Hi forum,
i want to make an 'Ambilight'-clone based on a RGB-PWM-controller. Therefore i need the 0,7V-R,G,B-signals present on the SCART-link to be converted into 3 signals that are going from 0-5V for the controller's A/Ds. my idea: amplifying the R,G,B-signals with an opamp, then rectifying and smoothing with some r/c combination ->A/D.
The controller part is working fine, but now i'm stuck with the opamp-part where i have barely any knowledge :-(
Can someone help me?
best regards
joachim
