How To Assemble

Note: please download the code to the host control first, and test it before assembling!

Step 1: Insert the host control (Raspberry Pi ZERO, pico, esp32-s2-pico) into the back of the "1" board. The pico and esp32-s2-picode USB ports are facing outwards without screws. Raspberry Pi needs (2x copper posts + 4 silver-white screws) to fix the 2 holes on the non-interface side;
Step 2: On 1 to 2, you need to pay attention to 1. You must put the 4 buttons on the side before you can put them in. Then use the patterned copper column, first lightly lock the diagonal alignment holes, and then lock the rest , and then all tightened (4 single-headed copper posts);
Step 3: Install 3 on 2, use black screws, in the same way, first lightly lock the diagonal alignment holes, then lock the rest, and then tighten them all (4 black);
Step 4: Insert the LCD into the 1 board, the side with the buttons is the back of the LCD, then put the glass cover, and lock it with silver-white screws (6*2 silver-white);
Step 5: Cover 4 on top of 2, use black screws to lock the diagonally aligned holes first, then lock the rest, and then tighten them all (4 black).

Working With Raspberry Pi Zero

Please test the code first before assembling.

Install Library

#python2
sudo apt-get update
sudo apt-get install python-pip
sudo apt-get install python-pil
sudo apt-get install python-numpy
sudo pip install spidev
sudo pip install rpi_ws281x
#python3
sudo apt-get update
sudo apt-get install python3-pip
sudo apt-get install python3-pil
sudo apt-get install python3-numpy
sudo pip3 install spidev
sudo pip3 install rpi_ws281x

Download & Test The Demo

Open the terminal of Raspberry Pi, run the following demo:

sudo apt-get install unzip -y
sudo wget https://files.waveshare.com/upload/a/ae/LCD-Clock-A-Code.zip
sudo unzip ./LCD-Clock-A-Code.zip -d ./LCD-Clock-A-Code/
cd LCD-Clock-A-Code/rpi/

Run The Program

Please keep it in the directory of the previous step. In order to display the time normally, please follow the steps below:

For the first configuration, the default time of the program is the system time written into the RTC, so write the time for the first time. If the time is not correct, the system can be adjusted to the correct time or adjusted through the menu during runtime.

ls -l
sudo python main.py

Open main.py and comment the forty-second line of code:

sudo nano +42 main.py

Then enter # to comment, press ctrl+x and then press Y, and press Enter to comment.

Set Auto-start

sudo nano /etc/rc.local

Add the following before exit 0:

sudo python /home/pi/LCD-Clock-A-Code/rpi/main.py &

Note that you must add "&" to run in the background, otherwise the system may not be able to start.

Reboot the device:

sudo reboot

Demo

Customize Dial Plate

If you need to customize the dial plate, please open main.py:

sudo nano +18 main.py

This is the directory of digital picture files. You can change the letters after /numpic/ to four types: A, B, C, D. If you have any custom ones, please create a new directory E or other under /numpic/, code This is also changed to relevant;
Similarly, the custom menu is the same, change the code line 19.

Arduino IDE Series

Install Arduino IDE

Download the Arduino IDE installation package from Arduino website.
Just click on "JUST DOWNLOAD".
Click to install after downloading.
Note: You will be prompted to install the driver during the installation process, we can click Install.

Install Arduino-Pico Core on Arduino IDE

Open Arduino IDE, click the File on the left corner and choose "Preferences".

Add the following link in the additional development board manager URL, then click OK.

https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:

https://dl.espressif.com/dl/package_esp32_index.json,https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

Click on Tools -> Dev Board -> Dev Board Manager -> Search for pico, it shows installed since my computer has already installed it.

Upload Demo At the First Time

Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).
Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
Click Tool -> Dev Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
After setting, click the right arrow to upload.
- If you encounter problems during the period, you need to reinstall or replace the Arduino IDE version, uninstall the Arduino IDE needs to be uninstalled cleanly, after uninstalling the software you need to manually delete all the contents of the folder C:\Users\[name]\AppData\Local\Arduino15 (you need to show the hidden files in order to see it) and then reinstall.
