Thanks a lot for your reply. There seems to be a lot of hex files. I would like to know if the circuit diagram still stands for all versions of the programmer software.
Thanks all. I have solved the problem. I changed the USB to serial converter i was using. Seems like the previous one was faulty. The new issue now is that if power goes off from the mcu circuit temporarily, the system brings out a blue screen and then restarts.
Can i use any 8051 micro controller for the interfacing(ie C or S series) or is any one prefferable. I also heard about a program hyperterminal. I would like if am given tips to carry this out. I also dont know if it is possible using a USB to serial converter.
Thanks so much. The tutorial explained sending ascii. Another problem is that the serial communication uses the timer register. I also intend using that register for my application. Let me explain what i want to do exactly. The micro controller timers are configured as event counters. This...
hi everyone. i have not interface a micro controller to a pc before. i would like to send three set of data from some the micro controller to a computer so that it can be displayed on the screen of a pc. I have heard of parallel and serial communication but i dont know where to start from. A...
is there a way to sequence the conversion operation from the read time to the digital output of the adc804 with something like an astable timer and counter such that it keeps on converting the analog input continually.
In your circuit diagram, you used two not gates, any reasons for this as the output of the second not gate will be the same as the output from the micro controller. Would it be possible to an npn transistor like 2n2222 in place of the bc557. if so i would appreciate a circuit diagram for that as...
hi everyone
i intend multiplexing two 7 common anode segment displays with a port of a micro controller by making 7 pins common to both of them and then the last one for the multiplexing. i dont know if there is a transistor that can switch as fast as a micro controller . some one suggested to...
