circuitpython VS esp-idf

As another point for those interested, it (to my knowledge) is currently the ONLY implementation of a scoring machine that the firmware for the device is written in Circuit Python. which gives this unit an advantage when it comes to any and all multi tasking that the unit may need to do.

The barrier to entry has never been lower. Last night I prototyped some code in Python on my Mac to talk to a Bluetooth peripheral, and then had ChatGPT translate it to Arduino C++ code for a $5 ESP32 which mostly worked on the first go.

You can even run Python on microcontrollers these days. See Adafruit's https://circuitpython.org for which they publish modules for many (almost all?) of the sensors they sell. The modern microcontroller frameworks hide much of the complexity of Wi-Fi, Bluetooth, filesystems, etc. so you can do complicated things with minimal effort. You can really cobble something together in an afternoon.

The Pico runs CircuitPython and uses Adafruit's HID library to emulate a keyboard. It's also possible to emulate a mouse and a gamepad (there are some experiments for gamepad emulation in experiments).

Asked your question in the adafruit discord and they said there's no HT1632c library for circuit python yet. There is a library for micropython. You can request to have it ported from the Micropython library I linked to by opening a feature request in the Circuit Python Github. That would be your best option for now or attempt to port the library yourself.

Microcontrollers can run Python now https://circuitpython.org/

I'm aware of two versions of Python for microcontrollers. Micro Python and Circuit Python

I tried to look in https://github.com/adafruit/circuitpython/tree/main/shared-bindings at audiocore, audioio, an audiomixer looking for a way to access the sample counter manually but I have no clue what I'm looking at :(

Try CircuitPython 8.0.3. The commit log has a couple networking changes for the Pico. My MQTT client seems to have fewer connection issues though they could be a fluke https://github.com/adafruit/circuitpython/compare/8.0.2...8.0.3

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

You can find the examples here: https://github.com/espressif/esp-idf/tree/master/examples

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).

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

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.

ugh.. arduino.

Better to start with ESP-IDF, there's a pretty full featured well documented web server, and a lot more.

i've looked over the the ble peripheiral example https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/nimble/bleprph/README.md and i see it's using

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?
