I've got the same error, although I use a Pyboard v 1.1, and it should have one :

Any idea whats wrong? Does it needs to be switched on first or something similar?

Hi pythoncoder,

your solution worked! Thank you very much.

First I tried with 100Ohm, but it didn't work. Then I tried with 50Ohm (5x10Ohm), and this worked!
I will buy a ~50Ohm resistor asap and try again.

Hi Everybody! I have a simple question concerning the pyboard. I want to use it with an external powerbank. It works fine, but the pyboard is just too efficient :mrgreen: and not drawing enough power, so the powerbank thinks it is not used and goes into standby mode after 30 sec (and switch off the ...

I found a solution. Maybe not the best, but it works:
and later, I reset btn_reset = 0 in the main loop:

Hi jimmo,

yes it works!! thank you very much.

but now I get the following problem: on each press, the pin_switchup(pin) function is called many times.. I would like to call it only one. Is there a simple trick to do this?

Thanks in advance,

Hello, thank you very much. Unfortunately I get now the following error: TypeError: function takes 0 positional arguments but 1 were given .. I I still don't know how to do it. I think I miss something... and I don't find any proper tutorial/example to figure it out by myself. Could you give me a ha...

Hi Roberthh, thank you very much for the hint! I read the doc, but I don't really get it how to implement it? Here is what I did, bit somehow it doesn't work (I want to trigger the function switchup()) sw_up = Pin('Y12', Pin.IN, Pin.PULL_UP) sw_up.irq(handler=switchup(), trigger=Pin.IRQ_RISING) Or d...

Hello everybody! NEWBIE question: I want to set up an external button. I should behave exactly like the USR button (I would like to trigger a function when the button is pressed). Here is the code I use to with the USR button: sw = pyb.Switch() sw.callback(switchup) If I try to copy this code to my ...

[SOLVED!] Now I found the solution... 1. unplug the pyboard 2. type: ls /dev/ttyACM* 3. plug the pyboard 4. type: ls /dev/ttyACM* 5. figure out the new device, this is the pyboard (in my case: /dev/ttyACM3) 6. then, use this new device address to connect! sudo picocom /dev/ttyACM3 For some reasons :...

Well, with sudo I don't get the error message, but I can't access to the REPL neither...
And I am in the dialout group.

How can I figure out which process is using the device, and how to stop it?

Thanks in advance,

Vince
