Embassy-rs support for the Vorago VA108xx MCU family

This repository contains the embassy-rs support for the VA108xx family. Currently, it contains the time driver to allow using embassy-rs. It uses the TIM peripherals provided by the VA108xx family for this purpose.

Usage

This library only exposes the embassy::init method which sets up the time driver. This function must be called once at the start of the application.

This implementation requires two TIM peripherals provided by the VA108xx device. The user can freely specify the two used TIM peripheral by passing the concrete TIM instances into the embassy::init_with_custom_irqs and embassy::init method.

The application also requires two interrupt handlers to handle the timekeeper and alarm interrupts. By default, this library will define the interrupt handler inside the library itself by using the irq-oc30-oc31 feature flag. This library exposes three combinations:

• irq-oc30-oc31: Uses pac::Interrupt::OC30 and pac::Interrupt::OC31
• irq-oc29-oc30: Uses pac::Interrupt::OC29 and pac::Interrupt::OC30
• irq-oc28-oc29: Uses pac::Interrupt::OC28 and pac::Interrupt::OC20

You can disable the default features and then specify one of the features above to use the documented combination of IRQs. It is also possible to specify custom IRQs by importing and using the [embassy_time_driver_irqs] macro to declare the IRQ handlers in the application code. If this is done, embassy::init_with_custom_irqs must be used method to pass the IRQ numbers to the library.
