I'm having a bit of a problem getting started in using interrupts in C with LPC2129 and GCC. The search function seems to be broken at this moment so I'm starting a new thread. My problem is, there are so many interrupt sources, how can I tell from within the IRQ or FIQ routine where my interrupts are originating from? Would be great to see some example of interrupt code that uses multip...

I'm using the Keil uVision IDE tool and the LPC2129. My question is about setting up single edge hardware PWMs. Someone previously posted the following code: REG(PWM0_PR)=0x0000; //no prescaler - one cpu clk is one PWM clk REG(PWM0_MCR)=0x0002; //Reset timer counter register

Hello Group, I am using a development board with LPC2129. I downloaded the sample code i.e BlinkyCAN which came along with Kiel and Jlink package. The sample code is able to send and receive the CAN messages. However, if I put the breakpoint in Receive interrupt, the break point is never hit. May I know the reason? Can I any give me a sample code which has got simple CAN receive interrupt ...

I'm using the LPC2129 and Keil Tools. The purpose of the code is to interrupt on the receipt of a single byte of data and assign data to its value. The interrupt seems to work however data isn't the right value.

Hi fellow forum-goers, I'm trying to add a general-purpose CAN to UART function to an LPC2129 setup. CAN1 works at 250 and 500kbps, so I modified my code to add CAN2 but am experiencing difficulty. I'm hoping one of you gurus is willing to look over my configuration. CAN2 is supposed to be "scalable" to any of several baud rates, but I am testing on 33.3kbps on a SINGLE WIRE networ

Hi, I've recently inherited a project running an LPC2129 and FreeRTOS 6.1.1, and I've not got much background with this type of chip. I'm trying to enter ISP mode from user code, using AN10356 and the help of one website which suggested I use a watchdog timer to ensure I can exit after the code upgrade has been performed. My code, unfortunately, does not seem to enter bootloader mode. If ...

I am using LPC2129 CAN QuickStart Board and trying to get UART work. But I found the chip on the board is LPC2194/01, not LPC2129. And I did some research on the LPC2194/01 baudrate setting up for the rev 01 chip. Based on the baudrate calculation in the LPC2194 user manual, I set up the UART0 register as following: PCLK is 12,000,000 HZ Expected bitrate is 38400 U0LCR = 0x83; U0D...

I guess a tcp/ip stack hasn\'t ever been ported on the keil mcb2100, particularly running on the philips lpc2129 processor. Badly need documentation and/or source for porting a tcp/ip stack, running on any OS... FreeRTOS, eCOS, whatever.... but over the serial port of the keil motherboard.

I am trying to understand how to manage IO with interrupts when using CrossWorks Tasking Library (CTL). I have a small program with 3 tasks. Two tasks just blink LEDs and the third outputs via UART0 using interrupts. I seem to not understand how to setup interrupts on the LPC2129, or maybe I am not understanding CTL and interrupt routines. Anyone have a good example program for CrossWorks ...

Hi all I measured the execution time of the code shown below using break point= s in the keil simulator and it was approximately 500 micro seconds.=20 But when I measured the execution time of the same code from the Philips = ARM board LPC2129 it was about 3000 micro seconds. Do you have any idea about the cause of this difference? =20=20=20 Note that I used the following adju...
