鉴于flymcu下载时有点慢，flash_loader.exe容易卡死的原因，所以决定自己写个串口编程和控制台程序。然后写成bat文件，再整合到Visual studio的外部工具里，实现一键下载。
STM32_ISP的协议文档可以在st的官网上找到。
先说下控制台的大致思路：
程序的目标：把*.bin文件通过指定串口发送到stm32,stm32把收到的*.bin文件数据存到指定的flash地址。
控制台这边要给的指令是：例如：COM4 256000 0X08000000 M:codedebugtext.bin
1.电脑的串口编号: COM4
2.要使用的串口波特率: 256000
3.编程地址: 0X08000000
4.*.bin文件路径: M:codedebugtext.bin
所有的指令可以通过int main(int argc, char** argv)，的**argv指针获得。
例如：把上面的指令通过CMD输入后
程序：
int main(int argc, char** argv)
{
for (int i = 0; i < argc; i++)
{
printf("argv[%d]:%sn", i, argv
);
}
}
运行结果：
argv[0]:M:stm32_isp_programerstm32_isp_programmerDebugstm32_isp_programmer.exe
argv[1]:COM6
argv[2]:256000
argv[3]:0X08000000
argv[4]:M:codedebugtext.bin
但是获得只是文本类型（char *）。
windows 要打开串口的话用需要用WCHAR* 类型。
所以要做一定的类型转换。
字符串转WCHAR:
#include
wchar_t wstr[20];
swprintf(wstr, 20, L"%S", str);
LPCWSTR wstr_p= wstr;
字符串转10进制
字符串转16进制
#include
long baudrate = strtol(setBuadrate_p, &endptr, 10);
long writeAddress = strtol(writeAddress_p, &endptr, 16);
然后是打开串口：
SerialPort.hSerial = CreateFile(filename, //lpFileName
GENERIC_READ | GENERIC_WRITE,//dwDesiredAccess
0, //dwShareMode
NULL,//lpSecurityAttributes
OPEN_EXISTING,//dwCreationDisposition
FILE_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);
}
串口读写：
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:%dn", GetLastError(), lengthwrote);
}
printf("Error:%d Serial write fail, exiting lengthwrote:%dn", 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, exitingn");
exit(1);
}
return(bytesread);
}
如果有加了RTS#控制的话，还可以用RTS来控制单片机复位：
void hardwareReset()
{
UINT8 restTime = 5;
while (restTime--)
{
if (!EscapeCommFunction(SerialPort.hSerial, SETRTS)) {
printf("nEscapeCommFunction error in serial_config, SETRTSn");
fflush(stdout);
exit(1);
}
Sleep(100);
if (!EscapeCommFunction(SerialPort.hSerial, CLRRTS)) {
printf("nEscapeCommFunction error in serial_config, SETRTSn");
fflush(stdout);
exit(1);
}
Sleep(100);
printf("%dn", restTime);
}
}
后面是STM32 ISP协议部分：
主要用到这几个：
void autoBaudrateStart(void);//自动识别波特率
void clear_writeprotect(void);//清除写保护
void get_version(void);//获取bootloader版本号，不同版本支持的指令不一样
void get_id(void);//获取芯片ID
void globalerase_flash(void);//全片清除flash
void program_memory(void);//flash编程
然后是通信格式：
基本是：
1字节命令+1字节命令反码
N字节内容+1字节所有内容字节的^（异或运算）
通信流程：发送指令，等待ACK或者NACK,发送内容，等待ACK或者NACK
主程序：

鉴于flymcu下载时有点慢，flash_loader.exe容易卡死的原因，所以决定自己写个串口编程和控制台程序。然后写成bat文件，再整合到Visual studio的外部工具里，实现一键下载。
STM32_ISP的协议文档可以在st的官网上找到。
先说下控制台的大致思路：
程序的目标：把*.bin文件通过指定串口发送到stm32,stm32把收到的*.bin文件数据存到指定的flash地址。
控制台这边要给的指令是：例如：COM4 256000 0X08000000 M:codedebugtext.bin
1.电脑的串口编号: COM4
2.要使用的串口波特率: 256000
3.编程地址: 0X08000000
4.*.bin文件路径: M:codedebugtext.bin
所有的指令可以通过int main(int argc, char** argv)，的**argv指针获得。
例如：把上面的指令通过CMD输入后
程序：
int main(int argc, char** argv)
{
for (int i = 0; i < argc; i++)
{
printf("argv[%d]:%sn", i, argv
);
}
}
运行结果：
argv[0]:M:stm32_isp_programerstm32_isp_programmerDebugstm32_isp_programmer.exe
argv[1]:COM6
argv[2]:256000
argv[3]:0X08000000
argv[4]:M:codedebugtext.bin
但是获得只是文本类型（char *）。
windows 要打开串口的话用需要用WCHAR* 类型。
所以要做一定的类型转换。
字符串转WCHAR:
#include
wchar_t wstr[20];
swprintf(wstr, 20, L"%S", str);
LPCWSTR wstr_p= wstr;
字符串转10进制
字符串转16进制
#include
long baudrate = strtol(setBuadrate_p, &endptr, 10);
long writeAddress = strtol(writeAddress_p, &endptr, 16);
然后是打开串口：
SerialPort.hSerial = CreateFile(filename, //lpFileName
GENERIC_READ | GENERIC_WRITE,//dwDesiredAccess
0, //dwShareMode
NULL,//lpSecurityAttributes
OPEN_EXISTING,//dwCreationDisposition
FILE_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);
}
串口读写：
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:%dn", GetLastError(), lengthwrote);
}
printf("Error:%d Serial write fail, exiting lengthwrote:%dn", 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, exitingn");
exit(1);
}
return(bytesread);
}
如果有加了RTS#控制的话，还可以用RTS来控制单片机复位：
void hardwareReset()
{
UINT8 restTime = 5;
while (restTime--)
{
if (!EscapeCommFunction(SerialPort.hSerial, SETRTS)) {
printf("nEscapeCommFunction error in serial_config, SETRTSn");
fflush(stdout);
exit(1);
}
Sleep(100);
if (!EscapeCommFunction(SerialPort.hSerial, CLRRTS)) {
printf("nEscapeCommFunction error in serial_config, SETRTSn");
fflush(stdout);
exit(1);
}
Sleep(100);
printf("%dn", restTime);
}
}
后面是STM32 ISP协议部分：
主要用到这几个：
void autoBaudrateStart(void);//自动识别波特率
void clear_writeprotect(void);//清除写保护
void get_version(void);//获取bootloader版本号，不同版本支持的指令不一样
void get_id(void);//获取芯片ID
void globalerase_flash(void);//全片清除flash
void program_memory(void);//flash编程
然后是通信格式：
基本是：
1字节命令+1字节命令反码
N字节内容+1字节所有内容字节的^（异或运算）
通信流程：发送指令，等待ACK或者NACK,发送内容，等待ACK或者NACK
主程序：
