前段时间一直被MajdataPlay的外键输入问题困扰:有玩家反映majplay会无征兆地出现拖判和吃音,但是内屏一切正常 因为我是第一次接触游戏开发,IO这方面也完全没经验 一开始我和bb本怀疑是线程调度的问题,即:IO线程时间片被其他线程挤占了,导致IO线程无法及时处理HID设备回报。为了验证这个猜想,我们尝试提高了IO线程的优先级,照旧 接下来我怀疑是我那套框架有问题:majplay是根据上一帧与这一帧的按键状态判断按键是不是"click"。为此我重写了这部分的实现,改进了IO线程与主线程之间的交互,问题照旧....... 到这里我已经怀疑这不是majplay的锅:IO线程没有任何异常,IO线程与主线程的交互没有问题,Note判定逻辑也没有问题,那就是设备确实没有回报给majplay或者设备发过来的回报中按键确实没有按下,但是大佬说hdd没有这种问题.....(人已经快崩溃了,这完全看不透也摸不着,因为我用单片机模拟玩家打高速纵连是完全没有问题的,我在家里用手台测试也没有问题) 到最后,bb本灵光一闪,说有没有可能是led刷新率过高,把按键控制板干爆炸了?我们让大佬把led刷新间隔从16ms改成100ms,吃音问题瞬间没有了,无语了 。。。。。。。。。。。。。。。。。。。。 adx是一个控制板同时管理按键和led,为什么我没有遇到吃音问题呢,因为我的手台不是adx的... #dev

🪐 NASA’s Psyche mission is sending a high-tech spacecraft to the asteroid 16 Psyche, testing a new electric propulsion system called Hall thrusters. Hall thrusters use electricity and magnetic fields to accelerate charged particles (ions) for thrust, offering a more efficient way to travel long distances—demonstrating key technology that could power spaceships to worlds like Ceres or the moons of Jupiter in the future. ✨ #spaceships⚡#propulsion⚡#asteroids⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 ESA’s Hera mission, launching soon to study asteroid Didymos and its moon Dimorphos, is bringing a new kind of space probe—one equipped with autonomous navigation, letting the spaceship guide itself during its close encounters. This technology, inspired by how insects use simple visual cues to avoid obstacles, could pave the way for future spaceships that explore places like Jupiter’s moon Europa or the rings of Saturn independently, relying less on commands from Earth and more on real-time decisions. ✨ #spaceships⚡#technology⚡#exploration⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 The future of interstellar travel may rely on building spacecraft capable of withstanding long-duration journeys across vast distances like the 4.37 light-years to Alpha Centauri. NASA’s Starlight project is studying how powerful ground-based lasers could push small, ultra-light probes to a significant fraction of the speed of light—over 100 million kilometers per hour—enabling them to reach nearby star systems in just a few decades rather than millennia. ✨ #spaceships⚡#technology⚡#exploration⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 The Japanese spacecraft Hayabusa2 demonstrated a glimpse of future spaceship technology by visiting the asteroid Ryugu, collecting samples, and returning them to Earth in 2020. Its advanced ion propulsion system and autonomous navigation allowed it to land and lift off from the tiny asteroid's weak gravity—a feat that opens the door to more complex robotic missions to objects like Bennu and even farther out in the solar system. ✨ #spaceships⚡#exploration⚡#technology⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 NASA's Solar System Ambassador program highlights the rapid development of electric propulsion for future spaceships, like the ion engines used on the Dawn spacecraft. Ion engines work by shooting electrically charged atoms, called ions, out of the back of the spacecraft, allowing for extremely efficient travel to distant worlds such as the asteroid Vesta and the dwarf planet Ceres. ✨ #spaceships⚡#technology⚡#exploration⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 NASA has announced plans for its first nuclear-powered rocket in over 50 years, aiming to test an engine in space by 2027. This new technology, called nuclear thermal propulsion, could dramatically reduce travel time to Mars and distant worlds like Europa by heating hydrogen to generate powerful thrust—making human missions to the outer solar system more achievable than ever before. ✨ #spaceships⚡#technology⚡#Mars⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 Deep space travelers will experience time differently than people on Earth—a mysterious effect called time dilation. If astronauts took a fast journey to the star Sirius (8.6 light-years away) on a spaceship moving near the speed of light, their onboard clocks would run much slower than those back home, so they would age less during the trip—even while years passed on Earth. This real phenomenon comes straight from Einstein’s theory of relativity and shows how speed itself can turn space voyages into journeys through time. ✨ #timedilation⚡#relativity⚡#spaceships⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 Scientists studying the future of interstellar travel are exploring how hydrogen harvested from interstellar space—called "ramjet" propulsion—could one day fuel journeys to stars like Alpha Centauri, located over 4 light-years from Earth. A concept known as the Bussard Ramjet proposes using a huge electromagnetic field to collect hydrogen atoms as a spaceship speeds through space, fusing them for energy in the same way stars do, potentially enabling continuous acceleration across vast cosmic distances. ✨ #spaceships⚡#technology⚡#AlphaCentauri⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 NASA’s upcoming VERITAS mission will send a spaceship equipped with advanced synthetic aperture radar and infrared sensors to Venus, mapping the planet’s surface in detail never achieved before. VERITAS will peer through Venus’s thick clouds to unveil its volcanic terrain and tectonic features, opening a new frontier for robotic exploration in one of the solar system’s most extreme environments. ✨ #spaceships⚡#venus⚡#technology⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 NASA’s upcoming DAVINCI mission is set to test a new kind of spaceship technology as it descends through the thick atmosphere of Venus in the late 2020s. The spacecraft will use a combination of heat shielding and parachutes designed to survive the planet’s crushing pressure and scorching surface temperatures—over 460°C—pushing the limits of materials and engineering needed for future robotic explorers of extreme worlds like Venus and beyond. ✨ #spaceships⚡#technology⚡#Venus⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 Scientists are researching how self-healing materials could revolutionize interstellar travel, allowing future spacecraft bound for distant stars like Proxima Centauri to repair themselves from cosmic dust impacts and radiation damage. These advanced materials are designed to sense and fix tiny cracks or holes automatically, greatly increasing the durability and safety of deep space missions as they travel through the harsh, unpredictable environment between the stars. ✨ #spaceships⚡#technology⚡#innovation⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​
