Hey JS lovers, I ordered the BNO055, a 9-DoF chip that calculates orientation on board, and gives output as Euler or quaternion angles. Time for some fun!

This will be my first time writing a module for a chip. If any pointers or tips on how to do it, I would be glad to hear. I think I'm going to look at the existing Arduino code on the Adafruit site, and port to JS.

But first, I need to figure out how to connect BNO055 to Espruino WiFi. And is connecting it enough? Will Espruino WiFi provide all needed power for the BNO055 just from being connected to the Espruino WiFi? I'm a complete newb, so just throwing questions out there.

On my way to the store to get my first soldering iron and bread board(s).

Oh crap, but a breadboard won't enforce the pins being snug inside the holes. The pins are loose.

Are there pins that can tighten to fit snug in the holes?

Maybe I just need to buy a few of these and just solder them to have room for mistakes.

Thanks for the links @ClearMemory041063 :}

did you try typing save() into the left hand side of the IDE?

Ah, I missed the save() function. Thanks!

Alright, thanks. Looks like I gotta run to the store and get a breadboard because when I jiggle the chip, it seems to cause the Espruino to power cycle.

Do I need to have a separate battery aside from the USB connection? If so, any type of batteries to recommend, with link or photo?

(I'm a total complete newb, never hooked a chip up to a battery before.)

I tried uploading code to Espruino WiFi, then disconnected it and connected it to a USB battery, but then the code doesn't work (just LED lights blinking).

Seems like disconnecting the reconnecting to the battery erases the code. How do I get it to stay on there?

@Gordon Thanks, I didn't get those exact ones, I got wires like the ones in http://forum.espruino.com/conversations/305040/

Would those wires work the same?

I put the pins through the holes like in the photo, but the chip is somewhat loose. It doesn't seem like the pins and wires are enough. Maybe I do need a breadboard so the connection is solid?

I got an MPU6050, and I connected the wires based on what the doc for the module says. When I run my code, it seems like Espruino freezes (the command line in the IDE becomes unresponsive).

Maybe I didn't connect the wires properly? I am using wires but no solder (see photo, the module is on bottom, the pins are fastened with the wires but not soldered). Maybe it really needs solder?

Or if that should be good enough for prototyping, maybe there's something wrong in code or with the module? Here's my code:

I2C1.setup({scl:B6,sda:B7});

var MPU6050 = require("MPU6050");
console.log(MPU6050);

var mpu = MPU6050.connect(I2C1);

setInterval(() => {
  console.log(
    '\nAcceleration:', mpu.getAcceleration(), // returns an [x,y,z] array with raw accl. data
    '\nGravity:', mpu.getGravity(),  // returns acceleration array in G's
    '\nRotation:', mpu.getRotation(), // returns an [x,y,z] array with raw gyro data
    '\nDegress per second:', mpu.getDegreesPerSecond() // returns gyro array in degrees/s
  );
}, 1000);

What are some steps I can take to diagnose the problem?

Webpack's shiny new feature is tree shaking (when writing with ES6 Module format rather than CommonJS, or using a webpack loader that takes current CommonJS and outputs ES6). We can set Babel as a transpiler, and make a babel-preset-espruino which compiles only the language features that Espruino doesn't have natively yet. After that, running the "webpack" command can compile a minified bundle from an entry point (unused code not included, and duplicate code consolidated), then one more step with the espruino CLI will upload the file.

I'm sure that can then be easily automated in the IDE.

Is it the female to female wires, like these ones?

Thanks! Looks like the MPU6050 is going to be easier to work with to just get up and running with the existing module. You're right, making a module for the Tessel accelerometer based on Adafruit's code does seem fairly easy, but I'm definitely going to skip on that if the MPU6050 simply works.

Does the espruino come with a bread board? Or is it just the chip? I got this MPU6050: http://www.ebay.com/itm/171036006952

I just ordered Espruino WiFi, and the MPU6050 module. What else might I need to order in order to get it all working and connected? Or is just ordering those two things enough?

I suppose it doesn't matter much since I bought both the Tessel+Accelerometer and Espruino+MPU6050 module, so I can experiment. :D

My guess is that to make Tessel's work on Espruino I would have to write an Espruino module for it.

Hello, I ordered a Tessel2 + Accelerometer, and I'd also like to order an Espruino. I am wondering if I can hook the Tessel Accelerometer to an Espruino, or if I should buy another accelerometer?

I'm sort of new to all this, I only have prior experience with an Arduino but not connecting things to it.

I suppose it is simply a matter of sending the correct electrical signals into the Tessel Accelerometer, but I'm not sure how easy/hard that will be.
