Re: I2C, MSB, LSB, endianness and I'm in over my head

... 1*16 + 1*11 = 443 Obviously, that's not how MSB/LSB works. Also, despite being wrong, 443 would better fit to what's in the datasheet^^ http://www.adafruit.com/datasheets/BST-BMP180-DS000-09.pdf page 15 It also should be noted that bits and bytes should not be mixed up. True! It was a typo in the ...

Re: Driving more than 4 servos

... a friend designed: https://www.logre.eu/wiki/JIXClock https://github.com/fma38/JIXoo I also found other more servo-oriented devices: http://www.adafruit.com/product/815 http://www.hobbytronics.co.uk/servo-controller-12ch-ht Pololu also has a nice device, with more features: http://www.pololu.com/product/1357 ...

Documentation for optional extras

... find any documentation on extra goodies either on the official website, this forum or the Google+ forum. The wireless card supplied is not the Adafruit one mentioned in the Kickstarter updates and I can't find anything about the display board either Somewhat at a loss as to how I can safely ...

Light printer

Playing around with a micropython board and some Adafruit "Neopixel" LEDs to make a light printer. https://pbs.twimg.com/media/BqSBWhPCEAAvXDX.png:large It's not very sophisticated as yet. I tried to key the updates to the accelerometer, but it turned ...

Re: Working WS2812 LED Example

Nice one, works well with Adafruit "Neopixels" as well, they use that same LED.

Module for reading from MPL115A2 pressure sensor

I put together a module for reading from a Freescale MPL115A2 barometric pressure sensor: https://github.com/khoulihan/micropython-mpl115a2 Adafruit sell a breakout for this sensor, and the code owes a lot to their Arduino library: https://www.adafruit.com/products/992 https://github.com/adafruit/Adafruit_MPL115A2

Re: How fast can an output pin be toggled?

I think I see what you are suggesting. I maybe missing something but I don't see what the advantage is setting up the DMA to pump out the data like that. Its not like you've offloaded the cpu so it could do something else while the transfer is happening. Implementing a bitbang function in assembler...

Re: Ideas for the project

The MPU6050 is a cheap good device with I2C support. It'll probably be a good start. Many places sell a breakout board - E.g. Adafruit or one of the Ali-Express Chinese suppliers. I hope to port the I2C lib to python soon... ish... but feel free to get started without me. Original C ...
