16x2 LCD shows weird values when switching a inductive load. I tried it many way to solve this 16*2 LCD garbled problem, finally I have fixed it my way. From this video you can learn how to solve 16*2 LCD/alphanumeric display ghosting. - แนวปฏิบัติและการใช้ชีวิต
Thanks. You solved my problem. I will test it on my machine
welcome.
If me use i2c? What i can do it also?
hmm
It works also on I²C if you place
lcd.init();
lcd.backlight();
in your loop, but these to function take some 100ms to execute. If time is not an issue, it works. Unfortunately, for my application this workaround is not an option....
My sketch 270 lines and more than 20 if conditions and 5 millis function
For L2c
Haw fix this problem when relay open and closed lcd freeze with unknown letters 😢
Can you help me
Very nice technology
Thanks a lot.
I would love to see how this problem works but I don't understand what you actually did. I know you fixed it and I have the same problem but you moved too fast in the video that I can't understand it.
please watch the video again and again, hope you will understand the coding.
Thank You So Much.
You are welcome.
You run though how to fix it to fast. You say and type nothing. I just don't understand how what you did put on the screen actually did anything.
I reset the LCD initialization after a certain time, so that if any garbled came then it will be resetting. Very simple.
I understand what you added to the code. I did not get to see the code to understand why you added it. I think the video could have explained why it was needed better. So I got nothing out of the video.
@@jessicagriffin6836 I'll try to make another video on it for you.
This method will not work if there is timer looping exist in the program, due to reset, timer also resetting
very useful video sir..pls post video on snubber circuit for triac and mosfet to avoid the junk values..how to isolate the ac load from LCD...pls provide your gmail id sir
Thanks, I'll try. takim.dween@gmail.com
Its not the best solution...the problem is due to noise.
I know, but could you please help me noiseless.
