Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[unreleased]

Chip selection is not enforced anymore, but advised through documentation. This makes using the HAL in libraries a lot easier.

GPIO API: Interrupt, pulse and filter and set_datamask and clear_datamask APIs are now methods which mutable modify the pin instead of consuming and returning it.
Simplified PWM module implementation.
All error types now implement core::error::Error by using the thiserror::Error derive.
InvalidPinTypeError now wraps the pin mode.
I2C TimingCfg constructor now returns explicit error instead of generic Error. Removed the timing configuration error type from the generic I2C error enumeration.
PinsA and PinsB constructor do not expect an optional pac::Ioconfig argument anymore.
IrqCfg renamed to InterruptConfig, kept alias for old name.
All library provided interrupt handlers now start with common prefix on_interrupt_*
RxWithIrq renamed to RxWithInterrupt
Rx::into_rx_with_irq does not expect any arguments any more.
filter_type renamed to configure_filter_type.
level_irq renamed to configure_level_interrupt.
edge_irq renamed to configure_edge_interrupt.
UART interrupt management is now handled by the main constructor instead of later stages to statically ensure one interrupt vector for the UART peripheral. Uart::new expects an optional InterruptConfig argument.
enable_interrupt and disable_interrupt renamed to enable_nvic_interrupt and disable_nvic_interrupt to distinguish them from peripheral interrupts more clearly.
port_mux renamed to port_function_select
Renamed IrqUartErrors to UartErrors.

Add downgrade method for Pin and upgrade method for DynPin as explicit conversion methods.
Asynchronous GPIO support.
Asynchronous UART TX support.
Asynchronous UART RX support.
Add new get_tim_raw unsafe method to retrieve TIM peripheral blocks.
Uart::with_with_interrupt and Uart::new_without_interrupt
A lot of missing defmt::Format implementations.

Improve and fix SPI abstractions. Add new low level interface. The primary SPI constructor now only expects a configuration structure and the transfer configuration needs to be applied in a separate step.
Added an additional way to read the UART RX with IRQs. The module documentation provides more information.
Made the UART with IRQ API more flexible for future additions.
Improved UART API result and error handling, added low level API to read from and write to the FIFO directly

Fixes for SPI peripheral: Flush implementation was incorrect and should now flush properly.
Fixes for SPI example
Fixes for RTIC example

Added va41620, va41630, va41628 and va41629 device features. A device now has to be selected for HAL compilation to work properly
Adaptions for the UART IRQ feature which are now only implemented for the RX part of the UART.

Small fixes and improvements for ADC drivers
Fixes for the SPI implementation where the clock divider values were not calculated correctly
Fixes for UART IRQ handler implementation
Add new IRQ router initialization method irq_router::enable_and_init_irq_router. This method also sets the initial values of some registers to 0 where the datasheet and the actual reset value are inconsistent, which can lead to weird bugs like IRQs not being triggered properly.

Added basic DMA driver
Added basic EDAC module
Added bootloader and flashloader example application
Added NVM module which exposes a simple API to write to the NVM memory used for the boot process
