Re: Pico ADC misbehavior
If you measuring a DC voltage or slowly varying DC voltage try a 100nF or 1uF on the ADC input to ground. I wasn't exactly having OP's problem - I was seeing crazy jumps in analog readings on my pico. I thought the only solution was getting a precision voltage-reference input into ADC_VREF, but the...

Re: OneWire Interface
Ok, so I went back to it today, and there was nothing wrong. Of course. I tried the ds18x20.scan() method and it populated the same as the onewire.scan() method. There is nothing worse than an intermittent problem with no explanation. I finally got all the different source files set up to compare wi...

OneWire Interface
I'm having problems deciding if there is a problem with micropython's handling of DS18x20 devices. I cannot find anything regarding this in this forum, nor the web at large, so I figured i'd ask. I was hoping to control a heater with temperature samples from a DS18B20 device. I'm using an RP2040 for...
