This week's EYE ON NPI is like a Vulcan: no, it doesn't have pointy ears, but it is totally logical! It's the Crouzet Millenium Slim Ultra-Small Logic Controller.
Happy New Year! 2:01:40 Kitteh ! - LIVE CHAT IS HERE! Adafruit on Instagram: Subscribe to Adafruit on YouTube: New tutorials on the Adafruit Learning System:. Next Deep Dive is tentatively on 7 January 2022.
First a code.py that uses the Neopixel needs to be on the Raspberry Pi 1:46:16 Setting up Salea Logic analyzer for neopixel to monitor the Raspberry Pi 1:47:16 It didn’t work, debugging 1:48:03 Todbot: That neopixel analyzer is pretty cool! 1:49:30 print debugging in CircuitPython 1:54:40 Q: Will CP for RPi understand HMD_cvt and HDMI_drive in config.txt so I can configure a 5 inch HDMI LCD from Waveshare? 1:55:26 Back to the broadcom data sheet and debugging continues 1:57:24 Wrapping up and Goodbye for 2021. 1:30:52 Back to implementing Neopixel 1:40:36 What speed should data be sent to the FIFO and how is that controlled? 1:42:22 Let’s see if it builds and works! What could go wrong? 1:44:35 Oops. Scott: A good place to followup is in the #circuitpython-dev channel on Adafruit Discord or open an issue in GitHub.
Perhaps Thach would know more… 21:47 Pi Zero 34:38 NeoPixel on RPi 41:37 Firmware Debugging and Development Tools for projects and contributing to CircuitPython 52:58 Back to neopixel 1:16:33 Where does the Neopixel code live in CircuitPython? 1:20:20 Start implementing Neopixel for the CircuitPython RaspberryPi port 1:30:19 Q: I can’t build today’s CircuitPython latest.

Join Scott as he adds NeoPixel support to CircuitPython on the Raspberry Pi and answers questions. We recommend looking over the product selector at before booking your order - check the Flash, PSRAM and temperature offerings! #deskofladyada #thegreatsearch #adafruit Visit the Adafruit shop online - LIVE CHAT IS HERE!

This is where it pays to check the Espressif datasheet for the specific chip naming *especially* since sometimes the part marking isnt clear. The Great Search - ESP32-S2 chips of all flavors This week's Great Search is about learning from mistakes - in this case I ordered the wrong ESP32-S2 chip for the QT Py S2, because I wasn't paying attention to all the variants.
Finally we also got our 4-layer QT Py ESP32-S2 boards in and put together a prototype to verify the boards came out right (its our first 4 layer). Our rev B of Feather M4 adalogger is in, and we think we've got this one ready to ship. First up we have revised our CP2104 breakout to use the CP2102N as we covered last week, its the next 'generation' of Silabs usb-serial chips.
We had a smashing week of getting through some older prototypes.
