I have a working circuit that I would like to integrate an LCD screen to display some values on, but have never worked with displaying values obtained from the circuit before.
The circuit controls is for a dual pulse welder (like you would see in a battery tab welder). The pulse lengths are very small, but need to be variable for welding different materials, as well as the voltage.
I will be using this LCD screen: NHD‐0216SZ‐NSW‐BBW‐33V3

5x8 dots
16x2 char
integrated driver: ST7066U
I want to display supply voltage (PS), available voltage (cap), pulse 1 time, pulse delay time and pulse 2 time. The pulse times are derived from 3 555 timers.
display will read like this:
-12.3V--12.3V-
-123s-123s-123s-
I would like to stay away from using anything that requires programming, I am building this project with the intention of it being "bare bones" (not smart), but need to be able to view the variables.
I also do not yet know how I will be measuring the values (volt, time) that I need to display, was going to work backwards from what the LCD needed.
any help is appreciated
let me know if I left any information out
