When doing some experiments with IO expander support for the Pimoroni Yukon, I discovered that the
#ifcheck inmachine_pin_cyw43.conly checks thatMICROPY_PY_NETWORK_CYW43andMICROPY_HW_PIN_EXT_COUNTare defined.This is a reasonable assumption for the Pico W, but causes conflicts if someone (such as myself) wants to attach an external IO expander to their Pico W and have its pins appear as
Pinobjects.This PR addresses this by adding the additional checks for
defined(CYW43_GPIO) && CYW43_GPIO == 1tomachine_pin_cyw43.cletting board builds include wireless but separately choose whether the external IO pins come from the cyw43 or not.The long term solution of course would be to allow for multiple external pin types, but that feels like a bigger discussion, and is more than I currently require anyway.
