Hi: I have a question with regards to the CAN_H and CAN_L pins of the LCP11C24. My understanding is that this microcontroller integrates a CAN transceiver, and these pins can be directly connected to the hardware layer of CAN bus. Looking at reference designs, one of them for the MCB1000-vers26 (which I believe is the latest available) shows on sheet 2 that the CAN_H/CAN_L are connected ...

Hi, I have a sensor sampling task which runs periodically with delay implemented using xTaskDelayUntil function. I have another UART read task. A delay value is send through UART and the currently running sensor sampling task is deleted and a new task with new delay is created. [using xTaskDelete and xTaskCreate]. However the task is not seemed to start again. I am passing the delay value as pa...

Hi Guys I have been working on LPC1114 using LPCXpresso on a Mavericks. I needed to create a same firmware thousand times with different embedded serial numbers and get the respective hex. Can someone help out with automating this process. I guess writing a shell script or something with change in the serial number through vi editor and building the project with saving the hex every time...

Hi to everyone, in the past 2 days I read several emails, too much in my opinion, revealing that too much engineers and students don't know so much about specific functions provided by Cortex-M microcontrollers with more care about those made by NXP. All NXP Cortex-M families of microcontrollers (with the exception of some MCU that have no flash memory inside) provide a data to distingui...

Hello, I am trying to program the flash of a LPC2387 via IAP. I use the code provided in the LPC2300 user manual. When I try to write a simple test pattern (0x00, 0x11, 0x00, 0x11...), after reading again I get corrupted data like 0x00, 0x01, 0x00, 0x10. So something is written, and you can recall the pattern, but the data is corrupted. Here is my write routine: iap_comm...

Hi, I am looking into low power LPC controllers but I cannot find any sheet or document that compares the power consumption in different modes. Can you suggest me with the best controller. It can be from any ARM architecture but would require atleast 256K of flash and 32K of RAM. Please help me with your suggestions. -- With Regards, Nishant Agrawal
