"MPU6050_6Axis_MotionApps_V6_12.h" and "newly added calibration code using PID in MPU6050.cpp" make compilation error.

[kmg3821]

There are quite a lot of mismatches for data type. For instance, in "MPU6050_6Axis_MotionApps_V6_12.h",

I2Cdev::writeBit(devAddr,0x6B, 7, &(val = 1));
--> Last parameter's data type is _uint8_t*

However, in the latest version of "I2Cdev.h",

static bool writeBit(uint8_t devAddr, uint8_t regAddr, uint8_t bitNum, uint8_t data);
--> It must be _uint8_t.

Is there any solution for this problem without changing corresponding data type?

right now, I've removed the code which was making error. Then, works!

I think those should be written with MPU6050.cpp functions.

Having similar problem with Arduino IDE when trying to compile MPU6050_DMP_using_DMP_V6.12

Arduino: 1.8.8 (Windows 10), Board: "Arduino/Genuino Uno"

As long as you have the latest code from the master branch (particularly the /Arduino/MPU6050/* files), this should no longer happen.

Same issue with ESP32 :(

'class MPU6050' has no member named 'PrintActiveOffsets'

What is the date of the changelog on top of your MPU6050.cpp file ?

Mine is this and it works:

Changelog:
//  2019-07-08 - Added Auto Calibration routine

I struggled a lot to make it work in a custom C++ class on a ESP32 but now it is pretty good.

Thanks a lot for your fast reply @intensite !

I moved folders I2Cdev and MPU6050 from Arduino folder into my custom libraries folder. When executing DMP 6.12 example I'm getting typedef unsigned long prog_uint32_t; error for ESP32 board. So what I did was replacing custom lib files with files from ESP32_ESP-IDF/components which seems like they not include all necessary methods. Must I use the ESP32_ESP-IDF folder in a different way?

Got it working now with DMP6 demo instead. Had to do some changes like described here: #367 But instead of adapting I2Cdev.cpp change file MPU6050.cpp instead.

[intensite]

Yes I recall seing this. I probably applied this change early on but just didn't remember.
What do you use for I2CDEV_IMPLEMENTATION? I was never able to use anything else than the standard "Wire.h" with the ESP32. I use it like this

Wire.begin(SDA, SCL, 400000);

[bart]

It uses the default here for I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE which is just a Wire.begin();
