That gain around 600km/s for every volt they are accelerated through. Old CRT monitors wereВ particle accelerator where the accelerating anodeВ turns the electrons into a high speed-beam of electrons. Placing a new frame just before the monitor grabs the latest. But you can also reduce the frame ageВ by rendering more frames faster. Under the right circumstances, you can reduce this time byВ 12.5 ms. The rendering takes timeВ but lets keep it simpleДЄ frame can be 0.000000001 - 16.6666666В ms oldВ in the buffer with a 60 Hz monitor.ДЄ frame can be 0.000000001 - 4.16666666 ms oldВ in the buffer withВ a 240 Hz monitor.ДЄ higher refresh-rate will reduce the maximum time a frame can lay and wait,В before it isВ grabbed and drawn on a monitor. A 60 Hz monitor takesВ the latest frame every 16.66 ms in the buffer and draws it upon itself.В A 240 Hz monitor takes the latest frame everyВ 4.16 ms.

TL DR version - I'd say after a certain point the game engine (larger part?) and displayВ must be the bottle neck if a USB Host Shield,В intercept signals from devices like you described at the beginning of your video (check medium link for more info),В can measureВ button response time avgВ ofВ 3msВ on a PS4 pad over a good bluetooth dongle.ДЄll you get with a high refresh-rate monitor is moreВ draws with a lower buffer latency. so I've seen a fast clicking arduino with a 10.8ms total response time and your quickest mouse response of 13ms total response time, both on 240Hz monitors. So this recent video of yours you've got the Acer FX250Q or A monitor which I couldn't find 3rd party measurements for, anyway you've got sub 14ms response times now.

The a measured 2~3ms g2gВ at certain shades The quickest monitor measured with their own photosensitive diode&oscilloscope scope system,В Asus ROG Swift PG279Q, 3.25ms total display lag The arduino had 10.8ms of total response time Razor naga vs arduino, arduino was 4.4ms quicker despite both being 1000HzВ (1ms)В devices Photosensitive diode vs 1K FPS camera setup, camera was 1ms quicker Wired PS4 controller vs Wireless, measured via USB Host Shield (1ms device), Wireless on avg was 7.3 to 1.8 ms quicker depending on the dongle, coming in at 3ms avg with a good one. I see input lag measured around the internet, The video is kinda crappy, the motion of that hammer moving down towards the mouse could be enough to shake the bench or vibrate it enough for the mouse to wake up from battery saving mode.

So, you can measure the latency between fake click on button and when the click is recognized in the operating system - you'll have wake up latency, transmission, the 1ms polling time in Windows then whatever amount of processing time the driver needs inside Windows. The idea is that a wireless mouse may go to 'sleep mode' to save battery power after a few seconds of no movement, so by shorting the wires to fake a mouse click you're guaranteeing you're not waking up the mouse before the actual click. Would be also interesting to have the mouse locked in place and just short the wires to make the mouse think you pressed the button, without actually touching the mouse. for example light a led or something when click happens) you could have soldered two wires directly under the left click button and use that as a way to detect when click happens or to simulate a click (and also use that as a trigger, for the camera. the specified 9 pF oscillator and 2x18 pF capacitors)Дў) I've incorrectly shielded/grounded my USB Female A plugДЈ) Since I haven't had time to make a 3.3V->5V boost converter, I've been powering the USB port with 5V from my Arduino MEGA 2560 and grounding the MEGA to my circuit.Also to add. What could be causing this problem, or is my problem somewhere else in the circuit?ДЎ) too much capacitance (my 20 pF crystal oscillator + 2x39 pF capacitors vs. I've looked at the USB D+/- signals from both boards with an oscilloscope (see attached image link) and they're all but identical except for the tail end of the waveforms.

I purchased a full size host shield for my Arduino MEGA 2560 to gather control data for debugging, and both it and the dongle work perfectly with the board_qc sketch.

The 'board_qc' sketch passes every test when I run it on my homemade shield (connected to an Arduino Pro Mini 3.3V 8MHz) but then fails with 'USB State Machine Reached Error State' when I plug in a Pluggable BLE dongle. To start, I'm simply trying to recreate the Mini Host Shield, but I'm stuck when it comes to getting the USB data transfer to work. I'm trying to build the USB Host Shield (based on the MAX3421E chip) from scratch since I need to be able to power the Arduino using OTG mode, a premade board will not work for my application.
