Re: MicroPython on Kite

Awesome! no it won't fit, it's about 26mmx34mm Hmmm, if it is 26mm wide, it might... If it weren't for the SD card sticking out the side, it would fit. That implies I could possibly use it as a down-facing sensor, but not a recording device, unless I could find a flexible uSD extension cable. I sho...

I don't think your board will fit inside though - the inside diameter of the shell is only 29mm.

Re: NanoSeeker (underwater robot)

I'm making a couple changes to my PCB, and ordering a new one. I posted the details on my blog, but basically it comes down to the bluetooth module I chose not being useful in the mode I needed it to work in.

Re: New Pin Compatible STM32 F7

Actually, it may be pin compatible, but only with 100-pin and higher versions of the chip. We use the 64 pin version of the chip, so it doesn't look like this is going to be a simple option.

Re: Module for MPU9150

Yeah, I don't have the two buses connected, so I have to use bypass mode. Fortunately, I found the right sequence of bytes to send to the device initially that puts it in bypass mode (last comment): http://diydrones.com/profiles/blogs/secrets-of-the-mpu9150?id=705844%3ABlogPost%3A1107213&page=2#comm...

Re: Module for MPU9150

Turbinenreiter, So I've got my first NanoSeeker board up and running, and I've tried your code (from github) with my on-board MPU-9150. The device responds, and I can access the accelerometer and the gyro, but the compass doesn't show up. I tried setting the pass-through registers, but the compass d...

Re: NanoSeeker (underwater robot)

As an update, I've put together my first new NanoSeeker board, and it is running MicroPython... http://www.huv.com/nanoSeeker/PCB-01-small.jpg Here's a video of it running a simple LED flasher: https://www.youtube.com/watch?v=6JCUt19zGeE The code is from the wiki: http://micropython.org/doc/tut-leds

Re: Reading a temperature value from a TMP36 sensor

More specifically, the voltage that the sensor outputs is not relative to the input, so Vin is irrelevant.

Re: repl without usb

My brother Dave had a patch at one point that allowed me to run the REPL over one of the UARTs. I don't know what the status is now.

Re: Interupts

Here's my hacked-together pre-stmhal version of quadrature encoders, using just straight interrupt-on-change. Not very useful, except it works and shows how to set up the interrupts and registers for this kind of thing,
