VGA32 VGA ESP32 PSRAM Module V1.4 Controller PS/2 Mouse Key

Detailed Information About The Product:

PS/2 full key without PS/2 supports real full-key no punching. What does that mean? To put it simply, the system can recognize as many keys as you press on the keyboard at one time. For Usb keyboards, it is relatively lacking. Although some Usb keyboards also claim to have this function, they are generally made of signal good.
PS/2 has lower latency The interface is different, and the working principle of the device is naturally different. usb works by polling the device.
For example: What does your computer ask your mouse goodon for? The mouse goodon will respond by saying, move left. Similar to this question and answer method. PS/2 sends interrupt requests through the system. The mouse goodon of the PS/2 will actively interrupt the current activity of the CPU, and then tell the computer what I want to do. Compared to the USB method, PS/2 has lower latency, and the response time will be faster in actual use.
Better PS/2 compatibility The current win7 system is still loved by many players. However, during the installation process of the win7 system, the USB driver is not integrated, which leads to the failure of the normal use of the USB mouse goodon. The PS/2 mouse goodon is not limited. Although some seem to be to use a USB mouse, the good effect is really mediocre, and a significant delay can be seen. Colour:black
