Dear Ladies and Gentlemen, I have to develop a very safe CAN Bus application that have to resume its work after a short circuit on the CAN Bus in real time. I have developed a CAN Bus Application with up to 40 CAN Bus Members on a Line, and it works very very well. All Controllers are Philips LPC2129. A few days ago, I simulated a short circuit on the CAN Bus lines with a duration of a

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.

Hello to you all, doing my first post here... The Philips LPC 21xx user manual carefully explains about pclk <-> cclk relation and vpb divider, but doesn't say whether there is any upper limit on pclk... Does anyone know if pclk can safely run at same speed as cclk (vpb divider=1), even if cclk is set at max, that is 60mhz on the LPC 2119

Does anyone (or Philips Techs) know the max input current leakage of the ADC channel input pins? The LPC2148 datasheet says that the input leakage current is max 4uA, but I am thinking that this MAY apply just to the digital signal pins. We are trying to use one of the ADC channels in conjunction with a very accurate voltage divider for determining battery voltage for a battery powered app

This posting reports results of a quick investigation into the boot loader and CRP (Code Read Protection).

The supposed evidence is not even worthy of the label circumstantial evidence. It is a trivial exercise to step through the boot loader with a debugger, bu...
