Re: PWM outputs simultaneously

After some research I have concluded the following. The reason for my question in the first place was that I hade the impression that there were only two timer channels. That is not the case. Each of the four timer timers have two timer channels. With that information and the wipy pinout it is clear...

Re: Network configuration with static DHCP lease failing

Yes I know I can give it a static IP but it is more practical to use a static DHCP lease because one often implement and test in one environment but use it in another. *** Problem solved *** The router provides static DHCP lease to other computer on the net without any problems. However this got me ...

Network configuration with static DHCP lease failing

Hi My router has DHCP enabled and it is also configured with WiPy's macid to provide a static DHCP lease 192.168.10.42, but when the WiPy negotiate the IP adress it gets 192.168.10.160. Is this a know bug, is static DCHP lease feature not implemented or something else? Statement wlan.ifconfig() or w...

Re: Accidently downloaded wrong file when updated fw and safe mode doesn't work

PROBLEM SOLVED Apparently the power from the USB (hub) was limited probably due to unfinnished USB negotiation. Consequently the 3.3v was around 1.5v and the CPU didn't work. By using a mains connected USB power supply, safe mode was entered correctly and erronous files were removed from /flash/sys ...

Accidently downloaded wrong file when updated fw and safe mode doesn't work

Hi I accidently downloaded wrong firmware ( e.g. a directory with files). Safe boot doesn't work, there is no LED blinking when GP28 is connected to 3.3v when exiting reset and 3.3v is disconnected from GP28. The wipy is on the expansion board and is powered by USB. Any suggestions? Is it possible t...

Re: How can pwm timers be synchronized

You can't really control which channels go to which pins, but the mapping is shown here: http://docs.micropython.org/en/latest/pyboard/quickref.html (click on the picture for a bigger verision). For example, TIM2_CH1 is on pin X1, TIM2_CH2 is on X2, TIM2_CH3 is on X3 and TIM2_CH4 is on X4. So those...

Re: How can pwm timers be synchronized

Thanks.

Lets say that I use one timer.
If the output are 2 channels from the same timer then they'll automatically be synchronized.
How can the above be accomplished?
E.g how do I assign each channel to each pin to one timer?
