Wouldn't the usual way be to just try mounting and evaluate except? EMMC is definitely not a hot-plug device. I have not fitted my WBUS-EMMC as yet but I am interested in this topic because I will start experimenting soon. The WBUS-EMMC documentation states "This WBUS-EMMC replaces an SD-Card. It's...

I've implemented what you require witn a ring buffer. I can't get speeds significantly higher than 8kHz. The write time takes too long and the indexes cross. If you want me to post my code just ask in this thread. use the fastest microsd card you can put your hands on and try to write in binary , p...

...i just don't recognize the L1 component on A3V3 via from pyboard v1 schematic... Looking at https://github.com/micropython/pyboard/blob/master/PYBv10b.pdf and scrolling down to the layout it's a surface mount inductor. The question is the units of its 1K value. nH? Yes i supposed that is an Indu...

Thanks guys, now i'm using a "upgrade switch" to boot on DFU mode, the serial debugging feature is something that i want to do already. I've made a minimum pyboard based schematic on kicad to help someone who want to design over it. i just don't recognize the L1 component on A3V3 via from pyboard v1...

Hy guys! I "finish" my script-side for a custom board using micropython and pyboard to develop and now i want to design my own board (today it's a mess of wires and connectors..) I've experience with microchip environment and atmel also but know nothing about st... my question is very basic: I will ...

Take a look on this document:

it explains the math, but atan2() function will help you.

I think that warning only applies to the WiPy (hint: only the WiPy has pins named like GP4) and should only be included in the WiPy specific documentation. I think that when the machine docs were first written, only the WiPy implemented it. Now that there are several implementations, the docs need ...

The analog inputs on the pyboard are good up to 3.3v. Why do you think that its only good to 1.8v? yes, i read that on http://docs.micropython.org/en/latest/pyboard/library/pyb.ADC.html but yesterday i was making a kicad component for pyb shield and i saw this library as well: It have an warning fo...

Hi guys, i was trying to read an pressure sensor with output of 0.2 to 3.3v months ago, after some annoying hours of head breaking (i have access to an reference pressure sensor to comparison), i give up.. now i open again the documentation and i see that the AD from pyb is up to 1.8v? I need a volt...

Coming back to the display... I've tried to use the latest code... https://github.com/khenderick/micropython-drivers I'm using a stock AdaFruit 64X128 display... https://www.adafruit.com/product/938 When I attempt to use the example, I get. I know the display works (tested it under with Arduino Uno...
