Elijahg,

You're right about selecting the right channel for the right audience.

I'm posting on both Xcode-related forums —of which Stack Overflow for very specific questions about the Xcode 4 template— and embedded computing related forums.

The idea is Arduino users may be interested in using Xcode and Xcode experts may have some tricks to exchange.

Thanks to this strategy, the Wiring and LaunchPad platforms are now supported by embedXcode. I hope adding more platforms may help raising interest on this project.

There are so many things one could dream about: built-in serial console, integrated help, debugging, closer integration of the tool-chains, ...

Critical Decision Ahead

Most of the open points on embedXcode are about Xcode, especially keywords on the template.

Despite numerous calls for help, they're still unresolved. The Xcode template remains undocumented and there's no sign of openness from Apple. Apple seems to restrict Xcode to OS X and iOS platforms only.

So I'm considering to change for another IDE, with NetBeans as most probable solution. It's open, and documentation is available.

What do you think?

Yes, you need the programming cable from 4D Systems and upload the SGC firmware.

Warranty Note: PmmC or 4DGL programming should only be carried out using any one of the 4D Programming modules (4D Programming Cable, uUSB-MB5, uUSB-CE5). Any malfunction because of custom or third party USB to Serial converters or Serial(RS232) to Serial(TTL) level converters will void the warranty.

Which version of the screen are you using: SGC or GFX?

My library only applies for SGC.

Connect the RESET pin of the screen to a digital pin of the Arduino.

Check RX and TX are correctly connected:

Arduino RX <- screen TX
Arduino TX -> screen RX

Try this example with Serial3 (pins 14 & 15) and pin 4:

Code:
#include "Arduino.h"
#include "Wire.h"
#include "Serial_LCD.h"
#include "proxySerial.h"

// --- Arduino mega2560 - hardware serial
ProxySerial myPort(&Serial3);
Serial_LCD myLCD(&myPort);

void setup() {
  Serial.begin(19200);
  Serial.print("\n\n\n***\n");

  Serial3.begin(9600);
  myLCD.begin(4);
 
  myLCD.gText(25, 25, "String", whiteColour);

  delay(1000);
  myLCD.off();
}

void loop() {
}

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.

The new website is embeddedcomputing.weebly.com/
Dedicated Serial_LCD section is at embeddedcomputing.weebly.com/serial-lcd.html
Code is back on GitHub at github.com/rei-vilo/Serial_LCD
My Twitter is twitter.com/rei_vilo

See you there!

New releases add Wiring and LaunchPad support.



embedXcode • Apr 05, 2012 release 7 • Wiring and LaunchPad platforms added
mpideXcode • Apr 05, 2012 release 10 • Wiring and LaunchPad platforms added

Code is here and documentation there.

Both build and upload have been successfully tested on Wiring S and LaunchPad msp430g2452 boards.

Energia is the Processing-based IDE for the LaunchPad platform.

I have over a dozen libraries and support for 0023 and before is a pain. 

I plan to drop support for anything before 1.0.  The downloads for old versions will be available but I won't add features or fix bugs.

Is this a reasonable approach?

I think so. A code with #include statements everywhere is just impossible to read and maintain.

Unfortunately, I'm also using a chipKIT UNO32 and the IDE is still based on the 0023 repository, so it's adding confusion.

That's the purpose of the poll!
370  Development / Other Software Development / Which Version of Arduino IDE Are You Using? on: April 01, 2012, 06:33:13 am
As at today, there are two versions of the language:

• Arduino 0023, Wiring 1.0 build 100, chipKIT MPIDE 0023, based on the Wiring repository
• Arduino 1.0 alone, based on a new repository

Unfortunately, differences between both are real.

This makes the maintenance of my 4D Systems μLCD-μLED-μVGA Serial_LCD Library Suite really difficult and is a major issue for my embedXcode project, Xcode for Arduino and other boards with Processing-based IDEs.

Thank you for answering this poll!

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.

Read the FAQ!

Except for proxySerial and Serial_LCD which contain each one big class, the granularity for high level libraries is at item level.

Gallery: class Gallery
Graphics: classes gClock, gYaw, gPitch, gRoll, gHistogram, gGauge
GUI: class button and functions dialog, menu, label

Maybe using classes / objects isn't the most efficient way from a size point of view, but it provides clean and robust code.

Truth is, I've already a taste of the Arduino Due with the PIC32-based chipKIT UNO32, 32-bits 80 Mhz 128 kB.


Arduino UNO left, and chipKIT UNO32 right.

Thanks for the accolade!

Yes, size may be an issue. For that reason, I keep a modular approach.
  • proxySerial and Serial_LCD are required, whatever the final application.
  • Graphics, Gallery and GUI are optional.

Correct me if I'm wrong, but unused functions aren't included in the final built hex file.
Code: (makefile)
-ffunction-sections -fdata-sections

I experienced memory limitations with my Arduino Uno so I bought a mega2560.
374  Using Arduino / Displays / Re: 4D Systems μLCD-μLED-μVGA Serial_LCD Library Suite on: March 24, 2012, 08:59:21 am
Please find the new releases of the Serial_LCD library suite:
• for Arduino 0023 and chipKIT 0023: fixed issue linked to Arduino mega2560 uploader bug
• for Arduino 1.0: with all libraries, including the new photo Gallery library and examples.

Use your screen as a image gallery: pictures and video!

Documentation, tutorials, examples and code are available at 4D Systems μLCD-μLED-μVGA Serial_LCD Library Suite.
