+In an embedded program, delaying a task is one of the most common actions taken. In an event loop, delays will need to be inserted to ensure

-When handling I/O, software must call functions that block program execution until the I/O operation completes. When running inside of an OS such as Linux, such functions generally transfer control to the kernel so that another task, known as a thread, can be executed if available, or the CPU can be put to sleep until another such task is ready to perform more work. Because an OS cannot presume that threads will behave cooperatively, threads are relatively resource-intensive, and may be forcibly interrupted they do not transfer control back to the kernel within an allotted time. But if tasks could be presumed to behave cooperatively, or at least not maliciously, it would be possible to create tasks that appear to be almost free when compared to a traditional OS thread.

-Async-await works by transforming each async function into an object called a future. When a future blocks on I/O the future yields, and the scheduler, called an executor, can select a different future to execute. Compared to alternatives such as an RTOS, async can yield better performance and lower power consumption because the executor doesn't have to guess when a future is ready to execute. However, program size may be higher than other alternatives, which may be a problem for certain space-constrained devices with very low memory.

 == What is Embassy?
 
 The Embassy project consists of several crates that you can use together or independently:
 
-* **Executor** - The link:https://docs.embassy.dev/embassy-executor/[embassy-executor] is an async/await executor that generally executes a fixed number of tasks, allocated at startup, though more can be added later. The HAL is an API that you can use to access peripherals, such as USART, UART, I2C, SPI, CAN, and USB. Embassy provides implementations of both async and blocking APIs where it makes sense. DMA (Direct Memory Access) is an example where async is a good fit, whereas GPIO states are a better fit for a blocking API. The executor may also provide a system timer that you can use for both async and blocking delays. For less than one microsecond, blocking delays should be used because the cost of context-switching is too high and the executor will be unable to provide accurate timing.

+
+Embassy provides implementations of both async and blocking APIs where it makes sense. DMA (Direct Memory Access) is an example where async is a good fit, whereas GPIO states are a better fit for a blocking API.

 NOTE: A common question is if one can use the Embassy HALs standalone. Yes, it is possible! There are no dependency on the executor within the HALs. You can even use them without async,
 as they implement both the link:https://github.com/rust-embedded/embedded-hal[Embedded HAL] blocking and async traits.
 
-* **Networking** - The link:https://docs.embassy.dev/embassy-net/[embassy-net] network stack implements extensive networking functionality, including Ethernet, IP, TCP, UDP, ICMP and DHCP. Async drastically simplifies managing timeouts and serving multiple connections concurrently. Several drivers for WiFi and Ethernet chips can be found.

+== What is DMA?
+
+For most I/O in embedded devices, the peripheral doesn't directly support the transmission of multiple bits at once, with CAN being a notable exception. Instead, the MCU must write each byte, one at a time, and then wait until the peripheral is ready to send the next. For high I/O rates, this can pose a problem if the MCU must devote an increasing portion of its time handling each byte. The solution to this problem is to use the Direct Memory Access controller.
+
+The Direct Memory Access controller (DMA) is a controller that is present in MCUs that Embassy supports, including stm32 and nrf. The DMA allows the MCU to set up a transfer, either send or receive, and then wait for the transfer to complete. With DMA, once started, no MCU intervention is required until the transfer is complete, meaning that the MCU can perform other computation, or set up other I/O while the transfer is in progress. For high I/O rates, DMA can cut the time that the MCU spends handling I/O by over half. However, because DMA is more complex to set-up, it is less widely used in the embedded community. Embassy aims to change that by making DMA the first choice rather than the last. Using Embassy, there's no additional tuning required once I/O rates increase because your application is already set-up to handle them.

 Interrupts are a common way for peripherals to signal completion of some operation and fits well with the async execution model. The following diagram describes a typical application flow where (1) a task is polled and is attempting to make progress. The task then (2) instructs the peripheral to perform some operation, and awaits. After some time has passed, (3) an interrupt is raised, marking the completion of the operation.
