Re: OSError: accelerometer not found

I've got the same error, although I use a Pyboard v 1.1, and it should have one :o :
https://store.micropython.org/product/PYBv1.1H

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

Re: Prevent powerbank to go into standby mode

Hi pythoncoder,

your solution worked! :D 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.

[SOLVED] Prevent powerbank to go into standby mode

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 ...

Re: Custom (external) Button

I found a solution. Maybe not the best, but it works:

Code: Select all

btn_reset = 0
def pin_switchup(pin):
    global btn_reset
    if btn_reset == 0:
        btn_reset = 1
        switchup()
and later, I reset btn_reset = 0 in the main loop:

Code: Select all

while True:
    btn_reset = 0
    ... (functions and time sleeps)

Re: Custom (external) Button

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,

vince

Re: Custom (external) Button

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...

Re: can't connect to REPL

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.

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

Thanks in advance,

Vince
