The LCD2041-R is a display module used to lock and display the mobile terminal working status. The module is part of the Display Module - LCD, OLED Character, and Numeric category. The module features a 16 chalcogenide character LCD display (4 rows, 40columns), four power LEDs and buzzer, four backlight LEDs, and an ATmega328p processor. The module is based on a Fling ATmega2041R processor and includes an ATmega328P, a 4-row, 40-column LCD display, four power LEDs and buzzer, four backlight LEDs, a keypad and an associated firmware. The module is connected by a combination of the four-wire Serial Peripheral Interface (SPI) and the three-wire micro+5V serial bus.

The LCD2041-R display module is designed and applied in a broad range of applications, including commercial and industrial automobile use, medical equipment, industrial applications, tracking systems, and so on. The module allows quick and easy access to data and information, provides a convenient control interface and is also suited for any microcontroller project with a 16-character display. The module features a liquid crystal display that provides a clear graphic display of information, adjustable contrast algorithms, and several display sizes and typefaces to choose from.

The working principle of the display module is based on a combination of Fling’s ATmega2041R processor, the four-wire Serial Peripheral Interface (SPI), and a three-wire motor/5V serial bus. The processor\'s firmware reads a keypad for user input and stores it in a buffer. Instruction are then sent via the SPI bus to the LCD controller to read data and create the characters for display. The backlight LEDs provide illumination for the LCD character display, and the power LED and buzzer allow for sound and light notifications. The processor can also be used to control external devices by sending data and commands through the SPI bus.

The LCD2041-R display module has versatile applications and can be used to control and monitor different electronic devices in a variety of ways. The module is a great choice for automotive use, medical equipment, industrial applications, tracking systems, and other microcontroller projects that require a 16 character display. The module features adjustable contrast algorithms, various display sizes, typefaces, and onboard LEDs for sound and light notifications. Its combination of Fling’s ATmega2041R processor, SPI bus, and an associated firmware enable quick and easy access to data and information. The LCD2041-R display module is a great choice for any microcontroller project with a 16-character display.
