Now you can burn microcontrollers in your home with less cost of making AT89S51 series microcontroller burning IC kit. AT89Sxx series IC’s have inbuilt ISP (In System Programming) module so we can burning microcontroller easily. Here is the simple board circuit for making of AT89Sxx series kit for burning hex file into on-chip. Continue Reading…

Serial communication is basically the transmission or reception of data one bit at a time. Today’s computers generally address data in bytes or some multiple thereof.  A bit is basically either a logical 1 or zero.  Every character on this page is actually expressed internally as one byte.  The serial port is used to convert each byte to a stream of ones and zeros as well as to convert streams of ones and zeroes to bytes.  The serial port contains an electronic chip called a Universal Asynchronous Receiver/Transmitter (UART) that actually does the conversion.
