MPU-6050 | MPU-6050 Accelerometer and Gyroscope code | Learning library

I'm trying to send data from my Wemos to Node-red via MQTT. I created a nested object I want to send to MQTT. From the serial of Arduino IDE the output is this (and that's what I want):

[{"AcX":-1,"AcY":-1,"AcZ":-1},{"AcX":-1,"AcY":-1,"AcZ":-1},{"AcX":-1,"AcY":-1,"AcZ":-1},{"AcX":-1,"AcY":-1,"AcZ":-1},{"AcX":-1,"AcY":-1,"AcZ":-1}]

It seems all correct but the debug node show nothing. what am I missing?

Here's the code:

The MPU-6050 is a popular module that contains a temperature sensor, accelerometer, and gyroscope. A user may read the sensor information over I2C or SPI. Two documents are publicly available for reading data out of the IC registers. These are:

1. The MPU-6000 and MPU-6050 Register Map and Descriptions Document

2. The MPU-6000 and MPU-6050 Product Specification

Reading individual registers of the IMU over I2C skews samples across time because of bus communication latency. Consequently, a sequential read of the X, Y, and Z axis registers of a sensor are not synchronized. To address this, the device provides a 1024-byte internal FIFO queue. Data configured to be pushed to the queue are pushed together at the sample rate. Hence reading the FIFO yields synchronized data.

See (2), section 7.17:

The MPU-60X0 contains a 1024-byte FIFO register that is accessible via the Serial Interface. The FIFO configuration register determines which data is written into the FIFO. Possible choices include gyro data, accelerometer data, temperature readings, auxiliary sensor readings, and FSYNC input. A FIFO counter keeps track of how many bytes of valid data are contained in the FIFO. The FIFO register supports burst reads. The interrupt function may be used to determine when new data is available

The datasheets specify that in order to read from the FIFO, you must perform the following:

1. Enable the FIFO (bit 6, register 0x6A, Document (1), Section 4.29)
2. Configure the FIFO with what sensor information to push (register 0x23, Document (1), Section 4.7). I enable XG_FIFO_EN, YG_FIFO_EN, ZG_FIFO_EN, and ACCEL_FIFO_EN by setting bits 6, 5, 4, and 3 respectively.

If you have performed these steps, then it claims (Document (1), Section 4.33) that:

Data is written to the FIFO in order of register number (from lowest to highest). If all the FIFO enable flags (see below) are enabled and all External Sensor Data registers (Registers 73 to 96) are associated with a Slave device, the contents of registers 59 through 96 will be written in order at the Sample Rate. The contents of the sensor data registers (Registers 59 to 96) are written into the FIFO buffer when their corresponding FIFO enable flags are set to 1 in FIFO_EN (Register 35).

However, I find that this does not hold true. Given the flags I have enabled in the configuration register, I expect the following sequence to come from the FIFO:

I'm trying to use a MPU-6050 (GY-521) sensor with my Raspberry Pi 3 and Windows 10 IoT. I'm following this example on Hackster, but the following line

This might sound like a very silly question, so I apologize if this is something very simple but I just cannot get my head around it. I am trying to understand what the data provides in terms of real time information, for example, the MPU-6050:

Gyroscope - is a 16 bit data register with a range from (0 <-> 65535) There is a selection of ranges (±250, ±500, ±1000, and ±2000°/sec)

If the range is set to ±250°/sec, is the reading 360/65535 = 0.0054 resolution?

What does °/sec mean, if the sensor does not move and reads zero and then turned quickly does it mean it will be reading the angle at the set range? For example, if the range was set to ±2000°/sec and it was moved 200° would the read move from 0 to (2/65535 *200) and keep sending this value once the sensor stopped moving?

Accelerometer - is a 16 bit data register with a range from (0 <-> 65535) There is a selection of ranges (±2g, ±4g, ±8g and ±16g)

If the sensor is not moving, completely flat the reading will be 0? If the sensor is shocked at 2g will the max reading be 65535 (if set of 2g, with a resolution of 2/65535) If the sensor is shocked at 16g will the max reading be 65535 (if set of 16g, with a resolution of 16/65535))

I'm using an ESP32 to try to read from an IMU, the MPU-6050. I'm using the code that is available on the Arduino web site with a slight variation; I'm checking the error code on endTransmission and am printing it (I started to do this because I was getting all zero values back from my calls to read the MPU registers). On the very first call to initialize the MPU I receive a success error code. But for ever call after that I receive error code 7. What's odd is when I trace through the Wire library I find that there is no error code 7 defined. The function in question only has 4 possible return values and 7 isn't one of them.

Here is the entirity of the code.

I am building a drone and using an Arduino Uno to mostly control it. However, when I tilt the drone to test it, for example on the X axis, the program says it's been tilted on both the X and Z axis. I am using an MPU6050 gyroscope. Here is the code I am using:

I am using Visual Studio 2017 Communitiy version/ .NET Framework 4.6.1/ WPF. Btw. I use MVVM.

My aim is to display all available serialports in a Combobox. I already implemented this but now I want to make the Combobox automatically update when the Dropdowmenu is opened or a new device is connected. Therefore I would need some property to make Binding to my ViewModel.

On MSDN I found Combobox.DroppedDown-Property which sounds good for me, but I can't use it, DroppedDown is not found...(is System.Windows.Forms the right Reference?).

Do you find my mistake or do you maybe have a better solution?

Thanks!

What is the problem and why do we need to do this?

I recently purchased an MPU6050 breakout board. I tried it with my Arduino Uno, and with my Raspberry Pi 3.

It gives this weird output with Raspberry (without any motion / in stable condition)!

I'm working on a project using InvenSense's Motion Driver API to read values from the MPU-6050. As a start I'm trying to get the temperature.

Reading the register documentation there is the following sentence.

The temperature in degrees C for a given register value may be computed as: Temperature in degrees C = (TEMP_OUT Register Value as a signed quantity)/340 + 36.53

In the source code of this API there is the following function
