hi all,
i need to design a power supply for sourcing high current. the supply should be current controllable through a matrix keyboard interfaced to the PIC i.e. the supply should be capable of sourcing any current entered through the keyboard. An LCD interfaced to PIC should display the voltage, current & other options.

any design ideas & books for reference would be very helpful.

thanx in advance.

Lithium.

Yes, this all looks Ok. But you must be aware that at lower 10% of meassurement area you will get nonlinearity of meassured results.
