I have appnote 11008 open right now and this seems like overkill for what I want (and I'm confused as to how I would extend for char arrays). I have a board that reads a configuration file from an SD memory card. Sometimes, that card is unreadable and a value is needed regardless. The boards are tuned for different devices, so a single default will not work. Since I have tons of flash memory...

Hi Guys, We have a product that uses the real time clock of the lpc1788. When the RTC is enabled it normally starts counting seconds then minutes, hours and so on. But recently we got several lpc1788's that count all of those at once. So the seconds, minutes, hours, days, months and years are increment by 1 each second. A few days ago we got about 20 PCB's and 14 are working ok, but 6 of...

Hi Has anybody used Power Down mode in LPC11A14. Apparently it only has a Sleep Mode and to use the power down mode one needs to shut down the PLL. I have set up external interrupts and then I shut down the PLL. I have programmed in a way that the PLL turns on in the ISR.However this does not happen and once it shuts down it does not start again. Has anyone worked on this ? Can someone...

trying to come to terms with my usb firmware. enumeration errors I am currently seeing take place just after the HOST pc sends me the SET ADDRESS command. I set the value but HOST pc flags an error. The exchange (dumped from the serial port looks like this) as seen on my lpc2378 usb device - (my firmware code) is: ---host initiated reset--- 80 06 00 01 00 00 40 00 ---host initiated reset-...

Hello, I've got problems programming LPC1112 with SWD : - I made a first board 2 month ago who's working perfectly with my J-Link ultra from Keil. - Now I receive 2 new PCB and I test them with 2 new LPC1112FHN33 (different batch number than first one). I can't program these boards. One time it write "erase failed" and next time "erase done" then "Flash timout" I connect SWDIO and...

I can't quite believe i'm having this problem! i'm a professional software/hardware developer but not in the GCC/Arm world. I'm a real newbie in GCC but have C experience on other platforms. I'm so stuck...but I suspect it must be something very simple. I have a very basic GCC program that can't access any of the standard functions. I'm targeting a philips LPC2129 ARM7 processor.

Hi All - I have a program running on LPC2148. There is a requirement to store some of the user data onto Flash. I'm using the IAP commands to do the same. Whenever I write to flash location, it seems to work only if I first Erase the sector, prepare the sector and then write whereas the LPC2148 User Manual seems to indicate that only preparing the sector is sufficient (erase is not requi...

Hi fellow forum-goers, I'm trying to add a general-purpose CAN to UART function to an LPC2129 setup. CAN1 works at 250 and 500kbps, so I modified my code to add CAN2 but am experiencing difficulty. I'm hoping one of you gurus is willing to look over my configuration. CAN2 is supposed to be "scalable" to any of several baud rates, but I am testing on 33.3kbps on a SINGLE WIRE networ
