first identify two micro controller clock rate ,then calculate one instruction set how many time take for execute & calculate difference two micro controller execution time then adjust the program .
Here ps2 keybord interface with microcontroller,when ps2 keybord get the signal ,before key pressed sda line low for microsecond .I want to know what is the behavior of ps2 keybord before key pressed & what send to the microcontroller.In this program at89s52 microcontroller & 6-pin ps2 conecator...
when keybord send data to the microcontroller then clock signal generate ,my question is which are generate the clock signal ,if keybord generate the clock signal ,what is the first bit of clock bit high or low. In this program use the at89s52 microcontroller , 6-pin ps connecator.
my program shows the out put in i2c simulator but when hard ware test same program not give the out put.
8051 microcontroller ,assembly language ,at24co4 eeprom used in this program.
