ODrive VS esp-idf

ODrive perhaps?

Well I dunno, maybe see how ODrive does it

Then maybe just hook everything to an Odrive and maybe add an Arduino or something to tell it what to do - although this also means you'll probably want an encoder at least on the pedalling motor to get accurate position/speed readings at low speed, since pedalling cadence is typically in the 60-90RPM range

If you want speed, use servomotors

This video may interest you, maybe also check this one and check out simpleFOC and/or ODrive

ODrive time?

Look at using some RC brushless motors driven from an ODrive board

You can probably replicate your own with appropriately sized RC brushless motors driven from ODrive boards. The boards can be linked together via CAN bus to communicate with your Arduino equipped with a CAN bus shield.

Thanks for the link! I know about simplefoc, the problem is the hardware. Simplefoc focuses on low wattage motors, e.g. a gimbal motor for a camera. For high wattage application, there's not much hardware available, and none that is affordable. There's odrive, which will set you back ~300$ just for the controller. Other than that, you'll have to go to traditional robotics companies.

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?
