Detailed Description

This file describdes traces for simavr to collect.

The metadata is stored in the .mmcu section of the compiled ELF binary.

Variable Documentation

const struct avr_mmcu_vcd_trace_t _mytrace [] _MMCU_

Initial value:

= {
    { AVR_MCU_VCD_SYMBOL("PIN_POWER"),    .mask = (1<<PIN_POWER),    .what = (void*)&PINB,  },
    { AVR_MCU_VCD_SYMBOL("PIN_USB"),      .mask = (1<<PIN_USB),      .what = (void*)&PINB,  },
    { AVR_MCU_VCD_SYMBOL("PIN_EN"),       .mask = (1<<PIN_EN),       .what = (void*)&PORTB, },
    { AVR_MCU_VCD_SYMBOL("PIN_SHUTDOWN"), .mask = (1<<PIN_SHUTDOWN), .what = (void*)&PORTB, },
    { AVR_MCU_VCD_SYMBOL("PIN_BOOT"),     .mask = (1<<PIN_BOOT),     .what = (void*)&PINB,  },
    { AVR_MCU_VCD_SYMBOL("STATE"),                                   .what = (void*)&state, },
}

Trace data to collect.

We collect each bit of PORTB (inputs and outputs) separately. We also keep track of the global state variable.

uint8_t state

Current run state.
