Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: LCD-09396. This product was retired because we have started making LCDs with the PIC module built into one unit. This page is maintained for historical purposes only.

Description: The serial enabled LCD allows you to control a parallel based LCD over a single-wire serial interface. Included in this product is a yellow on blue 16x2 LCD connected to our serial backpack. The backpack, based around a PIC16F88, takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more.

Communication with SerLCD requires 3.3V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power, ground and RX pins are all broken out to a 3.5mm pitch screw terminal.

SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the backpack to adjust the contrast.

Features:

  • PIC 16F88 utilizes onboard UART for greater communication accuracy
  • Greater processing speed at 10MHz
  • Incoming buffer stores up to 80 characters
  • Backlight transistor can handle up to 1A
  • Pulse width modulation of backlight allows direct control of backlight brightness and current consumption
  • All surface mount design allows a backpack that is half the size of the original
  • Faster boot-up time
  • Boot-up display can be turned on/off  via firmware

Dimensions: 1.425x3.15" - 1" Thick

  • I found the contrast to be below expectations. The LCD can hardly be used without the backlight. The backlight is green, which turns it into a very standard yellow on green. The display works, but consider the ‘All your base are belong to us’ picture a result achievable by professionals only.

  • I’m new to this and found the datasheet unclear and inconsistent about how to clear screen etc.
    Serial.print(0x7C, BYTE);
    Serial.print(0x01, BYTE);
    Just wasn’t doing it!
    Several hours of searching finally answered the question! to clear the screen you use this;
    Serial.print(0xFE, BYTE);
    Serial.print(0x01, BYTE);
    A really useful explanation and more info is to be found here;
