TFT LCD Basics

[@colescustom]

This was great, I bought a 3.5" TFT (no touch). I found the drivers and was able to get the test programs loaded, but I just didn't know where to start making my own program. I was able to get a simple Hello World type program up and running by examining your code, the comments were helpful.

Cool, thanks.

I'm just learning code for displays, and I believe that you just taught me how to properly display sensor data. Which, hardly anyone describes how to do. I'm trying to make a clock that shows temp, humidity, air quality. And I don't really know what line does what, just basically taking a shot in the dark. But you also simplified getting sensor data from the dht, and displaying it. Time to try this! I've pulled out enough hair, I believe..lol. Thanks for sharing!

Thank you

[@victororo462]

learnelectronics It didn't work. LOL. I got up at 3am, tried it. It didn't work. What would be the code to display raw data from say a gas sensor? The type that are on a small breakout board? I just need the raw data code. Any help would be greatly appreciated!

thank you soooo much! i can use it for my graduation project

WOW! Video from XIX century!!

Awesome videos. Hope your channel continues to grow!

McBryen thank you very much

Set text color (textcolor, backgroundcolor) so it will print green text with black background. No refresh needed. It will overwrite without flickering

merci beaucoup

[@sivanandkamath9389]

How to clear the text only... I'm new to LCD . Can you provide code for that? I created a grey background for the sensor value( time and temperature). Thankyou in adv

Very Cool Thanks a bunch......

Thank you very much for this video.

welcome

good video sir . thank you

Thank you so much

No. You can't wipe the numbered area of the screen. It just lays this area with the changing digits, including black spaces, until it looks a mess. I have only been successful with a complete screen refresh as in your example. A lot of TFT Displays have this problem and it is driving me nuts!!!

[@fredlllll]

of course the whole screen update is slow, think about all the bytes that little microcontroller has to push via SPI or whatever the screen uses.

[@learnelectronics]

fredlllll yep

Dude... you could have used the 5v above D22/23 and GND below D52/53!
