    Is OOP suitable for embedded system ?

    I think that using C++ for compiled OOP characteristics may help in the development of the software, which always needs to be changed. If you do not use polimorphism, virtual functions and runtime binding you can make a project with an object oriented filosophy that will help you in the future...

    Which DSP evaluation board is good?

    DSP comparison for motor control You should see: -How many ADCs it has and the speed and bits of them -How many PWMs it has -What kind of motor you want to control and the method you want to implement -If the SDK that comes with the DSP covers your motor control technique -Fault inputs -How...

    I need Code example for DSP56f8XX without using SDK

    pilot, have you compared Motorola and TI DSPs? Because I have only worked with Motorola's and I think that its documentation is not so good, as well as I think that SDK is great. Just want to have some other's point of view.

    how much you would earn per hour in your country?

    Even worse Don't worry, in my country people who work in PCB design earn less than U$S 300.

    ISP programming of ST7, AT90 and AT89

    Code Vision You can try with the Freeware version of CodeVision AVR. The web page: https://www.hpinfotech.ro/ I do not know if you can download it from there..., so try. Then you can programm the unit with a home made parallel port programmer, using In System Programmer for Atmel.

    junior C coding question?

    That is correct with unions and structures. Pointers always have the same size (32 bits in Windows or less in embedded), so if this pointer points to a char you will send 4 bytes instead of 1, but if it points to a huge structure it will be 4 bytes long as well.

    Which DSP evaluation board is good?

    Motorla DSP Evaluation boards Hi mImoto I am working with Motorola DSP 56F805 at the University, so I do not know the exact price of the evaluation board. Here in Argentina you can find the EVM for U$S400 (I think). You have to know what kind of application it will work in, to buy the right...

    Atmel AT29C020 flash programming

    atmel at29c020 Hi all, I am working with AT29C020, and when I program the flash I wait in a loop for the flash to go out of programming mode. This algorithm goes right with ICs dated before 1998, but sometimes it fails with newer ICs. The problem is that the flash stays endlessly in programming...

    Embedded tcp/ip through PSTN

    Embedded tcp/ip I need to get information about bulding a tcp/ip net with embedded controllers through PSTN. I have the IP modem but I do not know how to do the data exchange protocol in it. Is there any standard solution? (better than simple FTP and SMTP) Thanks for information.
