Hello.
I'm making a variable power supply, and using a PIC microcontroller to monitor the voltage the current, and display into an LCD.
Is there a way to regulate both voltage and current with ONE LM317?
(regulate and also know that limit, ex : Imax = 1.2/Rx)
I've found some schematics going with this design down to zero volt, but first, it uses a center taped transformer, second it uses two LM317 regulators...
Anyone to help with some ideas?
