Is that correct? 1:09:35 data descriptors in python https://docs.python.org/3/howto/descriptor.html 1:11:00 Is there a way to make a raspberry pi zero run circuitpython the same way the pico does? I am trying to use usb_hid on the zero but it wont work and pico runs to slow 1:11:39 learn guide bare_metal no os https://learn.adafruit.com/circuitpython-on-raspberry-pi-bare-metal-no-os 1:13:17 USB Host Pico-PIO-USB using PIO https://github.com/sekigon-gonnoc/Pico-PIO-USB 1:19:00 Pico usb host demo 1:21:57 data + and - wires go to uart tx rx pins or any pins ? 1:24:41 github issue 5986 1:26:44 Seniply / colemake configurator qmk.fm 1:27:19 switch to overhead 1:27:45 ​In order to have a Pico or ESP32 communicated with a user space program, is Serial COM the only option? 1:28:29 ​So I followed the guide and have CircuitPython installed (no os) on the raspberry pi zero 2. But it doesn't seem to work. But my pc doesn't detect anything when I plug it in 1:29:14 interested in making a midi usb host. I hope it's not so different than what we are doing here 1:30:00 ETA of usb 2.0 HOST support for HIGHSPEED devices in TinyUSB for original rpi zero (BCM2835) ? (only Teensy 4 chip has both supported for now) 1:31:33 flashing rainbow on hdmi what does that mean? 1:32:27 TinyUSB has USB Host support for HID (keyboard,mouse) and there's a PR for MIDI, but that's it for now I think 1:32:48 pluki (sp) trackball interaction with keyboard 1:34:00 layers on CMK Configurator 1:35:10 running custom code ( not CMK or QMK ) - for colmax keyboard 1:36:02 how long did it take you to make the switch? 1:36:25 if you want more ergonomic keyboard - don’t use QWERTY 1:37:55 Split keyboards are the way to go 1:38:45 keyboardio keyboard ( previous keyboard ) 1:42:58 pimpmykeyboard.com 1:44:50 Keycap families DCS, DSA, and SA Family - ortholinear 1:46:35 keyboard can be CP or HID only 1:47:00 code.py in the keyboard 1:49:15 future refactoring… 1:49:40 “this is a bug” - editing the keyboard code using the keyboard - risky 1:52:25 other standards via and vial 1:52:32 is adafruit going to make a diy vr controller as they HAVE made a vr headset and i have it but im using terrible controllers and i was wondering if you would make some. 1:54:33 keyboard “stages” 1:57:45 any ideas for naming ? 1:58:05 Broadband update / https://wa-law.org / right to repair / share the cities slack 2:05:47 wrapping up / next week also friday / USB Host / https://github.com/adafruit/deep-dive-notes 2:08:30 pet the cat 2:09:14 have a great weekend
