The only difference between the Magic Mirror and the Pipad is that the Magic Mirror uses a one-way mirror and the Pipad use Toughened Glass.
User Guide
To use the Magic mirror, you can use the pre-configured image which we provide or configure it yourself with the original Raspbian image.
It is recommended to install pre-configured images for newbies or first-time installation. The pre-configured images have already installed the required libraries and drivers, and the program runs automatically after booting.
Method 1. Pre-configured image
- 1. Download the pre-configured image and write it to your SD card.
- 2. Add the following lines to wpa_supplicat.conf files in the BOOT directory. (if you didn't find the files, create them.)
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US
network={
ssid="your_real_wifi_ssid"
psk="your_real_password"
}
Note: you need to change your_real_wifi_ssid and your_real_password" to the real ssid and password.
- 3. Inset the card to Raspberry Pi and power on it.
Method 2. Configure image manually
- 1. Write a Raspbian image
- Download the latest Raspbian image from the Rasberry Pi website and write it to an empty micro SD card.
- Create a new Txt file under the BOOT directory of the micro SD card and name it SSH.
- Modify the config.txt file which is located in the BOOT directory, and add the following lines to the config.txt file:
hdmi_group=2 hdmi_mode=82 hdmi_cvt 1920 1080 60 6 0 0 0
- Save and insert the micro SD card into Raspberry Pi.
- Connect the Magic mirror to the network and power on Raspberry Pi.
- After booting, you can access Raspberry Pi via SSH, or directly connect the keyboard and mouse.
- 2. Install WM8960 sound card driver
- Open the terminal and use the following commands to install.
git clone https://github.com/waveshare/WM8960-Audio-HAT cd WM8960-Audio-HAT sudo ./install.sh
- Modify the config.txt file, remove the following line from the file, or comment on it.
#dtparam=audio=on
- Then reboot Raspberry Pi.
sudo reboot
- After rebooting, check the driver by the following command.
sudo dkms status
- If you can get the information below, it means that the driver was installed successfully.
