4D Labs μLCD-μLED-μVGA Serial LCD Library

[avenue33]

Please find the latest release of the Serial_LCD library suite.

This library suite works with all 4D Systems screens, uLCD, uOLED and uVGA. It handles text and graphic display, touch, SD-card and sound.


High level library GUI provides label, buttons, menu, dialog box.


High level library Graphics provides clock, gauge and histogram graphics.

Hardware, software and I2C serial connections are managed through the proxySerial library.

As at today, the Serial_LCD library suite is based on Arduino 0023. I'm currently working on an update to Arduino 1.0.

I'd like to take this opportunity to improve the syntax of the functions and make them more consistent.

This means some functions are going to change. For example,

Code: Select all

uint8_t Serial_LCD::gText(uint16_t x, uint16_t y, uint16_t colour, String s)

is going to change for

Code: Select all

uint8_t Serial_LCD::gText(uint16_t x, uint16_t y, String s, uint16_t colour = whiteColour)

with same order: first horizontal and vertical coordinates, then active value, and finally options pre-populated.

What do you think? Answer this quick survey!

Thank you.

Since you are the author, you get to do what ever you want! However, for all the newbees out there, I hope you maintain backward compatibility. There is nothing more discouraging to a newbee when he or she downloads a sketch written for an older version of your library and get's all sorts of errors. Especially since GCC is deeply geeky when it comes to error messages. I still see people asking about problems in sketches they've downloaded which trace back to the changes in the wire library. Since C++ allows you to have multiple definitions of a given function (er, method), you should be able to maintain compatibility and update functionality.

Ideally, sketches written against older versions of your library will just work with the new library.

The new release of Serial_LCD for Arduino 1.0 is available.

Thank you to all those who answered the survey .

A very limited list of functions has a new syntax.

This ensures a better consistency. Non-essential parameters are pre-populated with default values.

Code: Select all

uint8_t tText(uint8_t x, uint8_t y, String s, uint16_t colour=whiteColour)

Note the default value whiteColour for colour.

The Serial_LCD library includes a new graphic: gauge.

On the same screen, an histogram and a gauge display can be combined and share the same data.

Please find the FAQ with answers to the often raised question I receive about 4D Systems screens and the Serial_LCD library suite.

• After resetting a sketch, the screen doesn't respond.
• Which micro-SD to use?
• My screen doesn't light up.
• My screen doesn't play sound.
• My screen doesn't respond when I use faster serial speeds.
• My screen hangs when I use touch.

I decided to go away from Google, which is concentrating too much power over single hobbyists like me. So I closed the accounts for all the products I had.

Up to now, the embedded graphic micro-controller —Picaso or Goldelox— was determined by the type of device —μOLED, μLCD or μVGA.

I faced a dilemma with the μLCD14: although a μLCD, it is powered by the Goldelox micro-controller.

The next major release of the Serial_LCD library suite also features code size optimisation, on top of unification —one single set of libraries for Arduino 23 and 1.0, Wiring and MPIDE— and documentation —PDF and Xcode native docset.

As an example, the memory footprint of the compiled library in charge of the GUI —with label, button, menu, dialog box and slider— has shrunk by 4 KB.

Other libraries are scrutinised under the same process, saving 2 KB out of the Graphics library.

Please find the new release of the Serial_LCD library suite, with

Jul 12, 2012 release 132

• Unified release: one single library for Arduino 23 and 1.0, chipKIT MIPDE and Wiring
• Optimised code: lighter memory footprint
• New graphic: multiple histogram with up to 4 series of values
