二,建立STM32 LwIP開發(fā)工程

1,把an3102.zip解壓到D:works形成工程文件夾:D:worksSTM32F107_ETH_LwIP_V1.0.0 ;

2,進入到目錄D:worksSTM32F107_ETH_LwIP_V1.0.0ProjectEWARMv5,雙擊Project.eww打開工程;

3,在EWARM中的Project->make 編譯通過整個項目。

三,修改STM32 LwIP開發(fā)工程

1,打開Project->Options ,在Category中選擇Debugger的setup驅(qū)動用J-Link/J-Trace,在J-Link/J-Trace
中選擇connection的SWD接口;

2,對STM32F107VC-PKT開發(fā)板加上5V的直流電源,把J-LINK用USB線連接到PC的USB口上,執(zhí)行Project->Download and Debug
下載代碼到板子后,執(zhí)行Debug->Go 。

四,修改STM32 LwIP開發(fā)源碼

1,在D:worksSTM32F107_ETH_LwIP_V1.0.0Projectsrcmain.c 的53行后添加如下代碼:

/* Output a message on Hyperterminal using printf function */
printf("");
printf("*** STM32F107VC-PKT V1.0 Build byyuanxihua@21cn.comon ("__DATE__ " - " __TIME__ ")");
printf("*** STM32F107VC-PKT V1.0 Rebooting ...");

2,在D:worksSTM32F107_ETH_LwIP_V1.0.0Projectsrcstm32f107.c 的包含頭文件中添加:
#include "stdio.h"

在第30行選擇用MII模式:
#define MII_MODE /* MII mode for STM3210C-EVAL Board (MB784) (check jumpers setting) */
//#define RMII_MODE /* RMII mode for STM3210C-EVAL Board (MB784) (check jumpers setting) */

在54行后添加:
USART_InitTypeDef USART_InitStructure;

在125行后添加:

/* Configure the com port */
/* 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;

STM_EVAL_COMInit(COM1, &USART_InitStructure);
}

/**
* @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(USART2, (uint8_t) ch);

/* Loop until the end of transmission */
while(USART_GetFlagStatus(USART2, USART_FLAG_TXE) == RESET)
{
}

return ch;
}
/**
* @brief Get a key from the HyperTerminal
* @param None
* @retval : The Key Pressed
*/
int fgetc(FILE *f)
{
/* Waiting for user input */
while ( USART_GetFlagStatus(USART2, USART_FLAG_RXNE) == RESET);
return (uint8_t)USART2->DR;

在341-344行修改為:
/* ADC Channel10 config --------------------------------------------------------*/
/* Relative to STM32F107VC-PKT Board */
/* Configure PC.00 (ADC Channel10) as analog input -------------------------*/
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;

在375-376行修改為:
/* ADC1 regular channel10 configuration */
ADC_RegularChannelConfig(ADC1, ADC_Channel_10, 1, ADC_SampleTime_13Cycles5);

3,在D:worksSTM32F107_ETH_LwIP_V1.0.0Projectsrcetconf.c 中的119-121行和316-318行把
IP地址都修改如下:
IP4_ADDR(&ipaddr, 192, 168, 1, 8);
IP4_ADDR(&netmask, 255, 255, 255, 0);
IP4_ADDR(&gw, 192, 168, 1, 1);

4,在D:worksSTM32F107_ETH_LwIP_V1.0.0Utilitieslwip-1.3.1portlwipopts.h中把
#define LWIP_DHCP 1
修改成:
#define LWIP_DHCP 0

5,在D:worksSTM32F107_ETH_LwIP_V1.0.0UtilitiesSTM32_EVALSTM3210C_EVALstm3210c_eval.h中把
#define LED1_GPIO_PIN GPIO_Pin_7
修改成:
#define LED1_GPIO_PIN GPIO_Pin_13

#define LED2_GPIO_PIN GPIO_Pin_13
修改成:
#define LED2_GPIO_PIN GPIO_Pin_14

#define LED3_GPIO_PIN GPIO_Pin_3
修改成:
#define LED3_GPIO_PIN GPIO_Pin_15


#define COMn 1
修改成
#define COMn 2


6,同樣執(zhí)行Project->Download and Debug 下載代碼到板子后,執(zhí)行Debug->Go 可以全速仿真運行。

五,演示STM32 LwIP開發(fā)工程

1,用交叉網(wǎng)線連接STM32F107VC-PKT到PC的網(wǎng)口,用交叉串口線連接RS232到PC的串口中,再對板子用5V上電
復(fù)位啟動工作;
2,可以在串口終端上用115200 8N1的格式看到:
*** STM32F107VC-PKT V1.0 Build byyuanxihua@21cn.comon (Jan 12 2010 - 12:43:08)
*** STM32F107VC-PKT V1.0 Rebooting ...
3,在PC的IE瀏覽器中輸入:http://192.168.1.8/回車刷新可以訪問到板子,看到Home page主頁:
STM32F107 Webserver Demo
Based on the lwIP TCP/IP stack
4,點擊Led control從Home page切換LED控制,任意勾上或者去掉LED1-3,再按SEND,可以看到板子的LED相應(yīng)的
被控制亮或者滅;
5,點擊ADC status bar從Led control頁面切換到ADC采集,旋轉(zhuǎn)板子上的RV1,可以看到STM32F107 ADC status bar
上綠色的滾動條被ADC的輸入電壓控制增減;
6,在SecureCRT 5.1終端中可以以telnet協(xié)議訪問192.168.1.8,端口就是23,連接上了會顯示:
Hello. What is your name? ,你輸入字符串YUANXIHUA,馬上會回復(fù)Hello YUANXIHUA
