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

Could anyone help me to run the IAP commands on KEIL MCB2100 (LPC2129)? I am working with the ARM RVDS tools (& RV ICE) and tried to run a small sample calling the IAP commands (program runs from iRAM). Most time I get a "memory access violation" several

I represent a new company called TTE Systems. In keeping with the spirit of the season, we have just launched a *free* software tool called "RapidiTTy Lite". RapidiTTy Lite is based around GCC ARM and Eclipse and targets LPC2xxx microcontrollers. The examples included with the tool target the LPC2129 microcontroller (and the Olimex LPC-P2129 board in particular). They can be adapte...

Hi, Can anyone tell me how to write an UART RX ISR in order to receive several kinds of packets with different length? The kernel is FreeRTOS. I have excerpted one piece of sample code snippet from one of the FreeRTOS demo port for LPC2129, as bellow. [code] __arm void vSerialISR(void){ signed char cChar; portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE; switch(U0IIR & serIN

Hi all I am working on single edge PWM generation on LPC 2129 .The summary o my work is as below 1)I am able to see PWM output on Pin 33(PWM 4).it is as per my clock settings.No problem still here. 2)In the PWM ISR,I am setting 2 flags and in the main loop of the code ,and based on these flag values I am dynamically changing PWM4 rate by changing PWMMR0 ;PWMMR4 PWMLER registers. 3)These above ...

I am attempting to use the freertos lpc2106_GCC loader files and boot.s file for the lpc2378 keil evaluation board to bring up a simple blinking led first. then the entire freertos demo. I only modified the loader file to what you see below. I left the boot.s file untouched. > From my other ports from lpc2106 -> lpc2129 and lpc2148. this is all I had to do. For some reason this is not

I'm new to ARM development. I'm using the Keil uVision3 IDE and the Keil MCP2100 Dev Board with LPC 2129. I need to know the values to set in order to make the CAN bus work at 500k. Below are the values for 125k and 250k as provided in the Keil demo example. I'm not sure for what tSEG and SJW these values were calculated. // Keil Demo Common CAN bit rates #define CANBitrate125k_12MHz...

Hi, I'm trying to add CAN support to some existing firmware that runs on a plug-an-arm (from newmicros.com). I'm having trouble getting anything CAN related to work. I have reduced my test code to some extremely minimal test code (adapted from this book: ): #include #define REG32 (volatile uint32_t*) #define GPIO

Transmission is done through push message function in which ...

How do you define a .text and .rodata for a c module in Crossworks? How do you add these sections to the flash_placement.xml file? I am trying to make a IAP boot loader code section that I can locate at the top of the LPC2129 flash range. I used : #pragma section text=".code_section" #pragma section data=".my_data" #pragma section bss=".uninit_data" I know how use to include ...

Hello, I need to disable the interrupt completely for a short while. I have found that the ARM7 can disable interrupts with the DI and EI asm. Theese does only work for me in the startup.s file (I made a test) and not as inline asm where I really need them. I have found some code that may work inline, but can someone tell me about their experienc

Hi, I'm trying to log data to an SD card on the LPC2129. I have a good SPI driver written, and I can read/write regular SDSC and MMC cards using the driver here: https://github.com/vsergeev/embedded-drivers/blob/master/sd.c This seems to follow SD spec (with the possible exception of querying voltage using CMD58 early), and works great for standard capacity cards. However, anything high c...

Dear Ladies and Gentlemen, I have to develop a very safe CAN Bus application that have to resume its work after a short circuit on the CAN Bus in real time. I have developed a CAN Bus Application with up to 40 CAN Bus Members on a Line, and it works very very well. All Controllers are Philips LPC2129. A few days ago, I simulated a short circuit on the CAN Bus lines with a duration of a

Hi All, I am now in the need for a real time kernel and interested in porting FreeRTOS to LPC2888, but until now still has not succeeded, but in the mean time I found out that a real time kernel (ARM-RTX) was included in my Keil MDK license, As the kernel bundled with the MDK does not come with the source code and all the examples are built for LPC2129, LPC2103 and LPC2138, is it possib...
