How To connect the Microcontroller with our computers??
My problem is that..
"I have created One Device using micro controller which reads the Temprature.Hence i want to send that reading to the Computer and Display using c++ programe on console." So How we can connect that contoller to the computer?????

I also created one application using c programming bioscom function but that application display garbege value....

You have to use UART of microcontroller to interface with PC. and for that you need MAX interface chip too.

there should be an USB port within your microcontroller to be able to connect it with your computer like the arduino. if not, you should have your own MCU programmer.

hi.please make a small circuit where it can connected to your USB or COM port(Db9)RS 232 connector,to make a connection between Microcontroller and PC.In 8051 or other controllers as it is so called the ISP configuration concepts as follows.

There's USART & UART both.
USART : Synchronous-Asynchronous (device requires data+clock)
UART : Only ASynchronous (device requires data only)

I connected that device to PC using RS-232 cable to COM port and hence the "bioscom.h" header file gives facility to get input from COM port so the c program get's that output but compiler displays garbege value...I want that Binary Value Which is generated by device display on consol..

It would be great if you post a detailed reply which explains your current hadrware settings and task you want to implement.

You should brush up your programming knowledge first. Compiler just compiles the program - it CANNOT display garbage value.
