Followed the video however my LCD on proteus isn't displaying the text. Any ideas?

[@SMtrainingacademy]

Can u share the code

[@aliabu2499]

In my practical circuit, it only display the boxes like output instead of my desire words. Could you help. Thanks

[@SMtrainingacademy]

Maybe some hardware issues did you checked it properly

[@spykespark8477]

Thank you very much for your time. However, I've tried to follow ur steps interfacing HD44780 on PIC18F25K22 nothing was displayed is there any specifics or exceptional if am using a different PIC apart from PIC16F877A?

[@SMtrainingacademy]

No mostly the code will vary only based on the registers in the microcontroller except that nothing will change @Spyke Spark

[@leekhaiming7690]

Thank you so much, may i know for the line 71, how to know write on 2nd line is C and write at 1st line is 8 which is on line 70?

[@SMtrainingacademy]

Hello Lee, These are commands of LCD where the address of first line starts from 0x80 and ends at 0x8F & 2nd line starts from 0xC0 and ends at 0xCF they are predefined and we cannot change it , Please also take sometime to visit our website: www.smtrainingacademy.com/ You may like other courses also

@@SMtrainingacademy thanks about it

[@VenkateshB23064]

while i am initializing the TRISB or PORTB i am getting a warning in side of the code saying that "unable to resolve identifier TRISB". How to correct that? My program has no error and it is running fine but the warning symbol shows on side.

[@SMtrainingacademy]

Think you have to add header file properly or you have to reinstall the software again

[@fernandohood5542]

Where did you get the device configuration paramaters

[@SMtrainingacademy]

@Fernando Hood You can find the Configuration bits settings in this video link below which is common for this controller kzbin.info/www/bejne/jZecoKeombmhpq8

[@shaileshpatel9662]

Sir thank you so much. But sir can we make library from this code? I tried but failed

[@SMtrainingacademy]

Yes we can @Shailesh Patel I’ll try to do tutorial on that

[@shaileshpatel9662]

@@SMtrainingacademy so nice of you sir, in General public license MPLAB IDE there is limitations of copy pasting codes so if library will there it will be very helpful, i also saw other videos but they are very complicated but yours is easy to understand

[@user-jg5qw2mu8u]

I have a question. Why did we use *str. Its a pointer if i am not wrong?

[@SMtrainingacademy]

Ok I’m fetching the starting address of array instead of whole array so *str is a local variable to the string function which is holding the starting address of array which is passed, as we know array is holding values in contiguous memory locations when we get starting address we can increment and get all the other array element values,

[@user-jg5qw2mu8u]

Thank you very much Sir. Truly appreciate your videos and such a instant response.

[@SportsGyan_]

How to rotate...and where to give command??

[@sureshd1595]

Sir...one doubt ..sir...we told that RS=0 means ..data send to data register and RS=1 means adress to instruction register ..but in the code you used thay in reverse?????

[@dineshkumbhare2952]

Same doubt Although i tried code But its not working in both cases. I'm using pic 18f4520

[@SMtrainingacademy]

First of all sorry for late reply RS=1 means to data And RS = 0 means command This is correct may be I’ll check where it went wrong

[@sd8412]

Sir i run code successfully but i am not able to run simulation plz sir help me

[@SMtrainingacademy]

Can you share what you are getting in proteus any errors..?

[@sd8412]

Accutually, nothing display on lcd and it shows lcd busy

[@SMtrainingacademy]

@@sd8412 reset for several times and check all the wires whether properly connected and if not displaying anything after doing all this you must at least get full dark boxes in all column’s
