Compatibility I/O modules

The compatibility modules expose the board's traditional single I2C, SPI, UART, and OneWire services. They are useful for simple scripts and existing code. New applications that need multiple or dynamically attached buses should prefer solaros.buses.

Safe workflow

  1. Inspect status() or allowed(pin).
  2. Use a board-supported bus, pin, chip select, address, mode, and speed.
  3. Check transfer results.
  4. Leave the service in a known state when the script exits.

For external hardware, man buses and man expansion describe the resource-owned path.

Quick reference

Compatibility modules are solaros.i2c info, probe, scan, read_reg, write_reg; solaros.spi status, xfer, read, write; solaros.uart status, baud, is_valid_baud, mode, write, read; solaros.onewire allowed, reset, scan, xfer. Inspect status or allowed first. New multi-bus code should prefer solaros.buses. Modules are package-gated.
