Experience report: Using Modems für GSM/GPRS M2M Solutions [5 Articles]
Posted by Ruediger in Comp.Arch.Embedded on Apr 10 2013
Hi
I'd like to share some of our experiences implementing a
SMTP-Application using a serial modem.
Please see my other Threads in http://www.modem-gsm.de/forum for
detailed descriptions of our problems with the Telit modem.
We startet with the Telit Modem PCS-Version. After some time we had
major problems with the internal timing in the modem. Some at-Commands
must be handled very... 
Looking for small demo board for CC430F6147 [4 Articles]
Posted by lslonim2 in MSP430 on Apr 10 2013
Hi. I have a friend who is looking for a small demo board for the CC430F6147. He's looking for a
minimal system, just the basic parts to get it to run, with a PCB antenna and a few points to
connect to a SPI peripheral.
He's doing a feasibility trial for a product and is hoping to avoid the fussy RF layout
required, and the expensive assembly of the 0201 sized passives. The demo board from TI i... power consumption [2 Articles]
Posted by Pushpa Padmanaban in MSP430 on Apr 10 2013
I have multiple C programs each doing the same piece of functionality. I
want to evaluate/calculate which of these has a lower power consumption( on
ARM) Is there some tool(simulator) with which I can simulate and get the
number of power consumed and compare the same for each of the programs on
desktop?
Based on this I will decide which of these apps I will finally put on the
ARM.

Posted by Pushpa Padmanaban in MSP430 on Apr 9 2013
hi, i want to know
1.why msp430 is ultra low power?
2. how it differs from other processor while executing the code ?
3. will the power consumption be different for different codes(based on
appln)?
i want to do power measurement analysis in msp430 (instructions,registers
consuming power)
4. is there any book for this power analysis?
5.any formulas?
... Low cost mains power supply [12 Articles]
Posted by Nomen Nescio in Comp.Arch.Embedded on Apr 9 2013
In most DIY stores you can find these cheap Chinese digital timers to
turn you lamps or appliances on at specified time. The thing I'm
wondering is, how do they power the digital circuitry from
110VAC in a device costing only $5-$10? Are they using a transformer or
are they directly powering the digital circuitry from the AC voltage?
... LPC812 available!
Posted by Leon Heller in LPC2000 on Apr 9 2013
The LPC812M101FD20 (SOP20) is available from Digi-Key:

2M101FD20%20&x=0&y=0&cur=USD
Farnell is awaiting delivery. I'll order some from them when they arrive
as shipping will be free.
I'll design a PCB for them.

... LPC2129 (SW)-CANBus Error troubleshooting: RX Passive Error, REC = 128 [11 Articles]
Posted by lawzaz in LPC2000 on Apr 8 2013
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 network. I am us... LPC810 update [2 Articles]
Posted by Leon Heller in LPC2000 on Apr 8 2013
I've redesigned my little prototyping PCB for the DIP8 LPC810, adding a
jumper to enable bootloading and a 3x1 connector for Flash Magic
downloading (TxD, RxD and Gnd). The Gerbers have been sent off to ITead.
If anyone wants one of the old PCBs, please send me an email with your
address. The LPC810 doesn't seem to be available for sale, but you might
be able to get some samples out of ... IAR Error [6 Articles]

Hello Everyone,
I am seeing this error now with version 5.51.6 of the IAR EW-430 Compiler:

-------------------... Wrapping function calls using Diab compiler
Posted by nithi89 in Comp.Arch.Embedded on Apr 8 2013
Hi I am new to wind river compiler, I am trying to do robustness testing
using binary wrapping method, I know that gcc has a --wrap option for
wrapping function calls, I would like to do a similar wrapping using Wind
River Diab compiler, any ideas how to do this?
