鑒于flymcu下載時有點慢，flash_loader.exe容易卡死的原因，所以決定自己寫個串口編程和控制臺程序。然后寫成bat文件，再整合到Visual studio的外部工具里，實現(xiàn)一鍵下載。

STM32_ISP的協(xié)議文檔可以在st的官網(wǎng)上找到。

先說下控制臺的大致思路：

程序的目標：把*.bin文件通過指定串口發(fā)送到stm32,stm32把收到的*.bin文件數(shù)據(jù)存到指定的flash地址。

控制臺這邊要給的指令是：例如：COM4 256000 0X08000000 M:\code\debug\text.bin

1.電腦的串口編號: COM4

2.要使用的串口波特率: 256000

3.編程地址: 0X08000000

4.*.bin文件路徑: M:\code\debug\text.bin

所有的指令可以通過int main(int argc, char** argv)，的**argv指針獲得。

例如：把上面的指令通過CMD輸入后

程序：
?

int main(int argc, char** argv) {for (int i = 0; i < argc; i++){printf("argv[%d]:%s\n", i, argv[i]);}}

運行結(jié)果：

argv[0]:M:\stm32_isp_programer\stm32_isp_programmer\Debug\stm32_isp_programmer.exe
argv[1]:COM6
argv[2]:256000
argv[3]:0X08000000
argv[4]:M:\code\debug\text.bin

但是獲得只是文本類型（char *）。

windows 要打開串口的話用需要用WCHAR* 類型。

所以要做一定的類型轉(zhuǎn)換。

字符串轉(zhuǎn)WCHAR:

#include <Windows.h> wchar_t wstr[20]; swprintf(wstr, 20, L"%S", str); LPCWSTR wstr_p= wstr;

字符串轉(zhuǎn)10進制

字符串轉(zhuǎn)16進制

#include <stdlib.h> long baudrate = strtol(setBuadrate_p, &endptr, 10); long writeAddress = strtol(writeAddress_p, &endptr, 16);

然后是打開串口：

SerialPort.hSerial = CreateFile(filename, //lpFileNameGENERIC_READ | GENERIC_WRITE,//dwDesiredAccess0, //dwShareModeNULL,//lpSecurityAttributesOPEN_EXISTING,//dwCreationDispositionFILE_ATTRIBUTE_NORMAL,NULL);//hTemplateFile

串口配制：

SerialPort.NewDCBParams.BaudRate = baudrate; SerialPort.NewDCBParams.ByteSize = 8; SerialPort.NewDCBParams.StopBits = ONESTOPBIT; SerialPort.NewDCBParams.Parity = EVENPARITY; if (!SetCommState(SerialPort.hSerial, &SerialPort.NewDCBParams)) {printf("\nSetCommState error!\n");fflush(stdout);return(1); } COMMTIMEOUTS timeouts = { 0 }; timeouts.ReadIntervalTimeout = 1000; timeouts.ReadTotalTimeoutConstant = 1000; timeouts.ReadTotalTimeoutMultiplier = 10; timeouts.WriteTotalTimeoutConstant = 50; timeouts.WriteTotalTimeoutMultiplier = 10; if (!SetCommTimeouts(SerialPort.hSerial, &timeouts)) {printf("\nSetCommTimeouts error!\n");fflush(stdout);return(1); }

串口讀寫：

DWORD serial_write(unsigned char* buffer, DWORD len) {DWORD lengthwrote;if (!WriteFile(SerialPort.hSerial, buffer, len, &lengthwrote, NULL)) {if (GetLastError() == ERROR_IO_PENDING){printf("Error:%d Serial write fail, exiting lengthwrote:%d\n", GetLastError(), lengthwrote);}printf("Error:%d Serial write fail, exiting lengthwrote:%d\n", GetLastError(), lengthwrote);exit(1);}return(lengthwrote); } DWORD serial_read(unsigned char* buffer, size_t len) //windows version {DWORD bytesread;if (!ReadFile(SerialPort.hSerial, buffer, len, &bytesread, NULL)) {printf("Error: Serial read fail, exiting\n");exit(1);}return(bytesread); }

如果有加了RTS#控制的話，還可以用RTS來控制單片機復(fù)位：

void hardwareReset() {UINT8 restTime = 5;while (restTime--){if (!EscapeCommFunction(SerialPort.hSerial, SETRTS)) {printf("\nEscapeCommFunction error in serial_config, SETRTS\n");fflush(stdout);exit(1);}Sleep(100);if (!EscapeCommFunction(SerialPort.hSerial, CLRRTS)) {printf("\nEscapeCommFunction error in serial_config, SETRTS\n");fflush(stdout);exit(1);}Sleep(100);printf("%d\n", restTime);} }

?

后面是STM32 ISP協(xié)議部分：

主要用到這幾個：

void autoBaudrateStart(void);//自動識別波特率 void clear_writeprotect(void);//清除寫保護 void get_version(void);//獲取bootloader版本號，不同版本支持的指令不一樣 void get_id(void);//獲取芯片ID void globalerase_flash(void);//全片清除flash void program_memory(void);//flash編程

然后是通信格式：

基本是：

1字節(jié)命令+1字節(jié)命令反碼

N字節(jié)內(nèi)容+1字節(jié)所有內(nèi)容字節(jié)的^（異或運算）

通信流程：發(fā)送指令，等待ACK或者NACK,發(fā)送內(nèi)容，等待ACK或者NACK
