Deep Dive w/Scott: More Merging #adafruit
43Join Scott today as he answers questions from the chat and works on the MicroPython 1.13 merge.
Scott is sponsored by Adafruit to work on CircuitPython. Support them, and by extension me, by purchasing hardware from https://adafruit.com
Chat with me and lot of others on the Adafruit Discord at https://adafru.it/discord.
Deep Dive happens every week. Normally Fridays at 2pm Pacific but occasionally shifted to Thursday at 2pm. Typically goes for two hours or more. Questions are welcome.

16:20 Micropython 8 years old - happy birthday! (April-29)
19:43 adafruit readme on github
20:03 BNO055 project see forums.adafruit.com
21:56 Interrupts/threading MP vs.CP
24:59 - memory related usage
27:25 CircuitPython libs just work cross platform, like using a LoRa RF modem on a RasPi with Blinka.
28:45 Can CircuitPython run on the Adafruit Feather boards? - see circuitpython.org/downloads
29:33 learning regular Python helps learning CircuitPython
31:27 Merge 1.12 completed - pull request
32:10 Thanks Jeff E.
32:35 anyone been able to get circuitpython working on a soft FPGA RISC-V?
33:33 Dan’s pull request for USB stuff!
34:18 - status update ?.merge MP 1.10 ….1.15 into ( CP 7.0 )
38:40 Sublime merge process description
39:48 VS Code
41:48 forking... making a copy and modding from there, and merging you bring in changes from a newer version of what you forked from?
42:49 pycharm ?
43:35 contributing to github guide
43:57 expanding on 1.12 pull request
45:45 merging…
54:04 meld is free tool similar features
56:15 MP_ERROR_TEXT
57:50 using beyond compare right now to compare two 8GB binary files.
59:23 Source Tree, Visual Studio
1:04:30 Is there an Adafruit BMP280 eagle library? - need to check product…
1:07:20 GC collect - assign 0 to support collecting
1:09:20 under 200 files to merge left
1:14:50 assign 0, then gc vs. del for freeing memory
1:17:09 using del() to unimport
1:17:47 Does CircuitPython run any hardware CI to make sure there are no regressions on supported boards?
1:19:35 pairheap - we probably want it :-)
1:26:00 we don’t use mod microsocket
1:28:15 Jeff found places where we don’t have tests…
1:29:12 mp thread
1:31:00 frzqstr.py
1:32:44 in the py folder!
1:36:45 CP has more support in ‘struct’ and turn off non-standard stuff
1:42:35 py/compile.c # emit bytecode
1:45:35 walrus operator? PN_annassign
1:48:50 native mpy files? … emitbc.c # emit bytecode
1:52:25 yes - it’s nice to merge each milestone
1:54:32 py/gc.c
1:57:16 CP has f-string support, MP doesn’t
1:59:59 CP gets full version from github
2:00:30 py/malloc.c
2:02:15 “after I’m done with this, it is not going to compile, that’s now how it works”
2:06:07 py/modstruct.c ( we don’t use it I think )
2:07:10 two spots where we want to say circuitpython…
2:09:12 some things that don’t belong in the py folder…
2:11:50 community broadband…
2:14:25 FCC interested in learning users broadband speeds https://broadbandmap.fcc.gov/#/
2:16:57 py/obj.h (is a big file)
2:19:31 a while ago they changed the capitalizations of things….
2:28:31 six to go
2:32:30 py/objmodule.c - 99 left
