Hello Everyone, I am working on a project which involves detecting the SDCARD attached to the SD/MMC interface on a custom LPC2368 based board. I have the LPC23xx MSC USB Bulk Only files from the NXP website. I tried out their code by generatinf and flashing the hex file and was successful in implementing it. Windows detected the device and I could see a Readme.txt file too. The size of the ...

Hi all, I'm having a problem using EFSL MCI library on LPC2378 using IAR Workbench. At a first moment, my aplication crashed when I use the malloc() function for allocate memory for my variables (pointers). It works well for a small time and after it crashed, every on a diferent call of malloc(). Well, initially I solve (or not) the problem using vectors on place of pointers (temporaril...

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 ...

Hi I have a system in which I have an external interrupt which wakes the system transmits UART data and the system sleeps again on LPC1114 (302). When I put this system in deep sleep mode it consumes 7mA of current. I do not understand why this consumption is so high ??? There are 2 more sensors on the board with it which consume around 10uA combined current. There is no other IC on the ...

I am trying to communicate with a custom protocol encrypted in AES 256 on the LPC1768 and the other end using a C# DotNet server. I am using the NXP AN11241_1 example code. On the PC side I use the C# code below. When I encrypt a buffer with a single 16 byte block, both sides encrypt/decrypt the same way and all works. When I fill a 48 byte buffer with data 0 through 47 and encrypt the buffer on ...


Keil ARM ULink2 LPC2400.c Startup Disassembly Errors

Using ARM uVision4 4.71.00 set for ARM mode, and the LPC2400.s startup file with a ULINK2 configured in B0 boot mode, I can not get the start up code to either single step or run. There appears to be an error in the disassembly and the actual execution of the code when using the ULINK2 and actual target. This error does not occur when using the simulator. When debugging with the simulator, the...

i am trying to use LPC2138 to control LTC1451 (DAC) by SPI protocol. I use Keil MDK-ARM uvision4. LTC1451: 12 bit, CPHA=0, CPOL=0; When CS is low the CLK signal is enable, so the data can be locked in. When CS is pulled high, data is loaded from the shift register into the DAC register. Load MSB first. My code is as the following. However, when I simulated with Proteus, it is not as the valu...

Hello, just received a brand new LPC-Link 2. Does someone know where to get a schematic of the LPC-Link 2? There is a LPC4370 on this board. I have not found much info about it in the Internet. According to numbering i would say, it is a flash-less part. Is this correct? What other things are there/not there compared to other LPC43xx parts? Best regards, Martin ----------------...
