Hi, I want to replace my current Atmega128L project (running at 8MHz) with a LPC2114 (also to be run at 8MHz). My motive of doing this is that LPC2114 is more...
... I just checked the total supply current taken by a '2106 flashing a single LED on my board. The board was supplied with 5.1 V from four NiMH cells. At 60...
Robert, I ran some side-by-side comparisons on the first vs. the second versions of delay that you posted. Because I know there is call overhead I just put the...
... Unfortunately, yes. If the delay gets small enough there will be a problem. This should be detectable by calibrating the timer at startup (thus the...

I used 15 for COUNTS_PER_US. Are you implying that setting leaving CLOCK_SPEED at 10000000 and COUNTS_PER_US at 10 would have no difference? (I haven't...

Hello, two hints: 1) Please restart the ISP software on PC after each trial. Bug ? 2) You need a reset pulse on RST, not a constant level ! When you don't use...

Is there any way that we can test to see if the LPC210x is actually in Flash Programming mode? Can we test a pin configuration on the device to determine if it...
Another thought - are you sure that you don't have a poor solder joint on the LPC chip? It might be worth inspecting them all very carefully; I prod them with...
One other thing I haven't seen mentioned here yet. You do have P0.14 pulled low when you are programming? Robert " 'Freedom' has no meaning of itself. There...
... CLOCK_SPEED is a target speed for the timer. The startup for the timer routines sets the prescaler to get the timer as close to CLOCK_SPEED as it can...
Yes. We definitely had P0.14 pulled low while programming. We tried various combinations of things but primarily it included (1) supply power to the device,...
