关于MPU6050与Mega配合使用的问题
大家好,初次发帖,不妥之处请见谅。最近在做自己的平衡车,在论坛里面看了不少关于6050的帖子,学到了很多。
但坛子里面大多数使用uno来配合6050,我是用mega,它提供了专门的scl与sda接口,所以我就试着直接把它们与6050连接起来,结果连接时成功了,但不知道为什么只能上传有限组的数据。
如图:
请问这可能是什么原因造成的?谢谢!
代码如下(直接使用了某个帖子中的代码):
// Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation
// is used in I2Cdev.h
#include "Wire.h"
// I2Cdev and MPU6050 must be installed as libraries, or else the .cpp/.h files
// for both classes must be in the include path of your project
#include "I2Cdev.h"
#include "MPU6050.h"
// class default I2C address is 0x68
// specific I2C addresses may be passed as a parameter here
// AD0 low = 0x68 (default for InvenSense evaluation board)
// AD0 high = 0x69
MPU6050 accelgyro;
int16_t ax, ay, az;
int16_t gx, gy, gz;
#define LED_PIN 13
bool blinkState = false;
void setup() {
// join I2C bus (I2Cdev library doesn't do this automatically)
Wire.begin();
// initialize serial communication
// (38400 chosen because it works as well at 8MHz as it does at 16MHz, but
// it's really up to you depending on your project)
Serial.begin(230400);
// initialize device
Serial.println("Initializing I2C devices...");
accelgyro.initialize();
// verify connection
Serial.println("Testing device connections...");
Serial.println(accelgyro.testConnection() ? "MPU6050 connection successful" : "MPU6050 connection failed");
// configure Arduino LED for
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// read raw accel/gyro measurements from device
accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);
// these methods (and a few others) are also available
//accelgyro.getAcceleration(&ax, &ay, &az);
//accelgyro.getRotation(&gx, &gy, &gz);
// display tab-separated accel/gyro x/y/z values
Serial.print("a/g:\t");
Serial.print(ax);
Serial.print("\t");
Serial.print(ay);
Serial.print("\t");
Serial.print(az);
Serial.print("\t");
Serial.print(gx);
Serial.print("\t");
Serial.print(gy);
Serial.print("\t");
Serial.println(gz);
// blink LED to indicate activity
blinkState = !blinkState;
digitalWrite(LED_PIN, blinkState);
}
刚用6050还不是很理解 有限组的数据是啥意思?
跑着跑着停了? zoologist 发表于 2015-11-24 22:18 static/image/common/back.gif

是的,:dizzy: 我注意到你设置串口比较特别
Serial.begin(230400);
你有没有试试115200 这样标准的? zoologist 发表于 2015-11-28 20:15 static/image/common/back.gif

Serial.begin(230400);
没有欸,下次去实验室试试,谢谢了 zoologist 发表于 2015-11-28 20:15 static/image/common/back.gif

我试过了,各个波特率,好像没什么区别:( c_bowie 发表于 2015-12-8 10:41 static/image/common/back.gif

那你就试试直接输出随机数看看会不会停吧
其他的都不要变 本帖最后由 c_bowie 于 2015-12-15 10:10 编辑

感谢您耐心回复,我做了测试,在loop循环里面只有把accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);给注释掉才能不停地输出,否则只会进行有限组的loop循环。 c_bowie 发表于 2015-12-15 10:09 static/image/common/back.gif

内存溢出?库函数有问题? zoologist 发表于 2015-12-15 11:16 static/image/common/back.gif
内存溢出?库函数有问题?
是啊,感觉可能是由于库文件与6050不匹配 楼主,你的传感器和mega的那些引脚相连接的啊。我也在做,求教啊!
