LCD and OLED Displays in SimVimX

SimVimX has native support of commonly used character LCDs with 4-bit parallel interface. No any libraries are used, SimVimX firmaware controls the LCD directly. All standard ASCII Characters and a some of custom symbols can be used to display information on LCDs. You can easily assign any data to be displayed in the SimVimX Plugin configuration window.

SimVimX 4-line parallel LCD wiring

Why a 4-line bus architecture is used in SimVimX System for LCD displays, not the serial i2c or SPI?

• It’s faster (because parallel), custom hard-coded without using slow libraries.
• It uses the same 4 common lines that already exist in the system, for all displays, each additional LCD needs only one output pin.
• No need to bother about different address for every device (as I2C needs), or the SPI issues with multiple devices.
• To work with I2c we would need to use not only an i2c library, but also a library for every display type, with all their user-configured options. Or else, we would have to write our own I2C universal program for all displays.

The SimVimX interface is initially designed in such a way that it should not force the user to program something (the firmware code is not accessible for user) and interface should be universal “plug-and-fly”. We don’t use any 3rd-party libraries, the firmware code for every outpu
