Application Note ANBS1.00.09 [Issued date August 16, 2010]

New revision with 16MHz crystal

Since August 2010, ThaiEasyElec has released new revision PCB of BlueScreen board and there are some changes that affect the programming.

First, please notice on the board to identify new revision. Old generation of BlueScreen comes with 20MHz oscillator, but with the latest, 16MHz crystal comes instead.

Even that we are lowering the cost but you will got more since the new revision boards are manufactured with lead-free PCB and lead-free process. Plus with environment coating that protects the board from dust and humidity. Now they’re ready to be put into your products with higher reliability!

Now let’s see how to change the code downloaded from website to maintain correct operations. Only PLL multiplier is needed to be changed from 12 to 15.

For Keil’s uVision: in startup file (LPC2300.s)

With 20MHz:
PLLCFG_Val EQU 0x0000000B -> 20x12x2 = 480

With 16MHz:
PLLCFG_Val EQU 0x0000000E -> 16x15x2 = 480

For Yagarto: in main.c, function InitClock()

With 20MHz:
PLLCFG = (12-1) | ((1-1) << 16);

With 16MHz:
PLLCFG = (15-1) | ((1-1) << 16);

For CrossWorks: in startup file

With 20MHz:
#define PLLCFG_VAL 0x0000000B

With 16MHz:
#define PLLCFG_VAL 0x0000000E

After modification, we have tried our old project on new hardware and we experienced that ADC need lower clock to operate (until now we can’t find any reason). So if you’re using ADC and the MCU hangs waiting for ADC to complete the conversion, try reducing ADC speed.

BlueScreen for 3 compilers!!!

2009-12-24T08:42:00.000-08:00

Hi all,

We have launched 3 in 1 code; Yagarto, Keil and CrossStudio. Just make sure you have the right "#define COMPILER_xxx" for your compiler. See more detail in "Please Read" file in the folder.

Thanks for your all supports and Merry Christmas!!!

2009-12-15T08:33:00.000-08:00

BlueScreen source code, for Keil and Yagarto compiler.
To set compiler, choose your compiler in app_config.h

For Yagarto (used with Eclipse IDE):
#define COMPILER_YAGARTO
//#define COMPILER_KEIL

For Keil:
//#define COMPILER_YAGARTO
#define COMPILER_KEIL

Also add .s file corresponding to compiler. And for Yagarto, include files in includes_yagarto too.

LCD driver migrating from ILI9325 to ILI9328

Since August 2009, the LCD installed on Blue Screen has been changed again. Now let’s don’t care what they are different in physical. There is only one line for source code to be changed. Since both ILI9325 and ILI9328 share the same functions. Only read driver code is different, it’s 0x9325 for ILI9325 and 0x9328 for ILI9328. What we have to do is to initialize the LCD in the same way for both of driver IC;

Search for code below in tslcd_elt240320tp_v1_xx.c (it is at line 269 in original code)

if (driver_code == 0x9325) //ILI9325

Then change to this:

And that’s all. No more code needed to be change.

Awesome!!! - Armaide v2.1: LPC2xxx Oberon-07 Development System

2009-07-23T06:33:00.000-07:00

We got the email from our customer . Wonderful Project !!!!
Thanks Mr. Chris Burrows

If you interested in Armaide v2.1: LPC2xxx Oberon-07 Development System
Please contact to CFB Software
Armaide v2.1: LPC2xxx Oberon-07 Development System
http://www.cbsoftware.com/armaide

Below is the explain of the show from Chris.

"
Watch the Armaide vector graphics processing demo running on a BlueScreen:

The first two images are processed in real time, the second two havebuilt-in delays to show the drawing as it proceeds.

All the code is written in Oberon-07 and was developed using our LPC2xxxdevelopment system, Armaide:

http://www.cfbsoftware.com/armaide

The total executable size (including display drivers) is 17 KB.

The AutoCAD Slide image data file sizes are 5 KB for the Space Shuttle and28 KB for St Pauls. They are appended to the executable using the 'resourcemanagement' feature of Armaide v2.1.

The Oberon-07 compiler that is used in Armaide is an excellent alternativeto the C language for programming. Oberon-07 provides the same sort of highand low-level access and performance that C provides. However, the design ofthe language makes it more capable of detecting a greater proportion oferrors at compile-time and runtime before they have a chance to lead toobscure, difficult to trace, secondary faults.

Bluescreen and Rowley's CrossStudio 2.0!!!

2009-07-18T14:23:00.000-07:00

Hi all,

Again that we tried to to make BlueScreen for all developers. Now we have ported them to CrossStudio 2.0 and should also be used with earlier version. We're posting 3 projects, mp3, test_lib (fill-in form) and keypad in couple of days. For new one who have never tried CrossStudio, evaluate version is available at http://www.rowley.co.uk/crossworks/Downloads.htm . And don't forget to download package for LPC2000. And then, just follow our application note.

The test result compare with Eclipse, the board compiled with CrossStudio is much faster (comparable with Keil).

It's now your turn to try it and you'll say 'What a powerfull compiler!!!'.

2009-06-09T11:42:00.000-07:00

Hi All,

Finally, BlueScreen can be used with GNU and Eclipse. Now we have ported 2 examples, keypad and MP3 player (with multi-font supported). They can run every function as same as compiled with Realview but a little slower, expectually in MP3 example when directory list is updated.

For anyone who have tried BlueScreen or have some questions about it, please feel free to leave us some comments. Thank you in advance.
