在前面GC9项目之前其实单独写过一个HUD，这里就直接把原来的资源弄过，按照现在的想的思路重新搞一次。
HUD北京为透明，这样可以感觉是真的投在玻璃上。HUD上面目前引出的接口如下
/** * @brief fastStart * 快速启动 */ void fastStart(); /** * @brief selfInspection * 自检程序 */ void selfInspection(); /** * @brief powerUp * HUD上电操作 */ void powerUp(); /** * @brief powerOff * HUD断电操作 */ void powerOff(); /** * @brief setLaneKeeping * 设置车道保持 */ void setLaneKeeping(LaneKeep temp = m_LaneKeep_No); /** * @brief setCruiseControl * @param temp * 设置定速巡航 */ void setCruiseControl(bool temp); /** * @brief setSelfAdaptiveCruiseControl * @param temp * 设置自适应巡航 */ void setSelfAdaptiveCruiseControl(bool temp); /** * @brief setSelfAdaptiveCruiseControlDistance * @param temp * 设置距离 */ void setSelfAdaptiveCruiseControlDistance(int temp); /** * @brief setSelfAdaptiveCruiseControlModel * @param temp * 设置自适应巡航模式 */ void setSelfAdaptiveCruiseControlModel(SelfAdaptiveCruiseControlModel temp); /** * @brief setCarSpeed * @param temp * 设置车速 */ void setCarSpeed(int temp); /** * @brief setTurnLight * @param temp * 设置转向灯 */ void setTurnLight(int temp); /** * @brief setDirection * @param temp * 设置导航方向 */ void setDirection(Direction temp); /** * @brief setDirectionDistance * @param temp * 设置距离 */ void setDirectionDistance(int temp = 150);
显示速度的数字仪表部分实现代码如下
