Non-text format for source code [65 Articles]
Posted by Vladimir Vassilevsky in Comp.Arch.Embedded on Feb 12 2013
For great many reasons, it would be convenient to have source code in some
rich format rather then plain ASC text. I could think of embedding
illustrations, links and data into file, custom coloring, individual styles,
comments, automatic macro expansion, presets and other features offered by
modern word processors. The idea seems obvious; so there should be a tool
for that already. That... 
large microprocessors? [42 Articles]
Posted by Paul Rubin in Comp.Arch.Embedded on Feb 12 2013
I notice that the ram capacity (ignore program flash for now, but it
tends to basically be proportionate) of microcontrollers seems to grow
fairly continuously (say in 2x jumps) from very small (a dozen or so
bytes in an 8 bitter, lots of MSP430's in the 128 to 1k byte range,
Cortex M0's with 4k, etc.), up to about 32k (Cortex M4). Above that
there are a few chips with 64k or 128k, that are ... CMSIS 3, has anyone use it for embedded example project [5 Articles]
Posted by Richard in LPC2000 on Feb 12 2013
I'm looking for source code or demo project file that make use of CMSIS 3 so I can see file
structure and how it organised within project folder.
I could not find suitable code and it seem no one bothered to use it since 2009(!), not even
CodeRed or Keil provides demo code with CMSIS V3 in it. Only V1.3 or V2.0.
I like to try out RTOS later on via CMSIS V3 or FreeRTOOS.
-------------------... Simultaneous use of SSP and SPI ports on LPC1700 [13 Articles]
Posted by ksdoubleshooter in LPC2000 on Feb 12 2013
I have a project using an LPC1768. This project has a requirement for 7 UART's, so I used three
UART's on the LPC1768 and added two SC16IS752's, which are dual UART's with selectable I2C or
SPI interface. I allocated SSP0 to one of the DUART's and SSP1 to the other. Each DUART has an
IRQ line and I ran these back to separate EINT pins. Running the DUART's on separate SSP ports
with separate interr... Non Standard Ethernet pass through connector [10 Articles]
Posted by steve in Comp.Arch.Embedded on Feb 11 2013
I have been asked by a customer if we can mount my networked product in a I=
P67 case.=20
It has three connectors, power, RS232(D connector) and Ethernet(RJ45 10/100=
) which need to pass through the case wall.
For the power and RS232 I am intending to use Souriau UTS Hi seal connector=
s (basically circular IP68 waterproof connectors)
I am wondering if the same connector could be used for t... Methods for Reading a Positive to Negative Range on an ADC [22 Articles]
Posted by Luther Blackwood in Comp.Arch.Embedded on Feb 10 2013
I have a sensor circuit that will output a voltage between -4 and +4 V. I need to pass this to
an ADC. What are some methods for reading this type of range on an ADC with only a positive
rail?
... NXP LPC1768/69 dev kits [2 Articles]
Posted by David Reaves in LPC2000 on Feb 10 2013
Hi folks!
I'm looking to play with a LPC1768/69 embedded device and have narrowed my selection to three
development kits: Code Red's "LPC1768 Development kit", the "UNO.NET/NANO1768" from Embeda.com,
and Embedded Artists' "LPCXpresso Kit EA-XPR-103" bundle containing the LPC1769 LPCXpresso Board
(EA-XPR-003) and the LPCXpresso Base Board (EA-XPR-021).
Disregarding cost for the moment, can an... What's the best MSP430 Development Enviroment? [65 Articles]
Posted by PFG in MSP430 on Feb 9 2013
Hello, I just received my LaunchPad board and of course I joined this group. I'm a veteran
software engineer with some hardware experience (physical circuit building, not just embedded or
firmware coding) but I'm new to MSP430 development. What's the best development environment?
Code Composer, IAR, MSPGCC, or Energia?
Here are my initial thoughts,
1. Code Composer has the needed device driv... Interfacing 3.3V SPI devices to a 5V MCU [13 Articles]
Posted by Simon Clubley in Comp.Arch.Embedded on Feb 8 2013
I'm about to do some work with interfacing 3.3V SPI based devices to
5V MCUs and unlike the devices I've been used to, these particular
3.3V SPI devices are _not_ 5V tolerant.
Interfacing the SPI output lines from the MCU to the SPI device is easy;
just use a level shifter on those lines.
In addition, you can just connect the MISO SPI device output line directly
into the MCU and it _shou... USB and UPnP Tutorials [2 Articles]
Posted by vppillai in Comp.Arch.Embedded on Feb 8 2013
Hi All,
As my first attempt to technical writing, I have put up 3 in-depth
tutorials (on USB 2.0, USB 3.0 and UPnP device architecture) at
http://embeddedinn.wordpress.com/tutorials/ . Please go through it and
provide your comments.
Cheers
