Introduction
BLK202A-S-USB-FB is a display module manufactured by Yangzhou Winsen Electronics Company. It is an LCD character and numeric display module designed for industrial applications. This display module has a 4 x 20 LCD display with two different characters sizes, 8 x 16 and 5 x 8. The module also has a 16 MHz Nvidia Arm Cortex M4 processor and USB interface. The module supports 8-bit, 16-bit and 32-bit addressing, making it very versatile and suitable for a wide range of applications.Application Field
The BLK202A-S-USB-FB display module is ideal for applications where a high-resolution display is needed, such as video monitoring, medical instruments, and industrial control systems. Its large size, clarity, high contrast and speed make it ideal for any device that requires an easily visible display. The module is also suitable for applications that require a high degree of customization, such as fitness tracking or wearable devices. Additionally, its USB interface makes it an ideal choice for computer-controlled devices.Working Principle
The core of the BLK202A-S-USB-FB display module is a Nvidia Arm Cortex M4 processor. The processor is responsible for controlling the display and its various features, such as contrast, brightness, and images. It also handles the communications between the device and the USB port.The processor is connected to the LCD display via the Serial Peripheral Interface (SPI). This is a synchronous serial communication protocol used to transfer data between devices. It allows the processor to control the display, such as the brightness and contrast, as well as displaying images and text.When an image or text is sent to the display via SPI, the processor will convert it from numerical data into information that can be displayed on the LCD screen. This is done by a series of micro-instructions, known as firmware. The firmware will create the appropriate waveforms for controlling the LCD to produce the desired outcome.Conclusion
The BLK202A-S-USB-FB display module is an ideal choice for applications that require a high-resolution, high contrast LCD display. Its large size and clarity combined with its USB interface make it suitable for a wide range of applications, from fitness tracking to medical instruments. Additionally, its Nvidia Arm Cortex M4 processor and SPI interface make it perfect for applications that require customization.
