Hi,
I have a PIC16F877 that get PCM data from an EEPROM 24fc256 and put it on the PORT D. this phase is going nice.
but after the data from PORT D is converted with a DAC0808 and amplified before read by the speaker. my problem that the speaker didn't work as i want: no audio only noise like "knocking on a board".
Please can someone light me the way for the solution.
