LPC-H2294 OLIMEX BLINKING LED CROSSWORKS

Here is my first sample playing around with the LPC-H2294 on Rowley CrossWorks 1.5 . This very simple program just blinks the LED on the header board, very simple. Most of the good sample code that I have found for the LPC is either not for the LPC-H2294 board or not for CrossWroks. So with some extra time I will post sample code of generic routines that you need to interface with this MCU on CrossWorks 1.5 . I could be missing some very good insight with how powerful CrossWorks is and rewritting a messsy wheel, but its all for shits and giggles. The next post on the LPC-H2294 will be a interface for the UART. I plan on getting a good SPI interface so I can do some LCD programming by the end of the month. Then who knows maybe I will create a LPC-2294 controlled robotic killer bunny. It kills anything it comes in contact with. Ok, now how to flash the LPC-H2294 with the PHILIPS LPC2000 Flash Utility V2.2.1. First set both 1 and 2 on Slide switch one (ICSP) to high, this enables the ICSP Programming. Upload the ARM Flash Release .hex file to the flash. This is done by selecting the filename and then clicking on the Upload to Flash button. You could use the Compare Flash button but it never seems to work for me. Once the .hex file has been uploaded to the flash switch Slide switch 2(boot) to the mode you created your binary for and walla.

LPC-H2294 Has arrived. Getting ready to port the SAM7 LCD stuff from jimbo over to the LPC-H2294 Board. Crossworks rocks for ARM stuff on LPC, I dont know why there is so much AT91SAM7 shit going around those boards suck ass!

As you can see LPC ARM7 chips are the way to go!
I can't stand the AT91SAM7S256. Don't get me wrong I would love this chip and header board that I have. I can't stand the fact that there isn't any good software to flash with the ARM-JTAG! OpenOCD is giving me problems with some kind of I/o perms on 0x378. I have read that you can't upload the .elf files with the ARM-JTAG without some software to link into the right memory locations. I'm not exactly sure if this is correct, but how the hell do you create a .bin file on CrossStudio?
The fight for voip is on! Which company can provide the best "free" voip solution without killing the users with poor quality? Gizmo project looks promising, I think in the near further free voip services are going to end up like the other "free" services that you find online. Examples would be blogs, email, web hosting, etc... I'm sure you all know what I mean and are seeing it right now. The small cost would be to hear some small advertising jingle or watch some flash or java applet loading selected images based on who you call?
