 ## Overview
 
-This bootloader leverages `embassy-boot` to interact with the flash. 
-This example targets STM32 devices with dual-bank flash memory, with a primary focus on the STM32H747XI series. 
+This bootloader leverages `embassy-boot` to interact with the flash.
+This example targets STM32 devices with dual-bank flash memory, with a primary focus on the STM32H747XI series.
 Users must modify the `memory.x` configuration file to match with the memory layout of their specific STM32 device.
 
 Additionally, this example can be extended to utilize external flash memory, such as QSPI, for storing partitions.
 
 ## Memory Configuration
 
-In this example's `memory.x` file, various symbols are defined to assist in effective memory management within the bootloader environment.  
-For dual-bank STM32 devices, it's crucial to assign these symbols correctly to their respective memory banks. 
+In this example's `memory.x` file, various symbols are defined to assist in effective memory management within the bootloader environment.

+//! This example demonstrates some approaches to communicate between tasks in order to orchestrate the state of the system.
+//!
+//! We demonstrate how to:
+//! - use a channel to send messages between tasks, in this case here in order to have one task control the state of the system.
+//! - use a signal to terminate a task.
+//! - use command channels to send commands to another task.
+//! - use different ways to receive messages, from a straightforwar awaiting on one channel to a more complex awaiting on multiple futures.
+//!
+//! There are more patterns to orchestrate tasks, this is just one example.
+//!
+//! We will use these tasks to generate example "state information":
+//! - a task that generates random numbers in intervals of 60s
+//! - a task that generates random numbers in intervals of 30s
+//! - a task that generates random numbers in intervals of 90s
+//! - a task that notifies about being attached/disattached from usb power
+//! - a task that measures vsys voltage in intervals of 30s
+//! - a task that consumes the state information and reacts to it

+//! This example shows some common strategies for sharing resources between tasks.
+//!
+//! We demonstrate five different ways of sharing, covering different use cases:
+//! - Atomics: This method is used for simple values, such as bool and u8..u32
+//! - Blocking Mutex: This is used for sharing non-async things, using Cell/RefCell for interior mutability.
+//! - Async Mutex: This is used for sharing async resources, where you need to hold the lock across await points.
+//!   The async Mutex has interior mutability built-in, so no RefCell is needed.
+//! - Cell: For sharing Copy types between tasks running on the same executor.
+//! - RefCell: When you want &mut access to a value shared between tasks running on the same executor.
+//!
+//! More information: https://embassy.dev/book/#_sharing_peripherals_between_tasks

+//! This example showcases how to create multiple Executor instances to run tasks at

+//!
+//! Low priority executor runs in thread mode (not interrupt), and uses `sev` for signaling
+//! there's work in the queue, and `wfe` for waiting for work.
+//!
+//! Medium and high priority executors run in two interrupts with different priorities.
+//! Signaling work is done by pending the interrupt. No "waiting" needs to be done explicitly, since
+//! when there's work the interrupt will trigger and run the executor.
+//!
+//! Sample output below. Note that high priority ticks can interrupt everything else, and
+//! medium priority computations can interrupt low priority computations, making them to appear
+//! to take significantly longer time.
+//!
+//! ```not_rust
+//!     [med] Starting long computation
+//!     [med] done in 992 ms
+//!         [high] tick!
+//! [low] Starting long computation
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!

+//!         [high] tick!
+//!     [med] done in 993 ms
+//! ```
+//!
+//! For comparison, try changing the code so all 3 tasks get spawned on the low priority executor.

+//!
+//! Connect the i2s DAC as follows:
+//!   bclk : GPIO 18
+//!   lrc  : GPIO 19
+//!   din  : GPIO 20
+//! Then hold down the boot select button to trigger a rising triangle waveform.

+//! This example shows some common strategies for sharing resources between tasks.
+//!
+//! We demonstrate five different ways of sharing, covering different use cases:
+//! - Atomics: This method is used for simple values, such as bool and u8..u32
+//! - Blocking Mutex: This is used for sharing non-async things, using Cell/RefCell for interior mutability.
+//! - Async Mutex: This is used for sharing async resources, where you need to hold the lock across await points.
+//!   The async Mutex has interior mutability built-in, so no RefCell is needed.
+//! - Cell: For sharing Copy types between tasks running on the same executor.
+//! - RefCell: When you want &mut access to a value shared between tasks running on the same executor.
+//!
+//! More information: https://embassy.dev/book/#_sharing_peripherals_between_tasks

+// Example of polling TSC (Touch Sensing Controller) that lights an LED when touch is detected.
+//
+// Suggested physical setup on STM32F303ZE Nucleo board:
+// - Connect a 1000pF capacitor between pin A0 and GND. This is your sampling capacitor.
+// - Connect one end of a 1K resistor to pin A1 and leave the other end loose.
+//   The loose end will act as touch sensor which will register your touch.
+//
+// Troubleshooting the setup:
+// - If no touch seems to be registered, then try to disconnect the sampling capacitor from GND momentarily,
+//   now the led should light up. Next try using a different value for the sampling capacitor.
+//   Also experiment with increasing the values for `ct_pulse_high_length`, `ct_pulse_low_length`, `pulse_generator_prescaler`, `max_count_value` and `discharge_delay`.
+//
+// All configuration values and sampling capacitor value have been determined experimentally.
+// Suitable configuration and discharge delay values are highly dependent on the value of the sample capacitor. For example, a shorter discharge delay can be used with smaller capacitor values.

+//! This example showcases how to create multiple Executor instances to run tasks at
+//! different priority levels.
+//!
+//! Low priority executor runs in thread mode (not interrupt), and uses `sev` for signaling
+//! there's work in the queue, and `wfe` for waiting for work.
+//!
+//! Medium and high priority executors run in two interrupts with different priorities.
+//! Signaling work is done by pending the interrupt. No "waiting" needs to be done explicitly, since
+//! when there's work the interrupt will trigger and run the executor.
+//!
+//! Sample output below. Note that high priority ticks can interrupt everything else, and
+//! medium priority computations can interrupt low priority computations, making them to appear
+//! to take significantly longer time.
+//!
+//! ```not_rust
+//!     [med] Starting long computation
+//!     [med] done in 992 ms
+//!         [high] tick!
+//! [low] Starting long computation
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//! [low] done in 3972 ms
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//! ```
+//!
+//! For comparison, try changing the code so all 3 tasks get spawned on the low priority executor.
+//! You will get an output like the following. Note that no computation is ever interrupted.
+//!
+//! ```not_rust
+//!         [high] tick!

+//! This example showcases how to create multiple Executor instances to run tasks at
+//! different priority levels.
+//!
+//! Low priority executor runs in thread mode (not interrupt), and uses `sev` for signaling
+//! there's work in the queue, and `wfe` for waiting for work.
+//!
+//! Medium and high priority executors run in two interrupts with different priorities.
+//! Signaling work is done by pending the interrupt. No "waiting" needs to be done explicitly, since
+//! when there's work the interrupt will trigger and run the executor.
+//!
+//! Sample output below. Note that high priority ticks can interrupt everything else, and
+//! medium priority computations can interrupt low priority computations, making them to appear
+//! to take significantly longer time.
+//!
+//! ```not_rust
+//!     [med] Starting long computation
+//!     [med] done in 992 ms
+//!         [high] tick!
+//! [low] Starting long computation
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//! [low] done in 3972 ms
+//!     [med] Starting long computation
+//!         [high] tick!
+//!         [high] tick!
+//!     [med] done in 993 ms
+//! ```
+//!
+//! For comparison, try changing the code so all 3 tasks get spawned on the low priority executor.
+//! You will get an output like the following. Note that no computation is ever interrupted.
+//!
+//! ```not_rust
+//!         [high] tick!
+//!     [med] Starting long computation
+//!     [med] done in 496 ms
+//! [low] Starting long computation
+//! [low] done in 992 ms
+//!     [med] Starting long computation
+//!     [med] done in 496 ms
+//!         [high] tick!
+//! [low] Starting long computation
+//! [low] done in 992 ms
+//!         [high] tick!
+//!     [med] Starting long computation
