HUM: RASPBERRY PI DISPLAYS

You are a beginner with Dasduino. Or electronics? A specific module caught your eye, but you do not know how to use it? Do not worry, HUM is here for you! How to Use Module (HUM) is a blog tutorials series by soldered where you will find all you need in order to begin working with your favorite module. Tutorials include: technical characteristics, work principle, instructions on how to connect the module with Dasduino and the basic code. Everything else is left to your imagination.

In this tutorial, we will walk you through certain ways to connect some of the displays for the Raspberry Pi, and for all the tests and examples within this tutorial, we will use the currently strongest version of the Raspberry Pi, model 3 B+.

This LCD is a plug and play and it consists of three main parts: menu board, control panel and the LCD.

All peripherals provided with the LCD:

Specification:
Dimension: 7-inch
Resolution: 1024*600
Power supply: USB
Input: HDMI 1.2, AV, VGA
Consumption: 6-7 W
Mass: 178g

Included in the packaging:
1x LCD display
1x USB power supply cable
1x Remote
1x Driver board
1x Menu board

When connecting the display, we must pay attention to the orientation of the connector that connects the LCD to the control panel:

If you need help with orientation, it can be found on the back of the control panel.

This display is specially designed for the Raspberry and comes with an HDMI interface and a touch screen.

Peripherals provided with the display: 

Specification:
Resolution: 1024×600
Input: touch
Compatibility: any Raspberry Pi (except Raspberry Pi rev. 1 model B and Pi zero that requires an HDMI cable)
Connector: HDMI for the image, touch control requires connecting the LCD via GPIO pins
The backlight can be switched off to conserve battery power.

1. Before connecting the display to the Raspberry, remove the SD card from it and edit the config.txt file.
CODE:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 1024 600 60 6 0 0 0
hdmi_drive=1

3. After editing, insert the SD card back to the Raspberry.
4. Connect the display to the Raspberry using the USB and HDMI cable and after you have done that, connect the Raspberry to the power supply.
5. If you have done everything right, you should see an image on the display.

Specification:
Resolution: 800×480
Input: touch
Compatibility: any Raspberry Pi (except Raspberry Pi rev. 1 model B and Pi zero that requires an HDMI cable)
Connector: HDMI for the image, touch control requires connecting the LCD via GPIO pins
The backlight can be switched off to conserve battery power.

1. Before connecting the display to the Raspberry, remove the SD card from it and edit the config.txt file.
CODE:

max_usb_current=1
hdmi_group=2
hdmi_mode=87

3. After editing, insert the SD card back to the Raspberry.
4. Connect the display to the Raspberry using the USB and HDMI cable and after you have done that, connect the Raspberry to the power supply. 
5. If you have done everything right, you should see an image on the display. 

This is an LCD display based on GPIO pins which is very easy to install. Follow the steps below to get an image on the 3.5 display.

1. You must connect the display to the Raspberry
Connect the display to the pins marked with a red rectangle.

2. Start the Raspberry and connect it to the display via HDMI port.
3. You will be able to see a white image on the small LCD.
4. To enable the image on the small display you have to open the terminal and enter a few commands; enter the commands one by one.
CODE:

sudo rm -rf LCD-show 

git clone https://github.com/goodtft/LCD-show.git 

chmod -R 755 LCD-show 

cd LCD-show/

sudo ./LCD35-show

5. After installing the package, Raspberry will restart and you should see an image on the small display.
6. After the successful installation, you will no longer be able to see the image via HDMI port. If you wish to see the image via HDMI port, follow the commands below.
CODE:

chmod -R 755 LCD-show 

cd LCD-show/ 

sudo ./LCD-hdmi

Or if you want to see the image on the 3.5 display:
CODE:

chmod -R 755 LCD-show 

cd LCD-show/

sudo ./LCD35-show
