Hardware Testing on HALPI2

[mairas]

Implementation Details

• Test on actual HALPI2 hardware:
  • I2C communication with RP2040
  • Analog measurements accuracy
  • Watchdog feeding
  • State machine transitions
  • Firmware upload
  • Shutdown sequence
• Test with firmware versions 2.x and 3.x
• Verify compatibility with Python version behavior

Test Scenarios

• All I2C operations work on real hardware
• Measurements match expected values
• Watchdog prevents system reset
• State machine transitions correctly
• Firmware upload succeeds
• Shutdown sequence works

Acceptance Criteria

• All features work on HALPI2 hardware
• Behavior matches Python version
• No hardware regressions
• Firmware compatibility verified

Caveats

• Requires access to HALPI2 hardware
• Test carefully to avoid damaging hardware or corrupting firmware
• Always have backup firmware available

Dependencies

• All implementation and testing tasks
