Hello, I'm facing an issue with rp2040-hal and PIO, maybe this rings a bell to somebody: my PIO program does not seem to be able to drive any pins, both `side-set` (2 pins) or `out` (1 pin).
- my pins are all `gpio::Pin<GenericPinIdArgument, gpio::FunctionPio0, gpio::PullNone>`, passed via `pin.id().num` to `PIOBuilder::side_set_pin_base` and `PIOBuilder::out_pins`, I am using `PIO0` indeed
- nothing with `pindirs` in the PIO program (`.side_set` option or `set`)
- the SM is started, not stalling, hitting most/all instructions (validated via RTT)
- reading `pio.dbg_padout().read().bits()` shows bits toggling on and off, but the logic analyzer is not showing any outputs on the pins
- interestingly, `pio.dbg_padoe().read().bits()` (output enable) shows all zeros, but I didn't find a way to "output enable"/"pindir" side-set or output bits. I'm not sure if this there should be ones here or not.
- The pins don't behave as if driven - while the (cheapo, also RP2040-based) logic analyzer shows a low level, it also seems to easily pick up noise, such as from my hand touching the jumper wire.

Does this ring a bell to somebody? Thanks!
