![]() ![]() The microcontroller Du-z listed uses UART to take the parallel connection and converts to USB. Some DIY guides are here:īasically, theses use a microcontroller to take the parallel connection to the HD44780 and convert it to USB (which is a serial connection). If you have a character display and a HD44780 driver, then you will need to build a microcontroller attachment to connect to USB. What do you mean it's serial? The HD44780 is not serial. Straight pin header, male, Single row, 2.Is there a easy way to connect it to usb ?

It’s even able to cycle though a list of screens to show multiple pages of information, very cool. If you want to show some custom data you can write it to text files and have LCD Smartie read and display the content of those files. And they have a number of plugins available. ![]() Things like MP3 song information, system temperatures etc. I used LCD Smartie to drive and control the display. It can’t be placed too far from the computer though since the recommended max length of a parallel cable is 15 ft. The LCD is powered by an external 5 V power supply. All communication is done directly over the parallel port data lines. Almost no external components are needed a few capacitors for voltage stabilization, a trimmer for the contrast adjustment and a resistor for the LED back-light. This very simple module is driven purely by a computer parallel (printer) port. Very simple LCD unit with almost no external components, driven directly by a computer printer port. ![]()
