Playing with raspberry pi and gertboard (part one)
Last few years I follow the raspberry-pi initiative and I really much appreciate it. This year I decide to use this micro computer associated to a gertboard to acheive an old project : building a stand alone oscilloscope.
what I want to acheive :
- Use the gertboard ADC : MCP3002 10-bit (72 sps) or the embed ADC in atmega328p
- Use the AVR atmega328p
- Use a graphical LCD display (AGM 1264F)

Step one : where is my hdmi screen ????
Using my Windows8 PC for raspberry export display
I don't want to use or buy a new HDMI display for this Raspberry pi experiment.So I will use my own laptop. For the very first RP start, You need an HDMI to setup your RP.
- Connect you RP (Raspberry pi)
- With the setup screen activate SSH.
- You could now power off RP and disconnect your HDMI screen.
- Power on RP
- Goes on your windows station and you had to install an XServer and ssh client : you could use mobaxterm, cygwin or a Virtual box with a Linux ISO installed in it (network setup with bridge adapter).
- With this client, open a terminal and connect your RP with ssh :
xhost +
ssh -X pi@ip_addr_of_remote_machine
# the password is rasberry Use man xhost and man ssh for more information
You sould have something like that (with mobaxterm)
just use :
lxsession
After a few second a window should be open with the RP desktop.
How to access my ATmega on my gertboard?
Just have a look at https://projects.drogon.net/raspberry-pi/gertboard/arduino-ide-installation-isp/ this is the "Gordons Projects" blog wich is very well done. You will find out there all that you need for your gertboard.
I just need to add an apt-get update, and all works as expected.
