J.L29 Posted February 5, 2017 Report Share Posted February 5, 2017 Hello, I am new to this forum and have started experimenting with the MPU-6050 a few weeks ago. I am using it for a Design Technology project in hopes of measuring acceleration in any specific direction. After much research it was concluded this cheap, but useful chip was the go-to piece and so after more searching around on youtube I stumbled upon Jeff Rowberg's code. It took me a lot of time to get the processing teapot screen running but it was so worth it. Anyways now that I accomplished that, I moved on to the main task at hand and found out that by uncommented "OUTPUT_READABLE_REALACCEL" . This gave a significant amount of values and raw data in the serial monitor itself but the problem I have is that I do not understand the values or know how to convert them into acceleration that I can then use to perform other functions. I have only started coding last year and I am currently 16 in Year 11. If anyone could give some input or understandable references on the following values I would appreciate that a lot. Send any character to begin DMP programming and demo: Initializing DMP... Enabling DMP... Enabling interrupt detection (Arduino external interrupt 0)... DMP ready! Waiting for first interrupt... areal -293 49 -1190 areal -153 22 66 areal -50 10 868 areal 4 -14 1370 areal 23 -39 1676 areal 59 -54 1878 areal 86 -68 2013 areal 107 -77 2119 areal 119 -83 2175 areal 112 -89 2187 areal 99 -10 72182 areal 116 -118 2198 areal 144 -120 2222 So here is the following data I have received: Also many thanks to Jeff Rowberg for producing such valuable and useful code. I will make sure to include you in my project credits and when I master Arduino I will definitely try to share and teach this to others. Thank you Quote Link to comment Share on other sites More sharing options...
javo Posted February 7, 2017 Report Share Posted February 7, 2017 This is what you can find purely in the MPU-6050 official documentation (https://www.invensense.com/products/motion-tracking/6-axis/mpu-6050/) The MPU-6050 has a word lenght of 16 bits, and the raw value is a discretization of the ±2 scale (default). 16 bits long it's a sensitivity 16384 LSB/g. That means 1g equals to a raw value of 16384. Note that for different scales the sensitivity is different too. From now on it's just elementary math to convert raw values to g-unit or any other acceleration unit. Quote Link to comment Share on other sites More sharing options...
