AM32 电调学习–main()

零、相关参数

startup_max_duty_cycle 启动阶段最大占空比

          if (input >= 47 && (zero_crosses < (20 >> stall_protection))) {
                if (duty_cycle_setpoint < min_startup_duty) {
                    duty_cycle_setpoint = min_startup_duty;
                }
                if (duty_cycle_setpoint > startup_max_duty_cycle) {
                    duty_cycle_setpoint = startup_max_duty_cycle;
                }
            }

throttle_max_at_low_rpm 400(2000)
throttle_max_at_high_rpm

    throttle_max_at_low_rpm = throttle_max_at_low_rpm * TIMER1_MAX_ARR / 2000; // adjust to new pwm frequency
    throttle_max_at_high_rpm = TIMER1_MAX_ARR; // adjust to new pwm frequency

char RC_CAR_REVERSE = 0; // have to set bidirectional, comp_pwm off and stall
// protection off, no sinusoidal startup

 if (RC_CAR_REVERSE) { // overrides a whole lot of things!
        throttle_max_at_low_rpm = 1000;
        bi_direction = 1;
        use_sin_start = 0;
        low_rpm_throttle_limit = 1;
        VARIABLE_PWM = 0;
        // stall_protection = 1;
        comp_pwm = 0;
        stuck_rotor_protection = 0;
        minimum_duty_cycle = minimum_duty_cycle + 50;
        stall_protect_minimum_duty = stall_protect_minimum_duty + 50;
        min_startup_duty = min_startup_duty + 50;
    }

desync_check 每6step置1
filter_level 判断过零的次数

一、初始化

1. 初始化外设

    initAfterJump();

    initCorePeripherals();

    enableCorePeripherals();

2.设置参数获取

    loadEEpromSettings();

    EEPROM_VERSION = *(uint8_t*)(0x08000FFC);
#ifdef USE_MAKE
    if (firmware_info.version_major != eepromBuffer[3] || firmware_info.version_minor != eepromBuffer[4]) {
        eepromBuffer[3] = firmware_info.version_major;
        eepromBuffer[4] = firmware_info.version_minor;
        for (int i = 0; i < 12; i++) {
            eepromBuffer[5 + i] = firmware_info.device_name[i];
        }
        saveEEpromSettings();
    }
#else
    if (VERSION_MAJOR != eepromBuffer[3] || VERSION_MINOR != eepromBuffer[4]) {
        eepromBuffer[3] = VERSION_MAJOR;
        eepromBuffer[4] = VERSION_MINOR;
        for (int i = 0; i < 12; i++) {
            eepromBuffer[5 + i] = (uint8_t)FIRMWARE_NAME[i];
        }
        saveEEpromSettings();
    }
#endif
