Works well! :)

Ah I was uploading to RAM. Uploading to flash works :) (I didn't upload to flash because I had to reset the Pixl when the memory issues came up during upload)
And yeah, modules uploaded as functions is checked.
The module seems to be working, and is quite performant :) Thanks again for the help!

Strangely, trying to upload the code again after the memory problem works. I guess I'll work with this for now :)

I might have spoken too soon; closing and then reopening the Espruino editor gives me a memory error again:

setting both editor and module to closure simple optimizations works!

IntStatus: 3I guess it just barely gets it.
However, I'm planning to use this to stream accelerometer data over BLE so I'm afraid even if the example works, adding more of my own code might take me over the memory limit :(
I'll see what I can do in the meantime :) Thanks!

closure with simple optimizations gives

Here's the code I'm using btw (the same as in the docs, just the I2C options and trigger changed)
I2C1.setup({scl:A5, sda:A4}); const MPU = require("MPU6050").connect(I2C1); // 2nd parameter is the fifoRate. The DMP output frequency = 200Hz / (1 + fifoRate) const DMP = require("https://raw.githubusercontent.com/espruino/EspruinoDocs/master/devices/MPU6050_DMP.js").create(MPU, 3); function pidLoop(args) { var data = DMP.getData(); if(data !== undefined) console.log(DMP.getYawPitchRoll(data)); } setWatch(pidLoop, D13, { repeat:true, edge:'rising' });
Just an update: it works! :)
My order for the voltage regulators from digikey just came and although I knew that they were small, I didn't expect it to be really small when not soldered to anything.
It wasn't my best soldering job as my hands are too shaky with the tight tolerances around the components, but even though I bodged it the module works again :)
