Published my first product on
@Gumroad: A Pico 2 #USB Streaming Guide - achieve 5.1 Mbps USB throughput from a #pico2 with #tinyusb to a python application on a windows host.

Weird crashes have weirdly resolved themselves after I tidied up some code. Measured 30 frames per sec updating a 480x320, 16bit colour, display with a RPi #Pico2 via SPI using the PIO feature.

And the maths checks out! SPI speed using PIO should be 75MHz. Which makes <eyes roll back whilst doing maths in head> 30.52fps. #electronics

While probing a GPIO pin on my oscilloscope, I noticed it toggled between 2.4V and 3.3V. Using another reference pin, toggling at exactly the same time swinged correctly between 0V and 3.3V

I think I might have damaged a pin on my #rp2350 :( #debugging #signals #embedded #pico2

Looking to turn my #Pico2 in a rudimentary #oscilloscope. Have been checking the ADC's samplerate and tried measuring an ultrasonic distance sensor's echo pulse. Not quite there yet, USB throughput is still a limiting factor.
