I am thinking of using an LPC22xx as a single chip micro in an industrial controller board. 2 questions. I assume the device can be used to count external...

Hi , ... The Timers have capture/compare channels, but I haven't looked yet at counting pulses with it. With "encoder signal", do you mean you need to input a...
No, dont need quadrature decoder. Just a simple counter input to count pulses. Capture inputs (normally) are only good for timing the length of a signal. ...

Forget the RTC. It is only useful when the system has been initialized and running. -Bill Knight R O SoftWare On Mon, 01 Mar 2004 20:34:13 -0000, onceinfour...
I understand, I don't think you can count pulses thru a capture channel. The only thing of course is to use an External Int, and to maintain a counter in SW,...

... Hi, the 22xx (as well as the 21xx) do not feature counter inputs (yet) but capture inputs to capture an internal free running timer. The RTC only runs when...

... Hello there, It is certainly more reaasuring to see Philips' presence here. I wonder if you would be able to describe more concisely when the code ...
The LPC2106 user guide (2003 Oct 02 Page 17) describes the operation of the write-back buffer, but does not say what happens if the CPU writes a byte and then...

Philips are broadcasting a webcast on TechOnline.com about the LPC2000 family on March 10th. I'm sure there will be a lot of marketing waffle, but the overview...
Reading through the message archives, I see conflicting information on the SPI SSEL pin. Bill Knight says the SPI SSEL pin must be pulled low for the LPC210X...
I think I know the answer, but just to be perfectly clear.. Is there any way to disable the ETM port and use these pins for other functions when using the...
The purpose of my post was to indicate the SSEL pin must be used and tied to the appropriate level for the SPI to operate. Even if used in MASTER mode. I had...
Hello, i have a few questions about SPI slave (at the moment only general questions): 1) I have a SPI master which uses a SPI clk of 20 MHz or even 25 MHz. Is ...
