How to read analog value (Potentiometer value) and display it on 16x2 LCD with TM4C123G ?

Hello Islam

The forum is a place to discuss issues and not a free code repository. Having said, if you are looking for guidance, then let's discuss

1. You can read the Potentiometer resistance value indirectly, by connecting a fixed voltage across the pot and, then reading the voltage of the wiper terminal. Knowing the range of the pot, the min, max and wiper voltage, the resistance can be derived.
2. There are numerous panels. Which panel are you referring to?

May I agree w/vendor's Amit - poster needs to narrow focus - demonstrate (some) time/effort investment in his/her project.   (none currently reveals)

As to the Lcd panel - may I note that 99% of such "Character Lcds" employ the "Grandfather of all Char. Lcd Controllers" (HD44780) or one of the many clones!   Only exceptions are the very newest character modules - which may have moved to I2C or an "SPI-like" interface - reducing the GPIO demands upon the MCU.

HD44780 style LCDs require a parallel interface - either 4 or 8 bits - along w/2 control signals.   (8 bit is highly recommended - even experts are initially challenged by the 4 bit initialization & extended timing)   A contrast pot is usually required - incorrect voltage level renders the Lcd unviewable...

One further suggestion - poster presents a highly specific "project need" (homework, anyone) and his, "newness w/LPad" - yet (any) reported familiarity w/the MCU/peripherals & coding sits silent.    One crawls before walking - and reads the fine manuals (both MCU & LCD) & runs many code examples - prior to attempting homework projects!

Hi Amit,
I just need some guidelines concerning with port initialization , the methodology and equations to calculate the analog value, and not the ready-made code..
I'm using KL SN 102 94v-0 lcd ..

Thank you!
