I am observing a really strange problem.
I have hooked up SD CARD and DAC to lpc1343 ( the dac is drived with software SPI). But i noticed that when the spi works introduces noise to the dac. Any idea how to remove that interference? (both hooked up on the 3,3V on the lpcxpresso board). I did decoupling near the card and the DAC but didn't have effect.
Thanks in advance.
