|\ \ | |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 810: Takes care of power for nRF USB devices r=Dirbaio a=huntc Modifies the usb-serial example to illustrate how to setup USB for situations where the USB power can be detected and removed. Gaps: ~~* No support for the nrf-softdevices as yet, although this should be possible via another constructor.~~ * No support for the nrf5340, although this should be possible via USBREG. The change is tested and appears to work. Some notes: * There's an existing field named self_powered as a UsbDevice field. It doesn't ever appear to get set. I'm wondering if this field is intended to signal that a device has the nRF VBUS power situation or not. I'm not presently using it. * The new PowerDetected event is generated on the bus initially in situations where just new is used i.e. without power management, including on STM. We can therefore rely on this event always being generated. Old description: ~~EnabledUsbDevice is a wrapper around the `UsbDevice` where its enablement is also subject to external events, such as `POWER` events for nRF. It is introduced generically to support other platforms should they also require external signaling for enablement.~~ Co-authored-by: huntc <[email protected]>
| * Trait for UsbSupplyhuntc2022-07-095-90/+24
| | | | | | | | Eliminated a signal by using a simpler trait method that returns whether VBus power is available. Also includes a UsbSupply that can be signalled for use with the nRF softdevice. Includes the requirement for waiting for power to become available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It currently contains whoever was first to write some code for the crate, even if many more people have contributed to it later. The field is "sort of" deprecated, it was made optional recently: https://rust-lang.github.io/rfcs/3052-optional-authors-field.html Due the the reasons listed there I believe removing it is better than setting it to generic fluff like "The Embassy contributors".

* | Rename channel to mpmchuntc2022-06-129-9/+9
|/ | | | I've renamed the channel module for the MPMC as mpmc. There was a previous debate about this, but I feel that the strategy here avoids importing `channel::channel`. The change leaves `signal::Signal`, but I think that's ok. It is all a bit subjective of course. The bottom line for me is that I really like the term mpmc - it means something to me and aligns with broader naming e.g. in Tokio.

Given that the HSI runs at 16 MHz and the HSE range is 4-48 MHz, the PLL is the only way to reach 64 MHz. This commit adds `ClockSrc::PLL`. The PLL sources from either HSI16 or HSE, divides it by `m`, and locks its VCO to multiple `n`. It then divides the VCO by `r`, `p`, and `q` to produce up to three associated clock signals: * PLLRCLK is one of the inputs on the SYSCLK mux. This is the main reason the user will configure the PLL, so `r` is mandatory and the output is enabled unconditionally. * PLLPCLK is available as a clock source for the ADC and I2S peripherals, so `p` is optional and the output is conditional. * PLLQCLK exists only on STM32G0B0xx, and exists only to feed the MCO and MCO2 peripherals, so `q` is optional and the output is conditional. When the user specifies `ClockSrc::PLL(PllConfig)`, `rcc::init()` calls `PllConfig::init()` which initializes the PLL per [RM0454]. It disables the PLL, waits for it to stop, enables the source oscillator, configures the PLL, waits for it to lock, and then enables the appropriate outputs. `rcc::init()` then switches the clock source to PLLRCLK. `rcc::init()` is now also resonsible for calculating and setting flash wait states. SYSCLCK < 24 MHz is fine in the reset state, but 24-48 MHz requires waiting 1 cycle and 48-64 MHz requires waiting 2 cycles. (This was likely a blocker for anyone using HSE >= 24 MHz, with or without the PLL.) Flash accesses are now automatically slowed down as needed before changing the clock source, and sped up as permitted after changing the clock source. The number of flash wait states also determines if flash prefetching will be profitable, so that is now handled automatically too.
