I'm looking for compile ucos-ii RTOS port to the Philips LPC2129 with the GNU Compiler. The code available on www.micrium.com site is, instead, intended to be used with the IAR Compiler. First of all, I need to translate the assembly code for IAR Compiler to the GNU Compiler syntax (GAS, if I am not wrong), and I'm searching for a IAR Assembly User Guide but without success. Am I not able or...

There's nothing particularly complex about time-triggered (TT) systems. What it means in practice is that you are creating systems using a single interrupt. This interrupt is u

Hi, I've adopted some old code and I'll be the first to admit I have no idea what I'm doing. I'm working with LPC2129-based hardware running FreeRTOS 6.1. My code executed until I made a few small changes (defining and printing an array plus some basic mathematical operations). Now, when I read CAN values, "if" statements based on these values never trigger properly (almost as if the values cha...

Hi, For my final year university project I'm looking at using an ARM microcontroller. I'm leaning towards the Philips LPC2136/2138 at the moment. While I've used PICs and AVRs I don't have any experience designing in more advanced uCs like these. As I'm on a budget I'll stick with the GNU tools and make my own development board. Are there any tricks or tips when using WinARM with this ch...

I'm just getting started with ARM. I use protoboards that host an LPC2138 ARM-7. My toolchain is Crossworks / J-link, I've set up a project with a demo test file that's supplied with the protoboard, a trivial LED flasher in C. It's the only file in the project, and as a supplied demo it will be error-free. The build gives the following errors: Source object ARM flash Debug/crt0 has EABI ve...

I am using a capture pin in combination with a timer of the LPC2138 controller. Each time a rising/falling edge is detected the running timer value is captured and stored in a CAP register. I am using this method to measure timing between the edges and calculate the frequency of the signal (squarewave). Each time I enter my interrupt service routine I reset the timer (to start a new mea...
