Deep Dive w/Scott:

Join Scott as he discusses #CircuitPython2022, answers questions and chats with ladyada. Support Scott and Adafruit by purchasing hardware from https://adafruit.com Chat with me and a lot of others on the Adafruit Discord at https://adafru.it/discord. Deep Dive happens every week. Normally Fridays at 2pm Pacific. Next week is on Friday. All notes are available on GitHub with links into the videos. Thanks to @askpatrickw and @dcd for making and maintaining the notes: https://github.com/adafruit/deep-dive-notes/ 0:00 Getting Started 3:44 welcome 4:30 camera product mode - microprocessors running circuitpyton 9:17 CP 2022 planning review / introduction 12:30 First blog https://blog.adafruit.com/tag/circuitpython2022/ 14:10 Plans for time off in April - maybe Aug-Oct 16:50 Initially BLE on ESP work 17:00 https://blog.adafruit.com/2022/01/13/scotts-circuitpython2022-tannewt/ 22:39 difference from Arduino, difference from ESP? 23:50 Reading out display data in hardware testing. 25:00 BitmapSaver library can save a screenshot. Then CPython code running on a PC can use PIL to compare it with "known good" copies of the image. 24:42 updates in UF2 repo for display 26:55 Python easy to read? 28:05 Arduino Leonardo-type board with built in Bluetooth. I want to build a Bluetooth Macropad, but I can't find any documentation that helps me. Do you know where can I go to find this? 29:38 USB Host / would love Pi 400 self contained 30:55 Async Networking 31:13 Testing 31:24 tracking “regressions” - things that used to work - github issues labels 33:4Are regressions board or port specific, or are they general regressions 34::52 hoping non-iDevices will get some love for BLE workflows. I've been unable to get code.circuitpython.org working on neither Android or PC 35:22 Android and iOS updates to older apps 36:30 Maybe the community can identify "Port Champions" (or maybe the chip mfgers can step in here) 37:45 Automation and testing 38:41 Rosie-ci in adafruit github 39:42 sommersoft RosiePi repo https://github.com/physaCI 40:43 ,,, using Python to develop API for the ESP family of hardware? 41:40 Is there anything that Gerry does other people could easily replicate for testing? 42:22 What is the timeline for ESP32-S3 gets Arduino support https://github.com/espressif/arduino-esp32/issues/5594#issuecomment-1001514885 43:00 RPi CP baremetal question for you: are Pi3 and/or Pi400 on the map? 45:00 Any pointers/examples of OTA update of CP devices? 46:42 thoughts on simulated hardware for testing 47:44 P400's C port works for gadget mode I think 49:07 This would only replicate what CP “thinks” is displayed on the screen. What about knowing if there is a bus error like we saw on this?: 49:40 not a priority, but any more thoughts on allowing either FS access to the OTA partitions if folks want, or a way to disable OTA to reclaim more flash space for those that want? 50:27 OTA update process 51:30 is OTA exclusive to ESP? 52:29 IDF support ( table posted to discord at 2:48 PST ) 53:15 switch to desktop / learn guide / Circuitpyton-on-raspberry-pi-bare-metal-no-os 55:50 github repo pull requests pr 5858 56:35 pr 5662 58:45 ​Do you have a ESP32-S3-DevKitC-1-N8R8 yet? I got one but it has Octal PSRAM so builds online don't work yet. Hope it becomes a build target. 1:03:20 downloading the latest CP 1:04:26 Authy two factor authentication demo! 1:05:20 wifi on the S3 https://github.com/espressif/arduino-esp32/issues/5594#issuecomment-1001514885 1:06:00 Cat woke up :-) 1:07:00 split out target specific configs pr 5853 1:08:18 make board menuconfig 1:09:44 switch cp to core 1 on S3 pr 5860 1:11:00 Blinka mascot 1:11:50 grokked - slang for understood 1:12:39 Lady Ada dialed in 1:16:40 grok, ping, foobar, and other lang 1:18:37 Lady Ada on screen 1:19:17 HDMI output from microcontrollers 1:20:30 HDMI on pico 1:23:00 https://github.com/Wren6991/PicoDVI 1:25:00 retro look 640x480 by doubling 320x240 1:25:40 use rPi, since FPGAs are unavailable 1:27:00 composite video 1:29:20 PS2 keyboards 1:29:50 BRAM = Block Ram 1:30:00 ML on Raspberry pi 4 - demos and learn guides 1:31:20 TensorFlow vs TensorFlow Lite 1:32:30 ML is statistics in Disguise 1:37:08 Lady Ada signed off 1:38:30 Access to high res camera on raspberry pi ? 1:39:20 Add floppy IO - pr 5832 1:40:22 not getting past the rainbow screen - perhaps GDB could help 1:42:20 caught up on discord 1:43:30 Touch TFT - can we remove it ? 1:53:00 Minute with NimBLE ( espressif.com ) 1:59:00 WiFi workflow discussion - web REPL 2:00:00 difference between sockets and ports 2:02:50 Deep Dives notes auto publish in a few hours 2:03:16 housekeeping wrap-up - next week deep dive on S3 2:04:10 2pm Friday next week 2:04:43 Pet the cat 2:05:23 thanks again
