Change Note 2025-03-11

Tools

• pio2o uses JSON data to extract PIO program data in lieu of parsing the C-header file.
• Note that this requires pioasm from v2.x of the Pico C SDK, since v1.x does not create JSON output (hence the need to parse C before).
• Use PIO.Program in lieu of procedure parameters to get the PIO program data.
• Also tested on macOS.

Module PIO

• Define PIO.Program to convey the PIO program data from PIO assembly code to Oberon.
• PIO.Program comprises all PIO program data provided by pioasm, as defined in the PIO assembly source file. Not all may be used there.

Example Program PIOsquare

• Update example program PIOsquare to use PIO.Program.
