i found on internet a lot of 8051 programmers , i need a simple programmer using serial port not parallel port
just using the MAX232 and the main micro controller i need to program only 89s52 or 89s51 not any C family .
also i found some programmers using another chip with internal firmware i don't need that also , so if any programmer using only MAX232 and main controller.
i found this circuit so if i did it , it will work or not ???
okay for this programmer how can i download the hex file on atmega8 , i need another programmer for it or just connect atmega8 to usb and download the firmware
I find s suitable Programmer using serial port for AT89Sxx
all i need is all of your opinion about this programmer if any one did it before without any problems
i think there is a missing ceramic capacitor on 89Sxx chip on crystal
so any suggestions
