You can test for yourself whether it is open drain. When the processor is not in reset, use a 1k pull-down resistor on the pin. It the output goes toward and...

Hi Martin and Marcus, Swapped +1.8V and +3.3V is a real bummer. I've also added a level shifter to convert the clock from +3.3V to +1.8V. A suggestion to use...
Hmmmm.... Looks like you are right. I checked this on my two different 2368 CPUs. One is running at 48MHz and another is running at 72 MHz. Regardles of...
... Strange isn't it? Sure seems like the kind of thing that ought to be documented somewhere. I set up another timer with the prescaler set to 0, just to...
Hi, I want to use an ULN2003A (got suggested here a while ago as a good LED driver). Can anyone confirm that the ULN2003 works with the 3.3V output from LPCxxx...
Hi Bob, Just a clarification as I've recently just delved into this. The CPU is restricted to 60MHz or below as stated. The 48MHz CPU speed comes about if you...
... To follow up, accessing the APB (LDR) takes 13 cycles across the board, except for the RTC area where it takes between 25-28 cycles. That's pretty extreme...
... LPCxxx I/O pins? Yes, that is what we are using. (at 25C ...) ULN2003A needs a maximum of 2.4 volts (for 200 ma) and the LPCxxxx generates at least 2.9. ...
... The 60MHz limit applies to execution from FLASH. All my tinkering is done while running from RAM so I go for the 20% speed boost. :-) I realize I'll ...

hi, Ashwin I met a issue of stability in LPC VirtualCom. For example: i open HyperTerminal and send "1" to device to light LED. It's ok. Then i send "1"...
I have LPC-P2124 Protoype board made by olimex and an ulink2. My question is: If I push the reset in the board while I debuging with ulink2. this generate a...
Hi, thanks for the answer, this sounds good. Does it matter whether we use the ULN2003A or the ULN2003AI (second one has a serial resistor of 2.7k on series...

Nah, I'm not nit-picking. Some typos just strike me as funny. As for "femalefunctions", do you really want your code getting moody and snapping at you for no...
