thanks for the reply,,
actually I built the simple hardware kit using the AT89C2051, Max232 , rs232 and other necessary connection.Now my problems are
1.How to download a simple program of led blinking on to the chip from pc using keil software,, please send the detailed procedure.
2.some say that rs232 is not compatible to my system though i have D9 connector in my system, Is there any software which can be used to make it compatible.
3.whether RS232 connected to the system provide power supply to both the Max232 and AT89C2051 or we need to provide separate supply to controller
please help me in this regard
