Hi Ligo, I really enjoy your projects and how you explain the workings of it !!!
I’m new to C programming and is still busy getting the grips of it. I used to program in assembly but knew
some or other time I will have to learn this language.Thank you once again for making the learning so easy.
Thanks
Jonathan

In reply to Ilozulu Chidiuso. Hello, Who told to use 49 ? 63 is the correct value.

Dear Ligo, i tried to display 8 custom characters using a 20 x 4 lcd but the 7th and 8th custom character didn’t appear the way they were supposed to , so i took another look at this tutorial and used ” i <= 63 " in the for loop like you used and it worked perfectly. Please could explain how the " i <=63 " affects the display.THANK YOU. PS i used " i <= 49" in the first code.

Dear Ligo
Could you please explain more about function Lcd_cmd();.I don’t understand how to set adress CGRAM.
Why we set Lcd_cmd(0x04) and Lcd_cmd(0x00);.

Thank you
