BWS2000倾角传感器c++测试代码
发布时间：2023年12月20日
使用瑞芬的倾角传感器配置的时候，数据手册一下就配置好了，但是BWS2000倾角传感器总是出错，这里进行一下记录出现的问题与解决方式。
1.初步测试
在配置BWS2000倾角传感器读取帧数据的时候，总是出现一个问题，就是进行输出的时候，得到的数据与实际设置的频率并不是不一致的。
其中，command_R1是对于输出频率的设置，command_R2是对于波特率的设置，command_R3保存设置命令。
问题一：注意当COM口大于10的时候，需要在前面添加\\\\.\\，否则会出现连接不上的情况，具体原因见博客：https://www.cnblogs.com/pandamohist/p/13681042.html
问题二：读出来的数据是16进制的，因此需要进行自己转换，
转换过程代码如下所示（这个代码不是最优方式，比较麻烦，懒得再思考了）：
if (sizeof(response_R) >= 13 && response_R[0] == 0x77 && response_R[1] == 0x10)//&& response[3] == 0x84)
{
//x轴
int hexValues[] = { response_R[5] & 0xFF, response_R[6] & 0xFF, response_R[7] & 0xFF };
int numValues = sizeof(hexValues) / sizeof(hexValues[0]);
std::stringstream ss;
ss << std::setfill('0') << std::setw(2) << std::hex << hexValues[0];
//std::cout << "String representation: " << numValues << std::endl;
for (int i = 1; i < numValues; i++) {
ss << "." << std::setw(2) << std::hex << hexValues[i];
}
std::string resultString = ss.str();
std::cout << "X轴 String representation: " << resultString << std::endl;
std::string inputString = resultString;
std::string outputString;
size_t firstDotIndex = inputString.find('.');
size_t secondDotIndex = inputString.find('.', firstDotIndex + 1);
if (firstDotIndex != std::string::npos && secondDotIndex != std::string::npos) {
outputString = inputString.substr(0, secondDotIndex) + inputString.substr(secondDotIndex + 1);
}
else {
outputString = inputString;
}
double resultDouble = std::stod(outputString);
if (response_R[4] == 0x00)
{
Sensor_Angle_RX0 = resultDouble;
}
else
{
Sensor_Angle_RX0 = -resultDouble;
}

int numValues1 = sizeof(hexValues1) / sizeof(hexValues1[0]);
// Convert hexadecimal values to a string "01.0102"
std::stringstream ss1;
ss1 << std::setfill('0') << std::setw(2) << std::hex << hexValues1[0];
std::cout << "String representation: " << numValues << std::endl;
for (int i = 1; i < numValues1; i++) {

}
else {
outputString1 = inputString1;
}
double resultDouble1 = std::stod(outputString1);

Sensor_Angle_RY0 = resultDouble1;
}

在上面的代码之中，我是使用的自动输出的方式，配置的25Hz进行输出，但是出现的问题就是当把下面的代码进行打开之后：
if (sizeof(response_R) >= 13 && response_R[0] == 0x77 && response_R[1] == 0x10)//&& response[3] == 0x84)
{
//x轴
int hexValues[] = { response_R[5] & 0xFF, response_R[6] & 0xFF, response_R[7] & 0xFF };
int numValues = sizeof(hexValues) / sizeof(hexValues[0]);
// Convert hexadecimal values to a string "01.0102"
std::stringstream ss;
ss << std::setfill('0') << std::setw(2) << std::hex << hexValues[0];
//std::cout << "String representation: " << numValues << std::endl;
for (int i = 1; i < numValues; i++) {
ss << "." << std::setw(2) << std::hex << hexValues[i];
}
std::string resultString = ss.str();
//std::cout << "X轴 String representation: " << resultString << std::endl;
std::string inputString = resultString;
std::string outputString;
size_t firstDotIndex = inputString.find('.');
size_t secondDotIndex = inputString.find('.', firstDotIndex + 1);
if (firstDotIndex != std::string::npos && secondDotIndex != std::string::npos) {
outputString = inputString.substr(0, secondDotIndex) + inputString.substr(secondDotIndex + 1);
}
else {
outputString = inputString;
}
double resultDouble = std::stod(outputString);
if (response_R[4] == 0x00)
{
Sensor_Angle_RX0 = resultDouble;
}
else
{
Sensor_Angle_RX0 = -resultDouble;
}
std::cout << "x轴角度" << std::fixed << std::setprecision(4) << resultDouble << std::endl;
//Y轴
int hexValues1[] = { response_R[9] & 0xFF, response_R[10] & 0xFF, response_R[11] & 0xFF };
int numValues1 = sizeof(hexValues1) / sizeof(hexValues1[0]);
std::stringstream ss1;
ss1 << std::setfill('0') << std::setw(2) << std::hex << hexValues1[0];
//std::cout << "String representation: " << numValues << std::endl;
for (int i = 1; i < numValues1; i++) {
ss1 << "." << std::setw(2) << std::hex << hexValues1[i];
}
std::string resultString1 = ss1.str();
std::string inputString1 = resultString1;
std::string outputString1;
size_t firstDotIndex1 = inputString1.find('.');
size_t secondDotIndex1 = inputString1.find('.', firstDotIndex1 + 1);
if (firstDotIndex1 != std::string::npos && secondDotIndex1 != std::string::npos) {
outputString1 = inputString1.substr(0, secondDotIndex1) + inputString1.substr(secondDotIndex1 + 1);
}
else {
outputString1 = inputString1;
}
// Convert the string "01.0102" to double 01.0102
double resultDouble1 = std::stod(outputString1);
if (response_R[8] == 0x00)
{
Sensor_Angle_RY0 = resultDouble1;
}
else
{
Sensor_Angle_RY0 = -resultDouble1;
}
std::cout << "y轴: " << std::fixed << std::setprecision(4) << resultDouble1 << std::endl;
}发现明显输出的频率是和25Hz是不一致的。
然后直接将相应的报文进行打印，调用
for (int i = 0; i < sizeof(response_R); i++) {
printf("%02X ", response_R[i]);
}输出如下结果：
真正想用的的数据是0x77 0x10 0x00数据之后的，也就是尽量是要求每一帧的数据都是这个情况，由于设置了自动输出的频率为25Hz，所以你读取相应的response是不知道在哪一个时刻开始的，需要进行相应的频率进行设置。
2.应答测试
在每个帧信号之后，输出一个应答信号，检测是否输出正确？

当设置波特率为9600，应答模式的情况下，可以见到输出完完全全正确：
但是我需要高频率的输出，见到技术手册里面存在这样一句话，
给定的软件是可以正常运行的。
3.解决高频率输出
当我把频率直接设置成115200的时候，发现还是存在错误，应答信号直接出错了。
我想了很久，然后技术手册之中有一句话是这样说的，
每次变更通信波特率成功之后，会以原来的波特率发送应答信号，然后立即改变通信波特率。
也就是说初始的时候，波特率还是应该设置为9600，发送command_R2完毕之后，才会发生改变。因此，下面这个代码值是不能够发生变化的
只需要将command_R2的值进行变化就是可以的。
运行1348次数据仍然是正确的。
4.界面化设计
此处使用的应答模式
因为代码之中使用自动输出模式，会出现检测代码的问题，前面已经提到过。
后面的思路是在界面之中设定一个定时器，以50Hz的方式进行写读，不会出现读出来的帧数据出错的问题，规避了自动输出的局限性。之后使用线程对于这个定时器进行实时调用就可以了。
