Matlab to generate sine wave of discrete signal coe files, transmission to FPGA board DAC module, reoccupy DAC module to the ADC module, at last, through the ADC module output to the screen, want to ask why the waveform amplitude is not obvious?

Two modules are set to 8 bits wide, coe file size distribution of the discrete signal between 0-255

CodePudding user response:

Detect the actual output, you can use the oscilloscope direct detection DAC side, or use the digital waveform logic analyzer to check the DAC

CodePudding user response:

Is not set before data bits wide, has now been solved, thank you!
