Re: X2 destroyed, other PWM pins?

Well, unsoldering is kind of risky. The board itself has several layers and it is easy to damage the actual contact area with the (header) pins that will go through the whole. I consider it damaged because I soldered it well and there is contact between the board and the external device so the solde...

Re: Running 12+ servos with the pyboard?

But is it a bad idea to power the servos directly from the pyboard? Back currents and spikes could damage the pyboard or at least cause a brownout?

Adding Bluetooth directly to the pyboard (instead of external module)?

So we have the WiPy that offers Wifi directly on the board and there is the JYMCU external chip that can be used with the pyboard. But it would be nice to have Bluetooth directly on the pyboard, the JYMCU is quite big so adds a lot of space to add it to your design. Any plans to add Wifi or Bluetoot...

Running 12+ servos with the pyboard?

How many servos can you run with the pyboard? if you supply the servos with a separate power supply then it could be as many as the nbr of PWM channels of the pyboard right? Or the pyboard and servos need a common ground? One option is one of these: https://www.adafruit.com/products/815 What solutio...

Re: Pulse width in microseconds (like pulseIn in Arduino)

Why are you not taking the 8 bursts into account? They come before the input signal on the echo pin to right? So how do you know it is the bursts or the actual measurement if you don't capture the 8 bursts first? It seems your algorithm would always return the same (and erronous) distance since it w...

X2 destroyed, other PWM pins?

Seems like I destroyed the X2 pin when I unsoldered some header pins. Is there another pin that can be used instead for PWM?

Re: Project: run existing Python applications with MicroPython

Why Django and not Flask? Flask seems more suited.

Re: Resetting board will not run main.py

Micro Python v1.3.3 on 2014-10-02; PYBv1.0 with STM32F405RG
Type "help()" for more information.

Bought it after kickstarter but maybe it was the same batch, will try to update the board.

Re: Resetting board will not run main.py

Hmm, I don't have pyb.reset or pyb.hard_reset.

pyb.info() or help() do not show the micropython version, how can I see that?

Weren't they included from the start?
