I’m more troubled by the fact these emails are hitting my sendgrid only email address. Is this related to the breach that SendGrid said didn’t happen? I set my account up in 2021 f…

A pin planner- without the code gen of STM32Cube- would be doable as a website. I made a basic one for the RP2350- https://rp2350b.pinout.xyz/ Though STM32Cube has a very different…

I've thought about this on and off for years, trying to find a way to boil the stuff I've learned making Pinouts into some kind of tool. There are a surprising number of pitfalls, …

Once I get the hand of the ESP’s idiosyncratic signal names (I don’t have much experience with them) I should be able to crank them out. But help would be appreciated, thanks - eve…

Nerd snipe successful. (very beta website) https://esp32c5.pinout.xyz

In typical fashion I got nerd-sniped into making an ESP32 C5 DevKit-1 pinout. I've disappeared down a hole of making the perfect SVG for the board art. Will be an interesting exper…

Thanks... urge to build a version for ESP32-C5-DevKitC-1 rising...

Agreed. Click-to-select-related-pins is something I've been experimenting with on a cut-down Raspberry Pi Pinout [1] And code gen is something I'm looking at with the RP2350A pinou…

Agreed. Thanks! I have definitely struggled with making the Pinout spinoffs discoverable- the OG site had ten plus years to bed in.

I recently started building something like this for the RP2350A chip [1], deeply inspired by both STM32Cube and also by avoiding recreating the horror of STM32Cube. I’m currently f…

PIO kinda sorta does this but yeah the Pico could definitely benefit from a more flexible pin mux, since bringing up PIO peripherals is messy. Pico never quite has a function where…

I did something like this called “picopins” (pip install picopins) which gave a CLI ASCII-like pinout with search. ASCII-only really cuts to the meat of the problem though.

Thank you. You’re welcome on both counts!

I was tired of looking in two places when referring to the datasheet for pin functions and locations. This simple one-page website brings the RP2350A's pins, alt functions and note…

I've been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I've since given the Raspberry Pi Pico [2] and Pico 2 [3] micro…

In theory you wouldn’t even need to load firmware- you could just manipulate the relevant registers directly over SWD for the silliest IO expander. In our case it was the only choi…

We (Pimoroni) actually shipped this technique in PicoVision, used to load the “GPU” firmware (an RP2040 used to offload the HDMI signal generation) at runtime- https://github.com/p…

I could believe you feel less latency, but suspect that’s more a symptom of matrix scanning working for the general case rather than being optimised for your layout. Scan with an R…

Well this rang the ol’ memory bells and brought me to Daniel’s Nim drivers for our Pico based products (1). He’s probably the guy to talk to. Not needing a Python wrapper would def…

This sounds like it could port well to an RP2040-based display. Though I am forever battling against its very constrained RAM for network stuff (not helped by MicroPython needing a…

Our crude (actually Pillow’s IIRC) dither has a certain nostalgic appeal to it, but can definitely be bested by other algorithms. I’m still not totally convinced we have a great pe…

I started putting together a Lua-based toy microcomputer [1] using PicoVision and a USB mini B to A adapter to connect a mouse/keyboard. It’s a hacky mess, but it serves as a proof…

A PIO LUT instruction with a 256 entry deep, 32bits wide lookup table would absolutely make my day.
