Hey this is my first post on EG, hope to be apart of the community for a long time, moving forward. Im trying to build a simple circut using an AT89C51 with a DS1307 interfaced with a 16×2 LCD. I know there are numerous projects other and thats the reason why im repeating it, to learn. The problem is now when i flash my code to the uC and connect it into the circut the lcd just displays bars. I’ve tried with alot of different programs avaliable online. Due to my lack of experience i have no clue how to debug this issue. I’ve also tried a smiple program to check the LCD and thats not working to a simple Hello World program fails to display. I’ve attached a schematic of my breadboard circuit and a picture of the whole issue.
