Some of you have been kind enough to ask if I am OK (no new chapters for more than a week ...). I can assure you that all is well - expect a number of new and updated chapters in the next few days. This will include a "DVS" chapter, as several people have requested. I've just updated one chapter (Chapter 6 - a large number of changes): http://tte-systems.com/books.php Apart from ...

Can someone point me to a definitive / application reference for the Watchdog circuit used in the LPC2xxx - )one that is better than the user manual for LPC2292) I recently started trying to use the watchdog in the LPC2292. Knowing no better, I decided to feed the watchdog once every time I went round my event loop. I was careful to disable* interrupts before writing 0xAA and 0x55 to WDFEE...

I recently had to assist a user to sort out some obscure development issues caused by functional problems and specification deviations in a Revision '-' LPC2378 MCU.

Are revision '-' items consider to be 'use at your own risk' p...

Hello, did anybody ever try to run a 'fast mode plus' I2C device at a clock rate of 1MHz with LPC2xxx? As the protocol is identical to 'fast mode', I wonder if it can be used with LPC2468. I know that it is a feature with Cortex M3, but it is not mentioned in the LPC2468 manual. Any experience? Henry ------------------------------------

Hi Tom, The RTCK isn't strictly needed. Without the RTCK if the JTAG port works slowly, as is the case of the LPC2xxx, then the JTAG cable/debugger has to put in a delay before it samples the TDO. I'm surprised that companies are selling JTAG cables that require RTCK - the cynic in me says it's a way of getting repeat business. Michael

Anybody here ever seen (or done) an IAP flash programming app that re-loads flash with updated code that the end user downloads from their PC ? I would think one could do this without too much trouble on an LPC2XXX and might even fit into one sector. Un-encryption of the downloaded code would be a benefit as well so code copying wouldn't be so much of a pro
