor”->“Additional include directories:”中填上下面几行:
$PROJ_DIR$\..\..\Include

2,在EWARM菜单中“Project”->“Download and Debug”打开下载调试命令;
3,在EWARM菜单中“Debug”->“Go”打开全速运行命令;
4,其它调试命令请自行尝试;
五,修改STM32 LCCD工程
1,移植USART的PRINTF应用
A,把D:\works\lccd-1.0.0\Include\stm32f10x_conf.h的第46行的注释打开;
B,把D:\works\lccd-1.0.0\Project\Examples\USART\Printf\platform_config.h 复制到D:\works\lccd-1.0.0\Include\目录;
C,把D:\works\lccd-1.0.0\Project\Examples\USART\Printf\main.c 复制到D:\works\lccd-1.0.0\Source;
D,编译调试即可以在 RT1看到115200 8N1的字符“USART Printf Example: retarget the C library printf function to the USART”
2,整理USART的PRINTF应用
A,选择Workspace”窗口下的“DRV”用“Project”->“Add Files”把“D:\works\lccd-1.0.0\Drivers\ rt.c”添加到工程;
D:\works\lccd-1.0.0\Drivers\ rt.c的源码如下:
/* Includes ------------------------------------------------------------------*/
#include "stm32f10x.h"
#include "stdio.h"
#include "platform_config.h"
/** @addtogroup StdPeriph_Examples
* @{
*/
/** @addtogroup USART_Printf
* @{
*/
/* Private typedef -----------------------------------------------------------*/
/* Private define ------------------------------------------------------------*/
/* Private macro -------------------------------------------------------------*/
/* Private variables ---------------------------------------------------------*/
/* Private function prototypes -----------------------------------------------*/
void RT_Configuration(void);
/* Private functions ---------------------------------------------------------*/
/**
* @brief Configures the different GPIO ports.
* @param None
* @retval : None
*/
void RT_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
USART_InitTypeDef USART_InitStructure;
#if defined USE_USART2 && defined USE_STM3210B_EVAL
/* Enable AFIO clock */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);
/* Enable the USART2 Pins Software Remapping */
GPIO_PinRemapConfig(GPIO_Remap_USART2, ENABLE);
#endif
/* Configure USARTx_Tx as alternate function push-pull */
GPIO_InitStructure.GPIO_Pin = GPIO_TxPin;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOx, &GPIO_InitStructure);
/* Configure USARTx_Rx as input floating */
GPIO_InitStructure.GPIO_Pin = GPIO_RxPin;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOx, &GPIO_InitStructure);
/* USARTx configuration ------------------------------------------------------*/
/* USARTx configured as follow:
- BaudRate = 115200 baud
- Word Length = 8 Bits
- One Stop Bit
- No parity
- Hardware flow control disabled (RTS and CTS signals)
- Receive and transmit enabled
*/
USART_InitStructure.USART_BaudRate = 115200;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No ;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
/* Configure the USARTx */
USART_Init(USARTx, &USART_InitStructure);
/* Enable the USARTx */
USART_Cmd(USARTx, ENABLE);
}
/**
* @brief Retargets the C library printf function to the USART.
* @param None
* @retval : None
*/
int fputc(int ch, FILE *f)
{
/* Write a character to the USART */
USART_SendData(USARTx, (uint8_t) ch);
/* Loop until the end of transmission */
while(USART_GetFlagStatus(USARTx, USART_FLAG_TXE) == RESET)
{
}
return ch;
}
/*******************************************************************************
* Function Name : fgetc
* Description : Get a key from the HyperTerminal
* Input : None
* Output : None
* Return : The Key Pressed
*******************************************************************************/
int fgetc(FILE *f)
{
/* Waiting for user input */
while ( USART_GetFlagStatus(USARTx, USART_FLAG_RXNE) == RESET);
return (uint8_t)USARTx->DR;
}
B,修改D:\works\lccd-1.0.0\Source\main.c的int main(void)如下:
int main(void)
{
/* System Clocks Configuration */
RCC_Configuration();
/* Configure the GPIO ports */
RT_Configuration();
/* Output a message on Hyperterminal using printf function */
printf("\n\r\n\r\n\r\n\r");
printf("*** LCCD V1.0 Build by y nxih @21cn.com on ("__DATE__ " - " __TIME__ ")\n\r");
printf("*** LCCD V1.0 Rebooting ...\n\r");
while (1)
{
}
}
并在文件前添加:
extern void RT_Configuration(void);
