Yup, the docs are dead simple, you really don't need a library to control the thing, it just saves on some typing.

Golden rule for newbies: read the docs!
347  Using Arduino / Displays / Re: 4D LABS μLCD-32PT(SGC) 3.2” Serial LCD Display Module Arduino Library on: October 11, 2011, 05:55:17 am
The Serial_LCD library release 9 can now address 3 serial port implementations:
  • hardware serial,
  • software serial, with NewSoftSerial release 11
  • I2C serial, through the SC16IS750

The three classes are derived from the Stream class with specific functions overwritten. Code and example are available on GitHub.

But including all those classes on the proxySerial library —and on the main program— is rather inelegant and redundant.

So the idea would be to declare the serial port on the main program only and pass the objet on to the proxySerial.

What to use : Callback? Reference? Functor? Unfortunately, such advanced concepts are out of my reach.

I greatly appreciate your help!

Thank you smiley .

I placed the code of the library on http://github.com/rei-vilo/Serial_LCD.

I think I figured out what may happen to matinzk.

CAUTION The latest NewSoftSerial release 11 is required for the abstraction layer. Although the library is now named SoftwareSerial, rename it to NewSoftSerial.

Hi!

I faced the same problem of looking for more power a couple of months ago. Remember, the Arduino Due wasn't announced yet.



The Arduino Mega might have been an option, but it's based on the ATmega2560 which remains an 8-bit processor. Price comparison was also a factor.

So I went for the 32-bit board chipKIT UNO32 designed by Diligent and built around the Microchip® PIC32MX320F128.

Main specifications include 80 Mhz 32-bit MIPS, 128K Flash, 16K SRAM, Arduino™ Uno form factor and 42 available I/Os.

The programming IDE is exactly the same as for the Arduino, except it handles both AVR and PIC32-based environments through the selection of the board. It is called mpide for multi-platform IDE. Compatibility is good, even if some AVR-specific libraries require some tweaking.

Read my full review.

Hi!

The Avago ADJD-S371-Q999 / ADJD-S313-QR999 sensor is very powerful, so it requires careful settings.



Please have a look at the review I wrote and the library I've developed.

Enjoy smiley-wink

I received a lot of mails and messages about the Serial_LCD library.

Among them, some deal with basics, as connection, hence this post.



Here's the general layout: an Arduino Uno and the µLCD-32PT(SGC) screen.

Follow to step-by-step guidance so it just works!

Let me answer your questions on the reverse order!

My favourite IC is the I2C 4-channel true colour Avago ADJD-S371 / ADJD-S311 sensor.
How does it compare with this board??  http://item.taobao.com/item.htm?id=10665501753  (I have one of these and I will test it soon..., maybe sell)

The Taos TCO320 convert colour into frequency, one channel at a time to an 8 to 24 kHz range.

Hence you need to ask each channel sequentially and rely on a precise clock to perform a full measure. So the sketch is more elaborate.

I considered this option but went for the I2C Avago sensor instead.

That's a very interesting chip. Where can we get it? Price?? Nice work on your article!
Check at Sparkfun for the IC at US$5 impossible to solder without proper equipment, or the ready-to-use evaluation board at US$15 worth the price.

There are many libraries available for Arduino.

I designed my own to meet specific integration into fischertechnik models.

Hi!

Actually, the Arduino 0022-based MPIDE handles both ATMega Arduino and Microchip PIC32 chipKIT platforms.

As explained in chipKIT wiki,
Quote
Creating the MPIDE and Software Libraries

In order to maintain compatibility with the existing code and resources in the Arduino™ community, it was important to create a seamless transition for the user from their existing Arduino™ boards to the chipKIT™ platform. The core chipKIT™ team contacted experienced Arduino™ IDE developers Mark Sproul and Rick Anderson from the Fair Use Building and Research Labs in Central New Jersey.

In the later half of 2010, Mark Sproul began the arduous task of porting software source files and modifying the existing bootloader from a fork of the existing Arduino™ 0022 IDE while Rick Anderson made changes and improvements to the IDE itself. Rick's efforts resulted in the creation of a modified version of the Arduino™ 0022 IDE that was renamed Multi-Platform or MPIDE as it could be used with both the chipKIT™ boards and existing Arduino™ boards further abstracting the Microcontroller architecture from the user.



I'm currently using it successfully with my Arduino UNO and my chipKIT UNO32 from Diligent.

More on this on my website smiley-wink

Hi,

My favourite IC is the I2C 4-channel true colour Avago ADJD-S371 / ADJD-S311 sensor.



Each channel, red green blue clear, is 10-bit long, so final measure is 40-bit long!

The I2C protocol makes it very easy to use.

For more, take a look at my implementation.

Graphic intensive use of the LCD display with the fast 80 MHz chipKIT board overloads the screen micro-controller.

Especially, sent and received messages overlap and the ACK / NACK protocol is lost smiley-sad.

Hence a solution to protect the serial connection from overload and obtain an nicely synchronised conversation.



The library reaches release 8 with overload protection smiley.

Very nice display, what you are going to do with it ?

GPS related project.

I own the same display. My projects are:
Stepper touch controller

IMU panel

The full library with plain-English functions, touch, buttons and dialog boxes management, sound, data logger, is available here.

In case you and OP haven't heard - there's a new Arduino coming down the pipe, based on ARM - called the Due.

I'm aware of the Arduino Due, but I don't consider one month notice as a roadmap smiley-wink

Lose too much support from your existing or future user base and you will fail.

I fully agree with you: the user base support is the key part of the "Arduino spirit", so to speak.

What interesting with the chipKIT offer is the multi-platform IDE, based on Arduino 0022 with AVR compiling, but expanded to PIC32 compiling.
359  Development / Other Hardware Development / Re: Arduino Hardware Roadmap on: September 21, 2011, 07:04:10 am
Hi!

The problem with the absence of roadmap is a loss of users for Arduino.

I started with an Arduino Uno and wanted more power. Since all the Arduino boards were 8-bit based and the Arduino Due was kept secret, I switched for a chipKIT UNO32: 80 Mhz 32-bit MIPS, 128K Flash, 16K SRAM, Arduino™ Uno form factor and 42 available I/Os.

I'm very happy with my new chipKIT UNO32 board, with enough power, memory and ports for quite a period. The IDE designed by Diligent can address both Arduino ATMega and chipKIT PIC32 platforms. Level of compatibility is good and improving.

Support from Microchip is excellent and very responsive.

So, Arduino and ARM, beware: competitors are coming! smiley-wink

Question pas trop en rapport, mais vu que la carte a été citée... : la chipkit UNO32 se programme avec le câble USB ou autre?

Oui, un câble mini-USB normal suffit. La carte contient un stk500v2 pour le chargement.

Pour plus d'informations, c'est officiellement ici et personnellement là smiley-wink
