Help with ADC &16F628A

[peu]

You might look at the manual for the POT command. This is one option for measuring an analog signal without an ADC module. Another option is to use an external ADC or better yet, use a PIC with an ADC module on it. the 628 only has a comparator module.

ok, I can use 18F6220, so this is the new code:

adcon0=1
lectura var byte
trisa=%00000111


lectura=0
mainloop:

Adcin 0, lectura
serout porta.3,6,[#lectura,"."]
Adcin 1, lectura
serout porta.3,6,[#lectura,"."]
Adcin 2, lectura
serout porta.3,6,[#lectura,"."]

serout porta.3,6,[10,13]
Goto mainloop
End


Im trying to read 3 potentiometers on ra0/1/2

I use serouts to know if I read something

[edit] this code is working I missed the # in the serout

now I want to use the read value to set HPWM

so I added this

DEFINE OSC 4
adcon0=1
Rval var byte
Gval var byte
Bval var byte
trisa=%00000111

mainloop:

Adcin 0, Rval
serout porta.3,2,[#Rval,"."]
Adcin 1, Gval
serout porta.3,2,[#Gval,"."]
Adcin 2, Bval
serout porta.3,2,[#Bval,"."]

serout porta.3,2,[10,13]

hpwm 3,Rval,300
hpwm 4,Gval,300
hpwm 5,Bval,300

Goto mainloop
End


no luck again
