raspberry pi lcd module 20x4 factory

The LCD has always been a device that acts as a window in human-computer interaction. For example, the prompt window on some instrument devices, the temperature and humidity prompt box, the device running status monitor, and the prompt screen of the counting device all have LCD figures.

The engineers at Crystalfontz are always working on new projects. Lately, the focus has been on tiny. How small? Recently they have evaluated using a part packaged in 0.4mm pitch 9-pin BGA, 1.3mm x 1.3mm: They are also looking at a 16-pin package that is 3mm x 3mm. The amount of power and complexity that … Read more Micro Tech

When working with a 20×4 character LCD, you might be surprised to see the controller set to 2-line mode: Write_To_LCD(COMMAND,0x38); //SET 2 LINE,5*8 FONT Why would a 4-line LCD’s controller be set to 2-line mode? It has to do with the way the LCD glass is laid out. Essentially the display is the right and … Read more FAQ: Why does the initialization code for a 20×4 LCD specify 2-line mode?
