Dear colleagues, playing half a day with LPC2119 CAN controller, I really halted at problem, that interrupt service routine for CAN message reception does not work. I have a board with LPC2119 (TPN0431AY), crystal, CPU and peripheral frequency equal to 10MHz. It communicates well via CAN with laptop CAN analyser software (both reception and tr

Im using a humidity sensor which is connected to the lpc2119. This sensor is a capacity. In order to mesure this capacity Im using a ne555. The frequency output depend of 2 resistor and the capacity. I would like to mesure frequency on a pin of the lpc2119. I dont know how to Any help please ------------------------------------

I wonder if anyone can help me with the problem we are having with interfacing a peripheral to LPC2119... The issue is that a peripheral (MicroMag 3 from PNI Corp) expects 8 bit command and after measurement transmits 16 bit of data back to master. We have set up LPC2119 in SPI1 master mode, transmit 8 bit command to Micromag 3 and read S1SPDR twice after peripheral signals the end o...

I want to know how to use PWM. I use Keil and LPC2119. Please give me some example code. and told me how to set Frequency, duty ratio and anything that important to know when use PWM. I'd read in datasheet and try by myself for a month but it's still don't work. Please help me. Thank for advance.

hi there, this is my first post here so please be patient with me. i am working with a LPC2119 and i am trying to get the CAN interface working. currently my code is based on the CANFull_V110 example code. Transmitting messages is working like a charm but recieving does not work at all. not one single message gets recieved. not even the ISRs for recieving are called. i tried both CAN1 and ...

Hi, I bought ET-ARM LPC2119 Stamp from Futurelec with the development board earlier. Really nice actually. I have been doing/following all the examples provided by Keil with no problem except things that has interrupt associated with it. I tried to demonstrate the usage of Timer0 but i failed to get the interrupt fires. Looks like something wrong somewhere. I ran out of idea alrea...

Hi all, Anyone that can recommend a good, low cost eval board for LPC2119/LPC2129, (or a similar 64 pin part). I don't want to design my own HW just yet, as it requires a fair bit of RF layout integration :-) Ideally this board will be able to take the parts with memory

Hello. I'm a newb on these forums and on ARM programming, so any help would be appreciated. I've been trying to get my head around interrupts, and i'm not making any progress. I've been looking over the LPC2119 manual, as well as over "The Insider's Guide for Philips" book, and I can't figure out what i'm doing wrong. What I'm trying to do is to generate a fast interrupt via EXTINT1 that wil...

Can anyone tell me why I would use JTAG programming if I can do the same, except debugging, with ISP/IAP? I wrote a very small application (DOS/Windows98, Linux) for automated production programming that works on 68HCs, PICs and the LPC2119 I am testing. ------------------------------------

This causes the checksum of all of the vectors together to be 0. The boot loader code disables the overlaying of the ...
