  If I make any real progress I will do so.

• MPU6050 Module issue

  in Pico / Wifi / Original Espruino • 12 hours, 33 minutes

  

  I realized the the error Uncaught InternalError: Timeout on I2C Write BUSY was because of bad header pins! I somehow got a batch of headers that didn't have any beveling on them, this caused damage to my solderless breadboard and contrsibuted to a poor connection. I always use high quality solderless breadboards to reduce issues but I never anticipated bad header pins!

  I think how the module initiates the MPU isn't perfect but it does work well enough for my purposes. If I have time , I might go though the module and modify it for myself. I want to see if I can make initialization more consistent and I want to eliminate verbose warning and error messages. My end goal it to interface my "robot" with an app on my phone(written with droidscript) . I like being able to interface directly using the console over BLE (jolt), it is very powerful and is one of the best features of the espruino environment. I don't want to filter all these warning messages from the module. The "puck" addon in Droidscript works flawlessly for interfacing with the espruino console over BLE and I have been using that for a bunch of little things. I like that I can program any BLE Espruino with my phone. I wrote a droidscript app with a dropdown menu of programs that I can upload at-will to espruino and it is very handy!

  When I get home from work I will try to use the soft I2c connection to see if it helps with MPU initialization, thanks for the suggestion! I forgot that I can do that.

  Keep up the good work with Espruino, It is by far my favorite platform for tinkering.

  Thank you for your quick response, I took a look at the module and it didn't occur to me that the default parameters would be an issue.

  I'm still having some issues with this module but I think it is mostly how I'm starting the I2c Communications when Loading this code to RAM.

  It sometimes works and starts up right way but a lot of the time it fails to start. I get this:

  I will play with it more to find the source of the issue. I will play with putting the code in flash and setting up the I2c using onInit().

  I remember getting I2C devices to initialize is tricky and this may be an issue with how I'm doing things

  Thanks again !

  My goal is to use this module with a Jolt.js I just got. I have the Jolt attached to a little robot chassis. The issue with the small robot is that I don't know if it is going a a straight line or not, so I want to incorporate an MPU to track the "yaw" of the chassis as it drives along and eventually correct itself.
  If anyone reading this knows of a better MPU or has suggestions please drop a comment.

  I'm not sure what the issue is with this module(MPU 6050), but it only works when using the web IDE using Minification; specifically "Closure(online) - Simple Optimizations" , It fails when using Esprima (offline) or any other minification.

  I'm currently trying to use this module on a Pico that was just updated to the latest firmware (2v25)
  I have a working mpu6050 and I can get it to function under these very strict circumstances, but it feels like a kludge.

  I'm just wondering why it would only work under such specific circumstances, is there anything that could be done to make the module more reliable?

  This is not a huge concern but I'm wondering if there are some obvious reasons this module would behave this way.

  I2C1.setup({scl:B6, sda:B7, bitrate:100000});
  const MPU = require("MPU6050").connect(I2C1);
  // 2nd parameter is the fifoRate. The DMP output frequency = 200Hz / (1 + fifoRate)
  const DMP = require("MPU6050_DMP").create(MPU, 1);
  
  function pidLoop(args) {
    if (digitalRead(B5)) {
    var data = DMP.getData();
    if(data !== undefined) console.log(DMP.getYawPitchRoll(data));
  }
  }
  

  I get this error :

  Uncaught SyntaxError: Got '!' expected ','
  at line 1 col 2110
  ...yBank=function(a,bundefined!1,dundefined!1){a&=31,d&&(a|=32)...

  I would be happy to contribute to the espruino community!

  thanks for your help! I will play around with this method and write some code to produce the correct strings of bits. I'll do some testing with a sent decoder. If I find that it works well, I can try to write something up, perhaps others will find this useful.

  I would really like to try it on the nRF52, i can verify with an ocsilloscope , if anything it will be a learning experiance.
