ADC multiplex with 4051

[rmteo]

Offcourse I forgot the brackets

I made one error in my explanation

the first mux is on AN0 the second one AN1
so in the middle of the for nextloop i need to switch to ADCIN 1

Your single loop for ADCin0 and 1 is not clear to me

Yes, I did leave out setting PORTC in my single loop example. If you are using AN0 and AN1, try this.

for i = 8 to 23
  PORTC = i
  if i < 16 then
    ADCIN 0, AD[i-8]
  else
    ADCIN 1, AD[i-8]
next i

You can also use a single analog input by tying the outputs (Z pin) of the muxes together to AN0 then the code is simplified to this. Insert appropriate delays in both cases.

for i = 8 to 23
  PORTC = i
  ADCIN 0, AD[i-8]
next i
