Change Note 2024-05-25

Modules SPIdev and UARTdev

• Conceptual and structural clean-up of device set-up.
• See also Device Modules.

Module Terminals

• New exported procedure InitUART, using the updated corresponding procedures in module UARTdev.
• InitUART is just a utility, the UART device can be initialised otherwise via the UARTdev API, to be passed to Open as TextIO.Device.
• Update Open accordingly, which now consistently takes only parameters as defined in TextIO. That is, any TextIO-compatible device can be used in a terminal, not just UARTs anymore.
• Update module Main, including the ones in the example program folders.

Module TextIO

• Add flush functionality to Writer to support buffered output (see example program StringBufOut, below).

Modules Texts and Out

• Add exported procedure for flushing buffered output (see example program StringBufOut, below).

Module LEDext

• Add procedure SetLedBits to address a subset of the LEDs connected to the Pico board.
• Move module to lib/board/rp2040/any, as it is not Pico-specific. Update Astrobe’s library search path accordingly.

Module MCU2

• Add missing register addresses for DMA.
• Add a few missing RESETS_* device id bits.

New Example Program StringBufOut

• The program writes into an output buffer in lieu of directly to a terminal, and then flushes the output buffer “into” the terminal in one go.
• Preparation for using DMA for serial text output.
• See StringBufOut

Example Program SPIrtc

• Change to work with updated module SPIdev, as outlined above.

All Example Programs

• Remove module Main from the respective directories in case the example program does not require a customised version.
