Raspberry Pi Pico W LESSON 22: Using an LCD Display with the Pico W

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this class we will be using the Sunfounder Raspberry Pi Pico W Keppler Kit. It will make things a lot easier if we are working on identical hardware. the link below is to amazon, and is for the identical hardware I will be using in this entire class.

In this introductory video, I will show you how to use the lcd1602 LCD Display with the Raspberry Pi Pico W. I will show you how to load the library onto your pico, and then how to display text on the LCD. We will implement the project using micropython. Enjoy!

I have an electronics backgouund. Trying to teach my kids STEM. This is excellent! 2 thumbs up! Paul is nailing it on all levels!

[Ed-fvrl]

Paul, the homework was straightforward. No issues.

[charlotteswift]

I did this homework before I went on holiday. Something that might help some of you guys is that you can save the lcd1602 library onto the pico itself (in the lib folder) instead of in the same place as your program.

Thanks Paul! I appreciate the great work that you put into producing a great presentation, I am pressing on to catch up!

Woo Hoo. My Raspberry Pi Pico W LCD Display lesson. 😎 Thank you.

Hi Sir, i need to ask, does other IIC models for LCD1602 also work or it only needs to be (HW-061)

[iampad]

Paul, any chance you'll be covering the pi pico PIO assembly programming?

[cbrombaugh]

I AM LEGEND! Although I don't like having to hold the button long so long. The "extra spaces" version looks great but the lcd.clear() version has annoying blinking. Thanks Paul for helping us escape from the PC and monitor.
I really like the Pico W. Two subjects that I hope you cover in the future are wireless (both WiFi and [new] Bluetooth) and asynchronous programs. I want to control my Pico W from my phone.

Can we have one on OLED display please!
Thanks Paul for the awesome videos.

I don't think the 1602 likes the chr(176) so I dropped it. It was showing as a minus sign. I did look at code from a post here and chr(223) works.

[MihaelTolić]

What if my I2C address is different? I don't know where to change it in library. My address is 0x20

Hey, Paul! Here is my solution to last week's homework assignment. I have not viewed your solution yet. That pesky degree character on the lcd screen requires a different code, requiring a bit more of my time, but it was a great exercise. Anybody who had an annoying flashing lcd screen: Just change where you place the lcd.clear() command. Thanks, You are the

Kepler kit was delivered today. Breadboard, Pico W in, hooked up display, charger module, and got the battery on charge. LCD scrolling jokes from a web api. Nice.
Thanks, Paul. And pass one on to SunFounder. Have good, make well.

I ran into problems getting to save the library on the pico so I finally switched out picos. Now after reading some comments I will try work with the lib thing. Thanks Paul you rock!

[slybandit]

Just got myself that kit, and I gotta say you get a TON of stuff for the price, and the quality seems pretty darn good! Luckily I found this playlist because I am a total noob at this, but you make it seem so easy. I have been able to follow along with most videos. I was able to create an LCD that displays the Temp and Humdity readings from the sensor! Love the videos, thanks again!!

[scottpegden]

I can not get the backlight working on the lcd :( the little red light on the back lights but nothing on the screen. I did play with the potentiometer on the back. No errors when I run the code it appears to work. No obvious solutions on the interwebs anyone have this issue? I hope I dont have a bad display.

[keithlohmeyer]

Of course I had to throw in my big digits version. Thanks Paul for all you do.
