    Hi, I feel KEIL compiler should be a good compiler for 8051 micro controllers. It offers a wide support to other micro's as well. An user friendly compiler which can be freely downloadable as well.

    Microcontroller hangs in a project which uses 89S52 to control synchronous motors

    how to solve hang problems with microcontroler The Problem could be with the current consumption acquired by the motor. Did u use a correct current driver? Check with that.

    need discription or abstract of any project based on 8051

    8051 Those names are the generic names of 8051 family. Try to purchase Mohammed Ali Mazidi and Janice Gillespie Mazidi and Kenneth J.Ayala. These two books help u a lot. U can independently program if u master those books.

    asm for microcontrollers Choosing C for programming is a better idea than choosing asm. But, try to know assembly. C is time consuming, easy to program, easy to debug and edit and u can use the same code for different controllers of 8051 family. So, go with C

    interfacing LM35 to 89c51 microcontroller.

    lm35 mounting Dear friend, connect the output of the LM35 to any ADC(0804,0806 etc.,). Interface the ADC with the microcontroller. U need to connect RD,WR,INTR,CS of ADC0804 to any port of mc. Give necessary control signals to get the digital o/p.

    Which language is more commonly used for programming 8051?

    8051 Go with C. It is user friendly, u can able to debug easily, correct ur errors easily, u can able to use a same pgm to task by editing a bit. I recommend C as the best language. It saves ur time a lot.
