The earlier LPC2xxx ARM processors require a bootloader update in order to protect the code from being read through ISP. We created a free update tool that is suited to reprogram any number of LPC2xxx microprocessors quickly and fool proof. The update tool provided by Philips works just fine, but only for engineers and the update job is quite tedious.

With the rising interest in Forth, we have decided to make a demo system for Philips LPC2xxx CPUs. I had a couple of hours spare today, so a first cut is now available. You need 64k Flash, 16k RAM and a 10, 12, or 14.7 MHz crystal and a terminal emulator at 115200 baud. The distribution includes multitasking, floating point and a manual! http://www.mpeforth.com/arena/lpcforth.zip P...

Hi all, I am looking for the same thing now. When we connect with our jlink we get a unique serial number back so it IS present somewhere.

Dear all, I would like to know if the lpc2xxx owns a serial number that uniquely identifies the device itself from any other device worldwide (I don't mean the part number, that identifies the device class, such as LPC2138 or LPC2366...). I need to use this serial number as a sort of "device address". If the serial number exists, where can I find it? Is it allocated somewhere in the ...

Hi All, I want to get Ogg / Vorbis decoder running on LPC2xxx (preferably LPC2368) but I can't find any good information on (successful) port of Ogg / Vorbis decoder on ARM7 or Cortex-M3 core. I am just aware that the size of embedded RAM may be an issue since Ogg / Vorbis needs bigger RAM for decoding than MP3 format, for example. I prefer to get the decoder running in the internal S...

Hi, I seem to have problems to understand the PWM (although it's not the first time I've set one up for the LPC2xxx family). I run the uC with 72MHz and have set the PCLK for PWM0 to divide by 8. So I would expect to get a 300 Hz signal (with a duty cycle of 50%) out of P3.16, but in fact I get 290 (???) Hz, I don't understand why. In the specific case it's not a problem not to have ...
