I love making little machines tick—especially the smaller ones! The smaller they are, the cooler they get.
Correct result came a bit faster then expected! Step response measured through RP2350 ADC from 3V3 to Ground. The transition in between is due to the ADC pin being floating for a brief moment in time #pico2 #embedded
ADC readouts on the #pico2 are coming together. Plot below for the visualization of MSB of the adc output (4 bits). Switching input from 3V3 to GND.
Mental note: adc input 3 (or GPIO29) can not be used to measure custom voltages on the #Pico 2 W board as it is already routed on the board to potentially measure Vsys/3.
Spent some time getting a usb bulk data stream working on a Raspberry Pico 2W using TinyUSB.
Biggest hurdles were device/configuration descriptor and realizing tud_task() needs to be called frequently.

Nice to see #bluetooth is still innovating, discovered about "bluetooth channel sounding", increased accuracy and security in distance measurement #embedded
Just trying to configure my pico as USB device and trying to benchmark the 12Mbps USB FS device speed...
Discovered a neat pico 2w detail today! You can safely short Vbus and Vsys when powering the device with only one power source. No need for a Schottky diode in custom designs and gains some efficiency too!
From now on, default short on my breadboard ;)
