Learn how to physically connect your Raspberry Pi to a UART Bridge and additionally how to connect to your device and gather logs using PuTTY.
If you are aware of which cable leads to which connection, we can connect it. The Raspberry Pi should be switched off and the switching power supply should not be connected to the socket. The cables are connected as follows: For the connection to the switching power supply you can also us...
Then I attached the Raspberry Pi to the TV, using the HDMI cable, and I attached an USB mouse and USB keyboard to install the OS and get all “wired up”.I then set up the VNC Server on the Pi to be able to connect to it from the Mac. I didn’t really want to keep it ...
In this section we will be preparing your Raspberry Pi by installing all the packages we need to connect to a Wiimote. 1.Now before we start on our first method of utilizing a Wiimote with the Raspberry Pi, we must first ensure that everything is entirely up to date. ...
To tell the Raspberry Pi to automatically connect to your WiFi network you need to edit a file called:wpa_supplicant.conf. To open the file in nano type the following command: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf Scroll to the end of the file and add the following to the ...
