How to connect signal generator to Stm32?

Question

Electronics

Good afternoon, it is necessary to connect the signal generator to the Stm32f407, but the legs of the ADC (PA3, PA6)
And also remove the signal from the DAC (PA4)
There is a code, but I can’t figure out the connection diagram. Do I understand correctly that we are throwing the outputs of the generator to the ADC and the receiver to the DAC into a blunt one?
If it is possible to demonstrate the connection diagram, it will be very cool
. Thanks in advance)

Answer 1

in principle - the main thing is to coordinate the amplitudes of the signals.
if your generator produces a signal of a wider range than the ADC can eat, it will be bad.
You can adjust the levels with a resistive circuit or with operational amplifiers. specific circuitry depends on voltages and all that.
the output of the ADC is similar, the circuitry depends on the required signals at the output.
plus low-pass smoothing, etc.
