Tool/software: Code Composer Studio

Hello,

I am interfacing 16x2 LCD (JHD162A) with TM4C123GH6PM. with 4 bit mode 

I am using code compose studio and I have lcd.c and Lcd.h, main.c files., while building I am not getting any errors.

I am getting some issues, Issues are the following :

Lcd shows black boxes blinking when I debug the code.

hardware connections are right because I have checked Energia code on the board, Energia code working properly displaying characters on LCD.

while checking with code composer studio I am getting black boxes blinking on the LCD  screen, when I checked the reason then on the internet I am showing that LCD is not initialized properly.

how to solve this issue? 

thanks and regards 

Deoyani

    Your issue is specific to the JHD162A LCD controller. Unfortunately I cannot help you with that part. Please contact the manufacturer of the LCD controller for more information on how to do the initialization. If you have any future questions on operation of the TM4C123 device, please create a new post.
