Module hal 

Minimal hardware abstraction for IoT hosts.

Host firmware implements these traits and registers matching FFI callbacks. The simulated implementation below is used for desktop demos and tests.

Structs

SimulatedHal

Desktop/simulator HAL: 32 virtual GPIO pins + a tick counter for delay.

Traits

Adc

Delay

Gpio

Functions

builtin_adc_read

adc_read(channel) → int raw

builtin_delay_ms

delay_ms(ms) — simulated; advances the HAL clock only.

builtin_gpio_read

gpio_read(pin) → bool

builtin_gpio_write

gpio_write(pin, high) — pin: int, high: bool

sim_drive_pin

Test/demo helper: force an external pin level.

sim_elapsed_ms

Test/demo helper: read simulated elapsed ms.

sim_set_adc

Test/demo helper: inject a simulated ADC reading.
