C preprocessor magic to put a define in a string [14 Articles]
Posted by Tim Wescott in Comp.Arch.Embedded on May 17 2012
Title says it all.
I'd like to be able to pass version numbers in as command-line defines,
then do some magic such that they can appear both in strings and in
numbers.
So, I call something like:
g++ -DMAJOR_VERSION=3 -DMINOR_VERSION=10 version.cpp
and in the code I do one thing in one place:
unsigned int major = MAJOR_VERSION;
unsigned int minor = MINOR_VERSION;
and in anoth... 
USB Host Controller for LPC2148 [3 Articles]
Posted by Marilou in LPC2000 on May 17 2012
Hello everyone!
Has anybody tried to interface LPC2148 with a USB Host Controller?
I have an existing project that is almost complete except for the USB Host Controller.
CH374 was the first option but there are not enough resources for the codes of this host chip.
If anybody has tried, I would appreciate advices and tips and sample source codes, if possible.
Thank you very much.
Regards,
... CAN <--> USB Adapter [11 Articles]
Posted by Soda Ant in Comp.Arch.Embedded on May 17 2012
Can anyone recommend a good CAN to USB adapter? I need to interface a
PC to an industrial control system that uses CAN.
I have two primary requirements: robust hardware (this will running in
a system 24/7), and a good C# API with good documentation and example
code (e.g. not a poor translation from Chinese).

... Any very low power SPI flash? [9 Articles]
Posted by Sink0 in Comp.Arch.Embedded on May 17 2012
Hi, i am developing a battery (CR2032) powered device that must log a few
sensors for a minimum of 3 months every minute but longer would be better.
The duty cycle is very low. In order to save the data i will be using an
SPI flash (16Mb). I was comparing at Atmel and SST (Microchip) and SST
seems to have the lowest current consumption device (max 15uA at standby)
but it is still a bit high compar... Pronouncing numbers [13 Articles]
Posted by Don Y in Comp.Arch.Embedded on May 16 2012
Hi,
I'm trying to settle on a pronunciation algorithm for
numeric strings (e.g., "1234567.89") for my *backup*
speech synthesizer (i.e., the synthesizer that MUST WORK
regardless of what else might *not* be working -- think
of this as the mechanism by which panic() messages are
emitted).
The backup synthesizer is more severely resource constrained.
OTOH, it also doesn't need to be as c... Re: Alternative sources for MSP430 CPUs ? [13 Articles]

Yes, this is correct.
Also:
PIC processors are only from Microchip.
AVR processors are only from Atmel.
... Is there a difference between a rabbit webserver & REST-base server.
Posted by Ty in Rabbit-Semi on May 16 2012
Hi Guys,
I have a web-server on my rabbit board but I also need a REST-based server on it. Is it possible? If so, how easy is it to implement a REST-based server to RESPONSE to HTTP REQUEST? Is there any examples out there. I would really appreciate any help. Thanks again.

... Reset value for IOCON bit7 in LPC13xx, 11xx [8 Articles]
Posted by Alexan_e in LPC2000 on May 16 2012
My question is related to a previous answer I have received from NXP
support about the consequence of setting bit7 of the IOCON register to 0
in LPC13xx, LPC11xx.
-----------------
NXP reply : Yes, take care with the IOCON registers (this has to do with
possible analog or digital behavior of IO pins.
------------------------
Bit7 in the IOCON register sets the operation of the pin to... ARM Cortex M3 newbie questions [27 Articles]
Posted by Boo in Comp.Arch.Embedded on May 16 2012
Hi,
I'm working on a project which is currently planned to use an ARM Cortex M3 from
ST (device is from the STM32L151xC series). I've never used the Cortex chips
before and my ARM experience is quite limited too, is anyone here prepared to
give me the executive precis of the state of the compiler/debugger situation for
these chips ?
If I'd been asked the same question 10 years ago a...
