Hi, I will connect my ADE7758(metering IC) to a Z8 Encore! MCU through SPI (4pins: SCK,MISO,MOSI,CS). My problem is, although the input and output voltage ratings of the two chips match(5-6Volts input and output), I feel that there should be some hardware in between, meaning, I should not DIRECTLY connect the SPI pins of the MCU to the pins of the other IC. Any help on this matter will be well app...

Hi, Why powerpc debug tools are so expensive? Does anybody know low-cost USB powerpc jtag/cop ? Amontec website mentions about USB version of Chameleon POD but no informayion for now. Macraigor cheapest usb hardware is $225 + they sell their flash programming software for $500. Any chance to find some open hardware-software combination? thanks

ML403 - Virtex4 - PPC405 - Xilinx EDK V10.1 Hi, I have a working PPC405 design to which I want to add the APU FPU IP (enough acronyms?). I have used the wizard to configure basically the same design, but with the FPU included - this is therefore the default wizard hardware design with no manual tinkering from me on either the hardware or software libraries. This now runs non floati...

Hi, Can anyone tell me where can I find a network device like those ADSL modem devices without a system installed? I want to install a customized freebsd system onto this device for my own use and school research. If purchase a off-the-shell modem product with the system installed, my end product will not be competitive. If I can get a hardware device only proudct without the cost of ...

Nowadays the poor embedded developer faces new challenges that go outside the limited world of C/C++ program on a resource constrained hardware. Now the hardware isn't so resource constrained (Raspberry and many other embedded Linux boards or SOM are just examples) on one side. And the device isn't isolated anymore, it is usually connected (directly or indirectly to Internet). The Th...

Hi, We would like to announce that the CyaSSL embedded SSL library now has support for hardware-based cryptography and random number generation offered by the STM32F2. Supported cryptographic algorithms include AES (CBC, CTR), DES (ECB, CBC), 3DES, MD5, and SHA1. For details, please see the original blog post, here: http://yassl.com/yaSSL/Blog/Entries/2012/12/27_STM32_and_CyaSS

Any one got any good reference for most common hardware topologies applied to robotics? Topologies i mean, how the sensors or actuators are connected to the main controller. As an example, if the sensors and actuators are connected directly to the embedded hardware (for microcontrollers) or expansion cards (for embedded PCs like a PC/104) it would be a very centralized topology. I am no...

Do you know of some open hardware that runs officialy openwrt? I'll try to explain my needs. I have to develop a board that runs Linux embedded for a VoIP application. I need two Ethernet ports, LAN with active POE (where to connect a VoIP phone) and WAN (maybe with passive POE, where to connect a router). So, the IP traffic could be routed to the external router connected to WAN or, ...

I hope to get your feedback of what you think of integrating IAR EWARM (probably the same for EWAVR) with the hardware development scene. All our hardware design tools have Tcl scripting support for batching. I think it would be great to have the IAR simulator communicate with our FPGA simulator ( in our case ModelSim ) . This way we can make nightly builds possible and make tests with ...

According to the meager description in the SPRUFL6E datasheet, the EMIFA of TMS 674x/OMAP supports hardware ECC for NAND flash pages up to 512 bytes. Would it be possible to use the hardware ECC facility for larger pages by restarting the ECC calculation at every 512 bytes of transfer? Or will I have to do everything in the software?

Hi, I plan to make a router application using a Coldfire, a Blackfin or an ARM7 running uCLinux. I can not find any information on the minimal Flash/Ram required to run uCLinux. My application will take about 256 kbytes Flash and 32ko RAM. Does anyone have experience on running uClinux on small configuration ? Will I have any problem if my hardware has 2Mbytes Flash and 256kbytes of RAM ?...

Hello, i have a self developed device (USB 2.0, full speed) which seem to make problems during connecting. WinXP tells me unknown device, VID and PID are both 0. I tried to monitor exchanged frames SnoopyPro seems to capture only frames when a valid VID/PID is available, not before... Because i have no access to a CATC or other hardware monitor, what posibilities are there to track do...

i'm a newbie in Embedded world. I need some clarification about the arm gdb debugging. 1. Is there any options to debug the board through serial port ? how? 2. All search results about the arm debugging are related with some kind of external hardware and JTAG why? 3. I found results about gdb stubs for some non arm architecture. is there any stub for arm without a external hardware or JTAG...

I'm working to improve a test program for the hardware I use to test some boards I make. These boards are tested using a test fixture controlled over an RS-232 port from the PC. So I don't need to lug hardware around with me I emulate the test fixture on the same PC I run the test program. I need comm port emulation software that will emulate a bridge between two serial ports to

Hello all, I am about to work on my first embedded x86 project. I have four years of embedded software experience. However, all of that experience has been with ARM, SH, or XScale based hardware. We are doing a custom x86 hardware platform, and my group is responsible for developing design verification test software as well final functional test software. To be perfectly clear, I'll share ...

Hi, I need to develop a embedded hardware (with a FPGA, example Xilinx(R) Spartan-3AN FPGA) capable of IDENTIFY what kind of USB web cam is plugged-in (example webcam manufacturer, speed, data transfer rate, etc.), the USB will work with USB 1.0 or USB 1.1 (not USB 2.0) so a USB 2.0 web cam will work at USB 1.1. Due this is a embedded design, no computer interaction is required (this means that th...
