Thanks for sharing your solution @dzervas. For anyone in the future implementing SoftwareVbusDetect, it looks like you may need to enable these events in the soft device (can't find anything in the soft device documentation that says what their default state is).
Here's an example where those events are explicitly enabled: https://github.com/matoushybl/air-force-one/blob/9dab9a5785fb3a71890e25806152a8e5846b1d1b/bridge-fw/src/main.rs#L294-L297
And the relevant documentation (at least for my version of the soft device): https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.s140.api.v7.3.0%2Fgroup___n_r_f___s_o_c___f_u_n_c_t_i_o_n_s.html&cp=5_7_4_1_2_7_2_27&anchor=gadf77ee1a740e17981163be1903a96f10

At this point I'm too bored to do a PR but I'll come back
For now to make it work you need:
lazy_static! {
pub static ref VBUS_DETECT: SoftwareVbusDetect = SoftwareVbusDetect::new(false, false);
}
#[task]
async fn softdevice_task(sd: &'static Softdevice) {
info!("SoftDevice task started");
sd.run_with_callback(|event: SocEvent| {
info!("SoftDevice event: {:?}", event);
match event {
SocEvent::PowerUsbRemoved => VBUS_DETECT.detected(false),
SocEvent::PowerUsbDetected => VBUS_DETECT.detected(true),
SocEvent::PowerUsbPowerReady => VBUS_DETECT.ready(),
_ => {}
};
}).await;
info!("SoftDevice task finished");
}
#[embassy_executor::main]
async fn main(spawner: Spawner) {
...
let driver = Driver::new(p.USBD, Irqs, &*VBUS_DETECT);
...
let sd = Softdevice::enable(Default::default());
spawner.spawn(softdevice_task(sd)).unwrap();
}I'm omitting any code covered by the readme
from nrf-softdevice.

this is because you've enabled some interrupt at a softdevice-reserved priority. make sure to follow https://github.com/embassy-rs/nrf-softdevice#interrupts
from nrf-softdevice.

Oh great, now i start missing info in the readme... 😂
Ok so I also use the usb driver so I did the following before even enabling the hardware peripherals and did the timer and GPIOTE priority fix that you describe in the readme
Interrupt::USBD.set_priority(Priority::
Interrupt::POWER_CLOCK.set_priority(Priority::P2);Here are all my enabled interrupts:
Interrupt 0: Enabled = true, Priority = P2
└─ src/main.rs:197
Interrupt 6: Enabled = true, Priority = P2
└─ src/main.rs:197
Interrupt 17: Enabled = true, Priority = P2
└─ src/main.rs:197
Interrupt 39: Enabled = true, Priority = P2
└─ src/main.rs:197
But I still get the exact same panic

POWER_CLOCK is reserved to the softdevice. If you want to use VBUS detect must do it through the softdevice's SoC events, not directly with POWER.

oh so the softdevice exports events instead of interrupts to be able to use such functionality
can you give me an example on how to setup the nrf driver to use events?

commented on June 28, 2024
there's no example (PRs welcome!). You'd do it with this, calling the methods there when the events fire: https://docs.embassy.dev/embassy-nrf/git/nrf52840/usb/vbus_detect/struct.SoftwareVbusDetect.html
