Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

SD/MMC reading/writing with C SDK
There is https://github.com/raspberrypi/pico-extras/tree/master/src/rp2_common/pico_sd_card which is SDIO based, and works for reading/writing sectors, but very bare bones prototype atm.

A Closer Look at Raspberry Pi RP2040 Programmable iOS (PIO)
I've just been getting to grips with the PIO, they are a lot of fun to program. Whilst the instruction set is very limited with only enough memory for 32 of them you can do some pretty sophisticated things. A key part of the flexibility is the ability to execute incoming data as instructions. You can stream in a mixture of data and instructions via the DMA, the PIO separates the two and uses the instructions to modify execution so a simple loop becomes a lot more flexible. You can easily sync several of them up to. The scanvideo library: https://github.com/raspberrypi/pico-extras/blob/master/src/c... which is for producing video signals (like VGA) on the fly with scanlines supplied by the CPU is a good example of what's possible. You can have multiple scanline PIO running at once, each decoding a compressed RLE format including transparency and it composes them all together on the fly.
If you've ever played one of the Zachtronics games (in particular Shenzhen IO) it feels like the programming in one of those games. Tight constraints but major possibilities when you think about it for a while.

ESP32S3 ability to change wakeup interrupt in wake stub/ulp coprocessor program?
For returning to deep sleep from the wake-up stub you can take a look at how it is done in https://github.com/espressif/esp-idf/tree/master/examples/system/deep_sleep_wake_stub

GC9A01 vs ILI9341 for M5Stack AtomS3 LCD - both work, which should I use?
I found the spi_lcd_touch example and flashed it, and it seems to run fine with either ili9341 or gc9a01 drivers selected (although both are mirrored, and one has the colours inverted compared to the other - both of which I assume are things I can fix in either driver).

I2C Interrupt
If that's the case: You register a GPIO as event source and make a task waiting for it, that then just performs the I2C-transaction. Follow this example https://github.com/espressif/esp-idf/blob/master/examples/peripherals/gpio/generic_gpio/main/gpio_example_main.c

ESP-IDP and pytest markers for supported targets
IDF contains stuff like https://github.com/espressif/esp-idf/blob/master/pytest.ini and https://github.com/espressif/esp-idf/blob/master/tools/ci/idf_pytest/constants.py which are not part of the pytest-embedded package.

Unveiling secrets of the ESP32: creating an open-source Mac layer
ugh.. arduino.
Better to start with ESP-IDF, there's a pretty full featured well documented web server, and a lot more.

ESP32-S3 Usb host hid
Hi, I have device ESP32-S3-DevKitM-1 and i want to catch keystrokes from keyboard. I tried using this https://github.com/tanakamasayuki/EspUsbHost and example from espressif https://github.com/espressif/esp-idf/tree/release/v5.1/examples/peripherals/usb/host/hid/main but when i connect keyboard it is just connecting and disconnecting. Can anyone help me with this?
