    I need help again

    My friend, I want to put 15 more words in memory, but it does not fit, so I thought of adding an EEPROM because many people use this method and put a lot of other information and pictures in it.

    I need help again

    I know that, but I build my projects with microcontrollers available in my country, and they are only 3 types. The best of them is 16F877, but it is large in size and has many terminals, 40 terminals, and this does not suit my projects. PIC recommended to me the number of limbs from 18 to 20...

    I need help again

    I made a new project with the 16C73B microcontroller, but when adding the words, the random memory was not enough, so I added the EEPROM, but I had difficulty adding the words to the EEPROM 24C08B. And I use Micro C program. Thank you for all the help you give me // Lcd pinout settings sbit...

    I need urgent help

    The program that I created must have an IF function because I have several choices. If the first choice is not fulfilled, it moves to the second until the last choice. If it does not check the conditions of all the choices, it gives me an error message and the program works very well, but I just...

    I need urgent help

    I have designed a program for the microcontroller and it works well, and I only need to put a welcome message at the start of the operation, which disappears for 2 seconds forever, and does not appear until I restart the microcontroller, and the program after that completes its functions well...
