I know you guys are going the right way but i still have doubts asto what i should do. As stefan gave me the code, i used it ditto as it was given, but i can read only 80, 80, 80 in all the registers.

I will ask one more thing. as stefan pointed ourt that i have 15 pulses and i too have checked that i have 15 pulses instead of the 16 shown in the datasheet. BUT, in the datasheet, on page 8 in the last two lines, it is written that "The first data bit to be transmitted at the first falling edge after the last last bit of command is written". So this would mean that the adress will be transmitted on the first 8 low to high transformations and then we will recieve the data from the HT1380 in the ery next 8 high to low pulses.

Now in the picture that i have attached, the first is what my old code looks like and the second picture is what my wave will look like if i use stefan's function.

This is what's confusing me.....not that my loop is working ...it's still not.....

pleasee give me your email so that i can send the IMAGE showing both the waveforms....
