Is there a reference hardware design of how to connect some little speakers (e.g. 1W) to the PicoMOD7A (amplifier, resistors, capacitators, speaker)?
The cause of my question is that we have much noise on the speaker. We're using an audio amplifier and a little speaker. We can hear all the sound we're playing on the PicoMOD correctly. But we also hear much noise. This noise seems to depend on memory access. If I don't do anything on the memory bus the noise is very silent. If there's much traffic on the memory bus (also during the complete boot process) the noise can be very loud - it's as loud as playing a soundfile.
Thanks for any idea.
