I'm sucessfully using the Philips ISP tool for flashing the LPC2106. The program seems to be flashed correctly and it's working so far. However, I'm always getting an verify error if I try to verify (ISP tool Verify button) the just programmed SW. Could anybody advice? (hopfully there is no similar thread here, I didn't find anything)

Ashling provide a timer interrupt example which demonstrates how to handle nested interrupts, the VIC and timers etc. If anyone is interested I can post it to the files section. I've been falling behind on posts lately so apologies if some one has answered this already.... The following source snippet is taken from the file... /* This program initiates two timers, (Timer0 and Timer1), to go off at TIMER0_INTERVAL TIMER1_INTERVAL (#defines) intervals respectively. Both Timer0 and Timer1 interrupt handler takes half of the interrupt period to execute. Timer0 is configured as a higher priority interrupt than Timer1. Since it occurs more often that Timer1, it will periodically become a nested interrupt (interrupts Timer1). Whenever the Timer1 interrupts, it turns on P0.4 while the interrupt handler executing. Whenever the Timer0 interrupts, it turns on P0.5 while the interrupt handler executing. Whenever the Timer0 interrupts Timer1 (i.e. nested condition), it turns on P0.6 while the interrupt handler executing. */ Hugh @ www.ashling.com/support/lpc2000/ [Non-text portions of this message have been removed]

In the flash buffer screen download your HEX file, perform a vector calc, and save the hex file back. It should then verify OK. Richard --- In lpc2000@yahoogroups.com, "r_bottleneck" <r_bottleneck@y...> wrote:

Richard , thanks for the answer. But possibly I was not precise enough. I'm using Philips LPC2000 Flash Utility V2.2.1. There I can not find something similar you mentioned. --- In lpc2000@yahoogroups.com, "Richard" <richas@y...> wrote: > > In the flash buffer screen download your HEX file, perform a vector > calc, and save the hex file back.

I haven't seen it. I would like to look at this. thanks, David
