Please tell me why when loading an array of 16 numbers on the SPI interface in the range from 0 to 1000 at the DAC output signal non-uniformity of speed there. Who has experience in supporting chains and who faced such a case.
Hi! You have seen this pattern before. The picture presented by the output signal from the DAC. Speed SPI interface - 0.5 Mbps. On the horizontal axis of the waveform in one cell 50 microseconds, on the vertical axis 500 millivolts per division. The amplitude of the output signal of about 2.5 volts.
