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.

nanoprintf VS callback_printf - a user suggested alternative

- Nanoprintf – The smallest public printf implementation for its feature set

DOOM! on the #emfcamp TiDAL badge
It turns out that DOOM expects a little more POSIX compliance from it's C library than Micropython provides, in particular the printf implementation is lacking many features. The good part is that because I'm building an entirely separate binary application, I can use someone elses printf, and finally, after a lot of pain, it runs!

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?
What are some alternatives?
printf - Tiny, fast, non-dependent and fully loaded printf implementation for embedded systems. Extensive test suite passing.
arduino-esp32 - Arduino core for the ESP32
defmt - Efficient, deferred formatting for logging on embedded systems
MicroPython - MicroPython - a lean and efficient Python implementation for microcontrollers and constrained systems
printf - Tiny, fast(ish), self-contained, fully loaded printf, sprinf etc. implementation; particularly useful in embedded systems.
WiFiManager - ESP8266 WiFi Connection manager with web captive portal
doomgeneric - Easily portable doom
WLED - Control WS2812B and many more types of digital RGB LEDs with an ESP8266 or ESP32 over WiFi!
lfbb - A Lock Free Bipartite Buffer Library written in standard C11
Unity Test API - Simple Unit Testing for C
callback_printf - callback_printf allows the implementation of portable sprintf, snprintf, vsprintf and vsnprintf like output functions. The code includes wrappers for those functions. It supports all formats of the C 11 standard. wchar_t arguments and strings are printed as UTF-8. It's pretty fast, threadsafe and has no dependencies to other libraries.
