    ATMEL vs FREESCALE or another one?

    Sir you need to specify your intended application and which ARM architecture you plan to use. I use both Atmel (M3/M4F/Dual Core M4F) and Infineon (M4F) ARM MCU. Both are equally good. Personally I found Atmel has an edge with respect to communication peripherals (both quantity and simplicity to...

    Power Analyzer Design Problem

    I need to design a low cost power analyzer for my thesis work (solar inverter system) as one is not available and their is no plan to buy a new one. Power Analyzer will only be used as an instrument for measuring electrical signal of characteristics 230VAC; 0.5-10 Amps. current; Single Phase and...

    Convert voltage to current linearly without using opamp?

    If accuracy or stability is not a huge consideration then just connect a resistor in series. Looking at your values 10k resistance will work.

    current measuring question

    Probably. Kindly conform that you have completely isolated positive terminal of power supply from the circuit and only and and only one path exist from the positive terminal of your power supply to your circuit that must be your ammeter. Also make sure you have selected a proper display range in...

    24V Power Rail on CAN bus or RS-485

    Sir, I thank you for our suggestion. I had looked at this particular IC but was passed over as our vendor (Digikey) does not provide it. We have selected TLE6250GV33 provided by Infineon AG. The power was provided by dual output LDO as specified in application circuit for the IC. My only...

    What is the difference between posix ipc and system v ipc in linux?

    System V is used from Old version of Unix system operating system API. POSIX (Portable Operating System Interface Unix) is meant to be new portable implementation of API created after during Unix War. POSIX is supposed to be thread safe and is relatively advanced but still System V is used...

    24V Power Rail on CAN bus or RS-485

    We are building an automation system where by sensor will be separated form indicators/totalizator by few meters. We have decided to use CAN bus for communication between sensor and indicators. We are suppling 24V to the sensor module. I would like to know if it is possible to supply power over...

    CooCox/FreeRTOS Usage and Licensing

    We wish to develop commercial application. We am using Atmel SAM3N and SAM3S MCU with Atmel Studio 6. We plan to use RTOS in this project. We have shortlisted 2 candidates FreeRTOS and CooCox CoOS. My question is about their licensing. If I use them for commercial purpose what will I have to do...

    What is fundamental difference between x86, MIPS and ARM

    The major difference is how they do it (fetch instruction, decode, execute and store). In general in layman's terms x86 can directly perform operation on main memory while PPC and ARM require operand to be loaded in their local register before any operation can be performed on them. Length of...

    Udoo or Wandboard or Parallela?

    Sir I would suggest BeagleBoard-X-15. Its specs look very promising especially AM5728 processor. The board will come with 2 GB RAM, 4 GB flash, USB 3.0, 1 Gb Ethernet and the list continues but the real goody is AM5728 processor which contains Dual Core A-15 at 1.5GHz, Dual core ARM M-4 at...

    How many ways data can communicate between the processes in RTOS or any Linux OS?

    Sir please re-phrase your question. Inter-Process Communication(IPC) in Linux Kernel can take place as : Pipes of all types/kind Shared Memory (using semaphores) Message Queue Sockets File Based
