The RFID card reader is easy to operate and has a fast card reading speed. If it is a standard HID device, there is no need to install a driver. The card number can be read in any edit box (for example: Notepad, WORD and other text editing software). This function is suitable for expanding functions on existing software without making any modifications to the original software;

6 17
Modbus is a serial communication protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). It has since become a de facto standard communication protocol in industry and is now one of the most commonly available means of connecting industrial electronic devices.

18
+ AiP1948/AiP1944 is a dedicated LED display driver controller IC with a 3-wire serial interface, supporting common-cathode 16 segments × 16 digits or 24 segments × 8 digits, and a 16×2 key matrix scan. It integrates MCU digital interface, data latch, RC oscillator, and other circuits, making it widely suitable for various LED panel applications.

29
+优点
30
+
31
+1、AiP1948/1944可驱动较多LED灯珠，最高可达16*16=256颗LED灯珠；
32
+ 1. AiP1948/1944 can drive a large number of LEDs, up to 16×16 = 256 LEDs.
33
+
34
+2、AiP1948管脚KEYINT为按键中断输出，平时为高电平，有按键被按下时，在键扫周期内出现低电平脉冲；
35
+ 2. The KEYINT pin on AiP1948 provides key interrupt output; it is normally high, and when a key is pressed, a low-level pulse appears during the key scan cycle.
36
+
37
+3、AiP1948/1944与AiP1628指令兼容，程序移植简单。
38
+ 3. AiP1948/1944 is compatible with AiP1628 instructions, making program migration simple.

+## About WS2812:
37
+
38
+**WS2812** is a set of control circuit and lighting circuit in one of the smart external control LED light source. Its shape and a same 5050LED lamp beads, each element is a pixel. Pixels contained within an intelligent digital interface data latch signal shaping amplification drive circuit further includes a high-precision internal oscillator and programmable 12V high voltage constant current control section, effectively ensuring the color pixel light highly consistent.
39
+
40
+NRZ data protocol uses a single line of communication, pixel after power-on reset, DIN end receives data transmitted from the controller, the first sent over 24bit pixel data is extracted first point, to the internal pixels data latch, the remaining data processing circuit through the internal plastic shaping amplified through the DO output port begins forwarding to the next cascade of pixels, each pixel through the transmission of a signal to reduce 24bit. Pixel using automatic shaping forwarding technology, so the number of pixels of the cascade unrestricted signal transmission, only limited by the signal transmission speed requirements.
41
+
42
+LED has a low voltage driving, high energy saving and environmental protection, brightness, scattering angle, consistency, and ultra-low-power, long life and other advantages. The control circuit is integrated in the LED above the circuit becomes more simple, small size, installation more convenient.

-## About WS2812:
37
-
38
-**WS2812** is a set of control circuit and lighting circuit in one of the smart external control LED light source. Its shape and a same 5050LED lamp beads, each element is a pixel. Pixels contained within an intelligent digital interface data latch signal shaping amplification drive circuit further includes a high-precision internal oscillator and programmable 12V high voltage constant current control section, effectively ensuring the color pixel light highly consistent.
39
-
40
-NRZ data protocol uses a single line of communication, pixel after power-on reset, DIN end receives data transmitted from the controller, the first sent over 24bit pixel data is extracted first point, to the internal pixels data latch, the remaining data processing circuit through the internal plastic shaping amplified through the DO output port begins forwarding to the next cascade of pixels, each pixel through the transmission of a signal to reduce 24bit. Pixel using automatic shaping forwarding technology, so the number of pixels of the cascade unrestricted signal transmission, only limited by the signal transmission speed requirements.
41
-
42
-LED has a low voltage driving, high energy saving and environmental protection, brightness, scattering angle, consistency, and ultra-low-power, long life and other advantages. The control circuit is integrated in the LED above the circuit becomes more simple, small size, installation more convenient.

30
-
31
-1、AiP1948/1944可驱动较多LED灯珠，最高可达16*16=256颗LED灯珠；
32
- 1. AiP1948/1944 can drive a large number of LEDs, up to 16×16 = 256 LEDs.
33
-
34
-2、AiP1948管脚KEYINT为按键中断输出，平时为高电平，有按键被按下时，在键扫周期内出现低电平脉冲；
35
- 2. The KEYINT pin on AiP1948 provides key interrupt output; it is normally high, and when a key is pressed, a low-level pulse appears during the key scan cycle.
36
-
37
-3、AiP1948/1944与AiP1628指令兼容，程序移植简单。
38
- 3. AiP1948/1944 is compatible with AiP1628 instructions, making program migration simple.
