Mar.14-16 RPi moving along

Preliminary information found and tested. 
Next step is with 4DIAC. [next post Wed or Fri]

First RPi boot (Mar.14)
Hardest part was to get all the connectors.
Took less than 30 minutes after had everything.

• Power supply 1.2A / 5V
• Model B instructions says 700mA to 1200mA
• 700mA what chip needs as minimum; may include keyboard and mouse.
• 1200mA so board does not get too hot.
• with micro USB connector 
• [Mobile phone charges can be used if have around 1000mA or more]
• HDMI to DVI-D connector  (to display)
• Select B for digital output
• Keyboard and mouse
• Recommend Ethernet cable 
• No network to plug Ethernet into in lab (due to firewalls)
• Used wireless with mobile phone

First boot worked as documented. 

Commands to remember:

• sudo raspi-config to if forgot anything, like turn on ssh.
• startx  to  graphic interface

Second RPi "configuration" addition and Blinky (Mar.16)

• LapTop and RPi connected to Mobile phone as router
• RPi wifi via LinkSys WiFi USB stick
• wifi via DLink USB with Mobile phone
• see book True WiPi 
• using wpa_gui
• Add and connect to mobile phone
• LinkSys WiFi USB stick
• no USB port extender so plugged in/out keyboard and mouse
• obviously not good idea long-term
• connect using Putty to text screen
• SSH 
• turned on for RPi via raspi-config
• but setting not kept (how)
• use PuTty for laptop
• WPA2 choices
• WPA (TKIP) on mobile phone, but WPA personal on RPI
• AES-based CCMP:  WPA2(AES) on mobile phone and WPA2 CCMP on RPi
• Minor problem: At first the Kindle was on and connected to mobile phone taking 2nd of the 2 connections allowed.

1st RPi test : Turn LED on (Mar.16)
just connect ground pin and 3.3V source pin or 5V source pin (brighter)

• RPi Pins for LED
• All RPi Pins
• General LED background information
• Garage Lab
• With Ada Pi Cobbler

2nd RPi test : Control LED by GPIO (Mar.16)

• Using pins 6 Ground and GPIO 17
• Install of WiringPi

On to C++ and 4DIAC now...
