LPC2129 - reading/writing char array to flash [2 Articles]
Posted by lawzaz in LPC2000 on May 16 2013
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...

... Control a LED with the MSP430F2012 [7 Articles]
Posted by Scutariu in MSP430 on May 16 2013
I have a question. I am new to microcontroller programing but I need to do a simple thing. So I
bought a MSP430F2012 in order to light a LED. The only problem is that I want to light the LED
after I press a button for 5 seconds. If the button is pressed less then 5 seconds, the LED
should not start. So far I managed to get the LED lightening on button press. I do not know how
to monitor the input ... lpc1788 real time clock problem [3 Articles]
Posted by firmware111 in LPC2000 on May 16 2013
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... regarding ADC

Hi,I am working on F2812 processor for BLDC motor control.As part of thios ,I need to use the
ADC in the processor.In order to understand the working of the processor,I started with the
example codes for adc.But when the output is checked in the watch window, it is only showing 0
whatever be the input voltage(between 0-3V).Can anyone please let me know what the actual
problem is.I've given all the... OFF TOPIC: good blogging websites ? [2 Articles]
Posted by rombios in Comp.Arch.Embedded on May 14 2013
hey all.
I used to use livejournal to blog about various embedded projects I am
working on. But they have changed their interface and they dont allow one
to post attachments.
So my question is - what do you guys use for blogging? Any good websites
that allow paid for accounts and space to blog, post source files and
pictures of various projects one is working on?
Thanks
... What happened to RFID readers IC U2270B from Atmel? [3 Articles]
Posted by pozz in Comp.Arch.Embedded on May 14 2013
I have an old RFID reader that is based on U2270B chip from Atmel
(previously from TEMIC).
It seems any kind of info about this IC are disappeared on Atmel web
site. There are only documents and info about RFID transponders, but not
the readers.
Is Atmel producing this IC yet? Is there a new modern device to use for
RFID readers?
... LPC2458 SPI_MISO setup time? [3 Articles]
Posted by dherity in LPC2000 on May 14 2013
The LPC2458 Data Sheet gives a typical value of 11ns SPI_MISO setup time in Table 10 on page 52,
but not a minimum. Does anyone know the minimum setup time?
Without this information, a reliable SPI interface can't be designed.
FYI, the LPC178x data sheet states a minimum of 14.8ns for the corresponding interface.

... LPC2132FBD4 RS485 polling problem: random resets [15 Articles]
Posted by chad...@bigpond.com in LPC2000 on May 14 2013
I have an interesting issue with a product thats been in production for 7 years
that now uses an LPC2134FBD64/01 it was originally designed using an
LPC2132FBD64 before the /01 parts where released, but the LPC2134FBD64/01
device has been used for years without any issues.
The product is polled from a PC via an Aten RS232 to RS485 converter
and for years this setup worked fine with very f... New devices and workshops
