Hi! Bought your first raspberry pi module? Desperate to switch it on & play with it? Wait a while. Here are some tips to go ahead when you switch on and wait for the display to appear.
1.MicroSD card with minimum 4 GB space (class 10 or above) is suggested to use .Format it with FAT or FAT32 if using Windows based PC.
2.Download OS from www.raspberry.org NOOBS or NOOBS Lite.
3.Copy the OS images and all the content of NOOBS to the microSD card.
4.Next comes the real bottleneck if you don't have HDMI monitor to connect Raspberry Pi HDMI input.
5.To use VGA monitor as a display for Raspberry Pi, buy a HDMI to VGA connector (source-HDMI,Destination-VGA) available in the market(not that expensive).Insert HDMI cable of the connector into the Raspberry Pi HDMI outputt .This finishes the hardware settings.
6.Know that when we download OS content from the raspberry.org , it lacks a file that is essential for the display to appear when we switch on the module for the first time. Some videos on youtube may be useful but not that much capable of throwing full information on CONFIG.TXT file missing from the data that should be saved on microSD card to complete the boot process. Once you have USB keyboard, USB mouse inserted and monitor connected, create a file named as config.txt in a notepad to appear first when you open the microSD card in order to satisfy the booting criteria(strictly don't save it inside any folder, otherwise the RasPi will not boot at all or display any thing).
7.Copy the content below in config.txt just created. It will do the work for VGA monitors.
# Uncomment if you get no picture on HDMI for a default "safe" mode
# Uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan.
# Uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border.
# Uncomment to force a console size. By default it will be display's size minus
# Uncomment if an HDMI display is not detected and composite is being output.
# Uncomment to force a specific HDMI mode (this will force VGA).
# Uncomment to force an HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes.
# Uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display.
# Uncomment for composite PAL
# Uncomment to overclock the ARM. 700 MHz is the default.
8.Insert microSD card with OS information and config.txt file into SD card slot. Power on your Raspberry pi module, RED led lits up, Green led flashes showing up the boot progress and makes display to appear, if everything is fine.
9. It asks for the Wi-Fi network. Enter necessary details. Internet gets connected to the magical single board computer. If you have chosen NOOBS Lite, allow it to download OS from the internet. Otherwise You are done, the system is ready to serve you.
