外部多EQ文件切换

u8 curr_eq_index = 0;
const u8 *eq_file_list[] = {
    (u8 *)FLASH_RES_PATH "eq_cfg_hw.bin",
    (u8 *)FLASH_RES_PATH "eq_cfg_hw1.bin",
    (u8 *)FLASH_RES_PATH "eq_cfg_hw2.bin",
};

/**
 * @brief 切换EQ效果文件的接口
 * 
 * @param index 对应eq_file_list效果，0xff:循环切换
 */
void eq_effect_switch(u8 index)
{
    if(index == 0xff){
        curr_eq_index++;
        if(curr_eq_index >= ARRAY_SIZE(eq_file_list)){
            curr_eq_index = 0;
        }
    }
    else{
        if(index >= ARRAY_SIZE(eq_file_list)){
            return;
        }
        curr_eq_index = index;
    }

#if (!TCFG_EQ_ONLINE_ENABLE)
    EQ_CFG *eq_cfg = get_eq_cfg_hdl();
    if(!eq_cfg){
        return;
    }
    eq_cfg->eq_type = EQ_TYPE_FILE;
    int ret = eq_file_get_cfg(eq_cfg, eq_file_list[curr_eq_index]);
    y_printf("eq_effect_switch %d ret %d\n", curr_eq_index, ret);
    // syscfg_write(CFG_USER_DEFINE_EQ_INDEX, &curr_eq_index, sizeof(curr_eq_index));
#endif
}

①找个地方放上面代码
②这里打开
③注意EQ版本和工具生产的EQ文件版本要对应
⑤在下载目录的download.bat文件里加入要添加的.bin文件
⑥测试用例，音乐播放暂时键触发

    case API_MUSIC_PP:
        y_printf("API_MUSIC_PP");
        eq_effect_switch(0xFF);
        // if (state != BT_CALL_HANGUP) {
        //     break;
        // }
        // user_send_cmd_prepare_for_addr(bt_addr, USER_CTRL_AVCTP_OPID_PLAY, 0, NULL);
        break;

⑦如果需要关机保存切换的效果，存一下VM（注意不要在中断里读写VM，VM的ID不要与其他的冲突）

#define     CFG_USER_DEFINE_EQ_INDEX    10

//************************************************//

syscfg_write(CFG_USER_DEFINE_EQ_INDEX, &curr_eq_index, sizeof(curr_eq_index));

//************************************************//

#if (!TCFG_EQ_ONLINE_ENABLE)
    u8 user_eq_index = 0;
    int ret = syscfg_read(CFG_USER_DEFINE_EQ_INDEX, &user_eq_index, sizeof(user_eq_index));
    y_printf("ret = %d, user_eq_index = %d", ret, user_eq_index);
    if ((ret>0) && (user_eq_index >= 0 && user_eq_index <= ARRAY_SIZE(eq_file_list))) {
        eq_effect_switch(user_eq_index);
    }
#endif

2. 触摸按键添加自定义按键方法

①先添加按键判断的宏，以6击、7击，以及3S抬起、5S抬起为例

    KEY_ACTION_SIX_CLICK,
    KEY_ACTION_SEVEN_CLICK,

    KEY_ACTION_HOLD_3SEC_UP,
    KEY_ACTION_HOLD_5SEC_UP,

②触摸流程添加多击判断
③按键转换流程添加抬起判断

    else if (key->event == KEY_ACTION_UP) {
        y_printf("multi_clicks_translate, key->event == KEY_ACTION_UP");
        y_printf("hold->send_5s_msg = %d, hold->send_3s_msg = %d", hold->send_5s_msg, hold->send_3s_msg);
        if (hold->send_5s_msg == 1) {
            key->event = KEY_ACTION_HOLD_5SEC_UP;
        } else if (hold->send_3s_msg == 1 && hold->send_5s_msg == 0) {
            key->event = KEY_ACTION_HOLD_3SEC_UP;
        } else {
            y_printf("no opt");
        }
    }

④添加按键消息

    APP_MSG_SIX_CLICK,
    APP_MSG_SEVEN_CLICK,
    
    APP_MSG_HOLD_3SEC_UP,
    APP_MSG_HOLD_5SEC_UP,

⑤在按键消息处理函数里添加测试用例

#include "classic/tws_api.h"
#include "btstack/avctp_user.h"

    case APP_MSG_SIX_CLICK:
        y_printf("APP_MSG_SIX_CLICK");
        u8 addr[6];
        u8 *bt_addr = NULL;
        if (a2dp_player_get_btaddr(addr)) {
            bt_addr = addr;
        }
        if (tws_api_get_local_channel() == 'L') {
            y_printf("local_channel is L");
            user_send_cmd_prepare_for_addr(bt_addr, USER_CTRL_AVCTP_OPID_PREV, 0, NULL);
        } else if (tws_api_get_local_channel() == 'R') {
            y_printf("local_channel is R");
            user_send_cmd_prepare_for_addr(bt_addr, USER_CTRL_AVCTP_OPID_NEXT, 0, NULL);
        } else {
            y_printf("local_channel is unknown");
            user_send_cmd_prepare_for_addr(bt_addr, USER_CTRL_AVCTP_OPID_NEXT, 0, NULL);
        }
        break;
    case APP_MSG_SEVEN_CLICK:
        y_printf("APP_MSG_SEVEN_CLICK");
        if (tws_api_get_role() == TWS_ROLE_MASTER) {
            tws_play_tone_file_alone("tone_en/normal.*", 400);
        }
        break;
    case APP_MSG_HOLD_3SEC_UP:
        y_printf("APP_MSG_HOLD_3SEC_UP");
        break;
    case APP_MSG_HOLD_5SEC_UP:
        y_printf("APP_MSG_HOLD_5SEC_UP");
        break;
