There are Differential Non-Linearities and Integral Non-Linearities caused by mis-matching of on-die ADC capacitors. INL and DNLвЂќ, and in-datasheet errata вЂњRP2040-E11вЂќ.

Refer to the RP2040 datasheet build-date:, build-version: 150df05-clean, sections вЂњ4.9.3. * Raspberry Pi confirms there is a hardware flaw in the RP2040 ADC. If you will excuse me, IвЂ™ll post some info and links here in my reply to your comment: I assumed it was covered here on Hackaday, but when I searched through the RP2040 posts here I did not come up with anything. The ADC HW bug was discussed widely around February 2021. Posted in Raspberry Pi, Tool Hacks Tagged logic analyzer, pi pico, pico, pulseview, raspberry pi, Raspberry Pi Pico, sigrok Post said: вЂњOne thing to keep in mind is the RP2040/Pi Pico does have a hardware bug (slightly mis-specced internal capacitances) that create ~9LSB non-linearity (0.22% of measurement range) at 4 points.вЂќ If an oscilloscope is what you need and a smartphone is what you have, perhaps youвЂ™ll enjoy the Scoppy firmware for the Pico. WeвЂ™ve covered Pulseview being used in combination with cheap accessible analyzers before - a must-watch if you need to get yourself up to speed on the value they provide to a hobbyist. However, if you need a logic analyzer ASAP, you should follow the caringly offered quickstart guide.

ItвЂ™s likely that youвЂ™ll soon see this driver in a stock Pulseview installation, however, given the submitter-friendly attitude weвЂ™ve witnessed on the sigrok mailing list. The GitHub repository linked above stores the driver files out-of-tree, but provides build instructions together with an easily flash-able uf2 firmware. Compared to the $10 вЂњSaleaeвЂќ clone analyzers we are so used to, this thing boasts 21 digital channels with up to 120 MHz capture speed, 3 ADC channels at up to 500 KHz, and hardware-based triggers. People have been using a Pi Pico as a logic analyzer in a pinch, and now has shared a sigrok driver that adds proper support for a Pico to beloved tools like Pulseview.

Whether youвЂ™re trying to understand why an SPI LCD screen doesnвЂ™t initialize, whatвЂ™s up with your I2C bus, or determine the speed of an UART connection, youвЂ™ll really want to have a logic analyzer on hand. ThereвЂ™s a slew of hardware hacker problems that a logic analyzer is in a perfect position to solve.
