Re: Timer example not working
I notice there's a new firmware build out today (29th Dec). Perhaps this might fix it? Where did you find the new firmware? On github, the last commit was on Nov 18th. Cheers, Zoltán You can find the last build of the Wipy firmware as this address : http://www.micropython.org/download/ It's nearly ...

Re: ADC Conversion
Hi, it's probably an issue with the signal conditioning. What's the input impedance to the ADC pin? For instance, the expansion board has a capacitor on the battery monitoring circuit to maintain the value stable while the ADC is sampling. Daniel, Yes, the expansion board ADC input for the Lipo mea...

Re: Timer example not working
Ok, we'll wait. Getting past the op error (by using freq=5) I've run into this before: >>> tim_ch.callback(handler=lambda t:led.toggle()) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: no such attribute >>> dir(tim_ch) ['freq', 'period', 'time', 'event_count'...

Re: registered function on Timerchannel gets not executed
According to some example found in the documentaton, this work like that :
Code: Select all
def stepnext(timer):
pin_step.toggle()
tim = Timer(1, mode=Timer.PERIODIC)
tim_a = tim.channel(Timer.A, freq=700)
tim_a.irq(handler=stepnext)

class Pin – control I/O pins - Documentation
Hello Daniel, The usage models described in the ' class Pin – control I/O pins ' documentation are not correct. Here are two example to include in the documentation and usable with the expansion board. The first one may be : from machine import Pin led_exp = Pin('GP16', mode=Pin.OUT, pull=None, driv...

Re: ADC Conversion
I continue on the same topic for an other issue. It's written in the documentation of the Wipy that the maximum voltage at the input of the ADC is 1.4V. This mean that I should have an ADC reading of 4095 for 1.4V, right ? Practically, if I do a rules of 3 with my actual readings, the full scale vol...
