I'm having some difficulty with my transmit interrupt on an LPC2106. I'm using winarm. My rx interrupt works perfect, when new data is present I quickly add it to a buffer and take out the bytes in the buffer in my main loop. My tx buffer however has a bug. When programming for avr's I had two types of interrupts tx buffer empty(which I used) and tx complete and it worked perfectly. ...

I'm trying to get the FreeRTOS lpc2106 demo application compiled in Eclipse. I didn't change much to the demo files. Since I am trying to get it to work on an lpc2292, the memory sizes were changed.

Hi, I am newbie to this field. I am using LPC2106 microcontroller and KEIL microvision to develop the application. Is there any CRC calculation is implemented automatically? How I can calculate the CRC for the different Hex output file. Any one knows please brief about it. Thanks & regards, S.Saravanakumar

Dear all, I've just finish to work on some lpc2106 new design. Now I like to discuss or know some working solution (of course we like to know the better way to do it then learn the concepts) to do a in field microcontroller firmware upgrade. For one of this design we need to connect remotely trough a industrial modem connection and we need to perform the microcontroller firmware upd...

I have been trying to follow James Lynch's tutorial on the lpc2106. I have modified the linker script for my lpc2292. I am having trouble getting the Eclipse debugger to work properly. I don't get an actual error in the console window, I just get a dialog box saying "Error during launch." What types of things should I look for to help me troubleshoot what is wrong?

Hello, I have a LPC2106 code using the UCOS II but compiled and build with the CARM compiler. I am trying to port the code to compile on the RVDK. The UCOS II for the CARM compiler has __arm instructions which doesn't seem to be compatible with the RVDK and also the original author has deleted the headings so I don't know the version of UCOS. To start of the port to RVDK, I copy some o...

Hello, I'm currently student in placement (and french by the way, sorry if i do some mistakes on my posts ^^'). I have to connect several sensors to the kickstartboard (lpc2106) and monitor them on a terminal (for the moment). The problem is I'm a real newbie when talking about ARM, I only know PIC uC, and it's really different as you know... I'm not able to send something on spi AND...

Hi, These two registers (EXTMODE, EXTPOLAR) are listed in the newer user manual of LPC2106 ( UM10275, 4 June, 2008 version), but are not listed in the older user manual, and their definitions are also absent in IAR Embedded Workbench 5.11. However, the newer user manual doesn't list these registers as specific to /01 revision. As I am currently using the older LPC2106 (not the /01 revision) can I...

Hello, I had question related to program startup. I am using LPC2106, when I press reset, Primary bootloader get called. Then my secondary bootloader comes in picture. It will download the hex file from UART and burn the flash. Now I need to call new application. Whether I jump to main function of new downloaded code or to cstartup function. Thanks

Hi, i am working with a Development Board based on a LPC2114. We have made the port for FreeRTOS using the instructions available in FreeRTOS's web page, modifying the Demo for LPC2106 (because we use GCC compiler) and comparing with the Demo for LPC2129 (because there are only very little differences with this micro). The Demo seemed to worked just fine, but the problem comes when we use th...

Hello, I am trying to write a block of 512 bytes of data to flash in LPC2106. For some reason it only writes a first couple of bytes. After the write operation, it does return FLASH_CMD_SUCCESS. Anyone have any idea why would it do that. Here's the my flash write function: Uint32 FlashDriver_write_configuration(FlashDriver * this) { Uint8 memmap; Uint32 cpsr; cpsr = d...

Iv been working on this problem for the last three days with no avail. Basically around 80% of the time the first strings/chars sent by the MCU are garbled. It is only after the MCU receives something that everything works fine i.e. I can send or receive with loosing any data. My code is standard, I don't think theres any problems with it,debugs fine in kei
