Beaglebone Black board


https://www.youtube.com/watch?v=UMEUo6Wm6u4



Analog Pins must supply with max voltage of 1.8V

    to get 1.8 V from sensor use Voltage divider with 1.8V (Vcc as Vdd_ADC (1.8V))

Getting started:

https://www.youtube.com/watch?v=c81tmb7WJxw


Step1: Connect Ethernet first then power Beaglebone

Step2: https://beagleboard.org/getting-started

        notedown the IP Address:

    


Step3: Browse the IP address.

Step4: select Cloud9 IDE.

step5: take new select terminal

step6: ifconfig

        notedown IP address: 192.168.7.2

step7: close all


for Using SSH

    open putty----> type IP address----->password

    The BeagleBone Black hardware has two default user names: 'debian' and 'root' . For 'debian' , the default password is 'temppwd' . For 'root' , the default password is empty: '' 



 congrats:


Create New python program:


---->      nano test.py


to save: ctrl+o  ------>  enter ------->

to exit: ctrl +x


to run progra: 

------------->       python test.py



Now how to install VNC
step1: download and install Tight VNC viein our laptop:  https://www.tightvnc.com/download.php


step2: Install VNC server in Beaglebone Black

go to putty :        sudo apt-get install tightvncserver

step3: to run :

        tightvncserver  ------> (enter)

    you can setup password for VNC now

        would you like to enter a view only password---------->n

    now beaglebone ready to use VNC

    vncserver :1 -geometry 1200x800 -depth 24 -dpi 96   -----> enter

step4: goto laptop open VNC Viewer

      type IP address: 

        192.168.7.2:1

    the password setup for VNC now has to enter





Runing Python:

https://www.youtube.com/watch?v=fVSOZDOzTjk&t=219s

open putty in laptop -----------> putty---------->

type -------> python -------------> check version of python

get out of python shell 

ctrl+d


to make directory:

        mkdir mohiddin 

create a python file

         nano hello.py

write program:  ---> save----->exit-------> run



Controlling Digital GPIO with Python (Green Pins)

https://www.youtube.com/watch?v=Yg54VE9CeRE&t=35s


lets  use P9_12 (GPIO_60) and P9_2(DGND) 

connect LED in that


open Putty----->create python file---------> write program


output:







Analog Write (PWM: Purple pins)

https://www.youtube.com/watch?v=vAR8v96J3FQ


using : P8_2(DGND) and P8_13(EHRPWM2B) 

connect LED

write program



Output:

what Duty cycle you give that brighter the LED glows.





Read Buttons Using GPIO Pins from Python(Digital Read)

https://www.youtube.com/watch?v=DdBb6htdO3U


must be : 3.3 V very careful (Vmax) 
 to get max vol to 3.3 v connect Vcc of your circuit to P9_3 pin(VDD 3.3V)

we have to use external pull down and pull up resistors atlease 1kohm resisters.

( This pull up or pull down is nothing but a voltage divider circuit)
