Need help with voltmeter ammeter for PSU
Hi everyone, I am new to this board and very new to micro controllers. I have searched for weeks trying to find a design suitable and so far nothing fits my needs.
I am building a power supply 0-30V 0-3A
I would like to have a LCD volt and ammeter to monitor its output.
This is the design I am starting with
The problem with this design and most all the others I can find is it only displays one decimal place.
I would like for it to have a resolution of 0.05mV and 0.05mA and display at least 2 or 3 decimal places.
I've seen this requested on many sites, only for most to say it is very difficult floating point math, but it never got truly addressed or answered.
Any help you can provide would be greatly appreciated.
