I am using lpc2148.i am storing wav file data into an buffer. i am placing these data bits in DAC register after an interval but i could not listen any thing. if sampling frequency of wav file is 8k Hz then what must be interval in between placing bits in DAC register please help me.
If sampling frequency is 8kHz, then that is obviously also the speed needed to have the DAC switch to the next sample. 8kHz = 125us/sample.
