Re: Shield for Z-Uno

(...) No protection - we just turn it on/off. Why do you need protection if the wiring is correct? True! I need it, when the wiring is incorrect ;) Maybe the mosfet is so powerful, it can survive a short circuit and drag the supply down...? If I would make my own RGBW I would use "Smart Low Side Po...

Re: Shield for Z-Uno

RGBW = short circuit protected? With current measurement?

Select the frequency in the board settings [arduino menu), it defaults RU and you are probably EU or US

Re: Z-uno is running much slower on PC power than on charger

Although I am not the OP I have been following this with interest and I would like to thank you for your thorough investigation and workaround! BTW never heard of such a behaviour! I learn something every day...

Re: Z-uno is running much slower on PC power than on charger

Here is a piece of code I use in my FLiRS sketch: // Force all pins to output, with some exceptions, // notably the input pin and the serial ports if // debugging has been enabled. This saves power. for (i = 0; i <= 6; i++) pinMode(i, OUTPUT); // Leave Serial1 pins alone if they are used for debuggi...

Re: Z-uno is running much slower on PC power than on charger

Can I ask you to consider what I said anyway? I do understand what you are doing. I understand you disable interrupts and what pins you use. But your Z-Uno runs a lot of code that is invisible to you. Also, you do not get to decide which peripherals get initizialized, and how... Controlling interrup...

Re: Z-uno is running much slower on PC power than on charger

Long shot... Could it be some MCU pins pick up noise? That alone does not not explain what you see, the noise should also trigger something like an interrupt. Also I think all inputs default to weak pull-up, but to be on the safe side, could you set all unused pins to output mode?
