lcd display raspberry pi pico quotation

first of all let me say that I dont have any experience with a Raspberry, Arduino etc. at all, and also dont own any equipment yet. This is more a general question to the more experienced members here, so please bear with me if this comes across as a big unfocused

What I would like to do is built a keystand for my girlfriend in a NES case, that includes a function to display random quotes in the cardridge slot on key press. Basically, everytime she leaves the house in the morning she can press a button and a nice random quote from storage will be displayed on a LED. Thats it!

I have read through a lot of post here and other forums, and I found things similar to this (I found a post about random fortune cookie quotes), but those were all a bit more focused on the coding in itself, which is not really accessible to me (i have only very basic programming knowledge, and I am not sure if I have time to learn the basics fully). I am trying to catch up on everything myself, but thought that asking my be helpful. So I just wanted to ask for opinions on the following things:

3) Is there are generally very well regarded resource for such tutorials? I have started reading the "Beginning with Raspberry Thread" here, but just in case I thought it might be good to ask.

1.14" LCD HAT for Raspberry Pi Pico is a 1.14-inch display expansion board module of 240×135 resolution, 65K RGB colors, clear and colorful displaying effect, with a joystick, designed dedicatedly for Raspberry Pi Pico to expand its engagement via SPI communication by providing standard 40 pins GPIO interface.

Now Create a file "Lcd1_14driver.py" as same content from Pico 1.14" LCD HAT"s github repository in any micropython supported ide (preferred thonny ide) and save it in root location of Raspberry Pi Pico with same name "Lcd1_14driver.py" (without quotes).

You do not need to download it as I will provide the necessary code at a later stage, but you may find it interesting. The pinout for the board and the pins used for the buttons and joystick are provided.

The whole computer graphics system depends on being able to daw a coloured dot, or pixel, at a precise point on the screen. With this particular screen we have 240 rows of 240 pixels making a total of 57600 pixels.

We position each pixel by counting from the top left hand corner of the screen using co-ordinate geometry. 0 to 239 for x values moving from left to right across the screen and 0 to 239 for y, moving down the screen. Remember computers count from zero!

Each pixel can have 32 intensities, or brightness, of red and blue and 64 degrees of green brightness, making 65536 different possible colours - called the RGB565 colour space. ( Green gets the extra bit because human eyes are more sensitive to green light.) Each colour is given a number, from 0 to 65535. (In hexadecimal from 0x0000 to 0xFFFF - from black to white and all the coloured steps in between.) We can hold such numbers in 16 bits or 2 bytes.

LCD screens are useful and found in many parts of our life. At the train station, parking meter, vending machines communicating brief messages on how we interact with the machine they are connected to. LCD screens are a fun way to communicate information in Raspberry Pi Pico projects and other Raspberry Pi Projects. They have a big bright screen which can display text, numbers and characters across a 16 x 2 screen. The 16 refers to 16 characters across the screen, and the 2 represents the number of rows we have. We can get LCD screens with 20x2, 20x4 and many other configurations, but 16x2 is the most common.

In this tutorial, we will learn how to connect an LCD screen, an HD44780, to a Raspberry Pi Pico via the I2C interface using the attached I2C backpack, then we will install a MicroPython library via the Thonny editor and learn how to use it to write text to the display, control the cursor and the backlight.

2. Import four librariesof pre-written code. The first two are from the Machine library and they enable us to use I2C and GPIO pins. Next we import the sleep function from Time enabling us to pause the code. Finally we import the I2C library to interact with the LCD screen.from machine import I2C, Pin

3. Create an objecti2c to communicate with the LCD screen over the I2C protocol. Here we are using I2C channel 0, which maps SDA to GP0 and SCL to GP1.i2c = I2C(0, sda=Pin(0), scl=Pin(1), freq=400000)

5. Create an objectlcdto set up the I2C connection for the library. It tells the library what I2C pins we are using, set via the i2c object, the address of our screen, set via I2C_ADDRand finally it sets that we have a screen with two rows and 16 columns.lcd = I2cLcd(i2c, I2C_ADDR, 2, 16)

6. Create a loopto continually run the code, the first line in the loop will print the I2C address of our display to Thonny’s Python Shell.while True:

8. Write two lines of textto the screen. The first will print “I2C Address:” followed by the address stored inside the I2C_ADDR object. Then insert a new line character “\n” and then write another line saying “Tom’s Hardware" (or whatever you want it to say). Pause for two seconds to allow time to read the text.lcd.putstr("I2C Address:"+str(I2C_ADDR)+"\n")

9. Clear the screenbefore repeating the previous section of code, but this time we display the I2C address of the LCD display using its hex value. The PCF8574T chip used in the I2C backpack has two address, 0x20 and 0x27 and it is useful to know which it is using, especially if we are using multiple I2C devices as they may cause a clash on the bus.lcd.clear()

12. Turn the backlight back onand then hide the cursor. Sometimes, a flashing cursor can detract from the information we are trying to communicate.lcd.backlight_on()

13. Create a for loopthat will print the number 0 to 19 on the LCD screen. Note that there is a 0.4 second delay before we delete the value and replace it with the next. We have to delete the text as overwriting the text will make it look garbled.for i in range(20):

Save and runyour code. As with any Python script in Thonny, Click on File >> Saveand save the file to your Raspberry Pi Pico. We recommend calling it i2c_lcd_test.py. When ready, click on the Green play buttonto start the code and watch as the test runs on the screen.

I just got myself a Pico Pi to learn electronics and MicroPython. I was digging in my pile of "I bought this to do something one day with it, but never did" and found an old DMF5001NY-L 1 from Optrex. It has a 20-pin connector connected to a Toshiba T6963C driver with an 8-bit data bus. I was hoping to use it for a project on my Pico or at least see if it is still in working condition.

New to Pico so I need some help here. I know I can use a 16x2 LCD via a serial bus using the I2C backpack adapter. I was hoping that something like that exists for this type of LCD screen.

Of course, [Kevin McAleer]’s project is strictly in the “Just for Fun” category. But that doesn’t mean it’s not at least somewhat useful. The design is pretty close to the original PKE meter, with a little bit of creative license taken to make it easier to build. Guts include a Raspberry Pi Pico W and a generous 320×240 LCD display. The body of the meter is entirely 3D printed; design files are of course available. The meter’s arms are geared together to move with a single hobby servo.
