Which GPIO is the INT pin of the HR3300 in the Li Cheng series? I couldn’t find the definition.
None of our open-source development boards have interfaces connected to the HR3300, so our default drivers are not configured for it. If you have HR3300 hardware, you need to connect it to custom pins on the development board and configure accordingly. The image below shows an old configuration we used previously—you should adjust the settings based on your own connections. The main configuration involves setting up the I2C bus and the interrupt pin.
