Well that’s wild because I had a disagreement with beziers recently and did a similar thing! [1] albeit with more madness and less polish. Driven by the a/s/d/f keys with find edges snap to reference images and curve fitting

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 for reasons I don’t recall and it’s since been deleted&#x2F

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 approach, handles lots of mutually exclusi

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, since there's always some complexity most top

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 - even a canonical list of the pins and functions would be super

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 experiment!

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 pinout [2] where the JSON export would allow someone to

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 failing to not build STM32Cube for Pico though, the idea keep

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 it’s needed.

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!

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 choice. I’d say we’d use UART now but the RP2350 can pretty much

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/pimoroni/picovision/blob/main&

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 RP2040’s PIO [1] and after debouncing I’d challenge you to me

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 definitely help slim down FrameOS into something you could stuf

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 chunk for buffers, an GC bitmap for mark/sweep and som

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 perceptual match for the colours either. The approach to get t

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 of concept. There’s also a herculean work in progress

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

Really interested in putting together some kind of USB host to HID over GATT profile or Bluetooth HID to i2c/UART bridge. We’re (Pimoroni) closing on shipping a dual RP2040 HDMI board (PicoVision) that’s great for bedroom coder style g

I’d be remiss not to mention that we (Pimoroni) sit right at the hacker end of the E-ink scale with stuff like Badger2040W [1] and Inky Frame [2], both of which pair (small and less small) E-Ink panels with the RP2040 microcontroller so you

Bear in mind I’m just reading the product page specs here but if you want me to measure mine I can dig it up!
