Re: Using the PWM pin

wiringPi (as far as I'm aware) is the only library which uses that function.

What are you trying to do?
Question please, is the GPIO 18 pin, 3.3 or 5 volts?

I figured it out, this worked for me.

sudo apt-get purge openjdk-7-jdk
sudo apt-get autoremove

Then:

sudo apt-get update && sudo apt-get install oracle-java7-jdk

Just my opinion, I have worked with serial from the onset back when the fastest was 110 baud. Just time for a change. That's all.

Re: Arduino + Raspberry Pi = Arduino Pi?

It will work, I am presenting do it now via serial however, it would be nice to bypass the UART with a direct connection. Of course this would require a new protocol and libraries on both the arduino end and Pi.

Re: UART

I think but not sure, the Arduino IDE toggles both the DTR and the CTS lines. So I might be ok, will have to test to be sure.

Re: UART

I'm not sure the Pi's UART supports DTR. Regardless of that can you not choose any spare gpio and call that DTR, i.e. connect it to the Arduino and toggle the line in your code? I located the following but not sure how to implement it. http://www.raspberrypi.org/phpBB3/viewtopic.php?p=39241#p39241

Having said that, you aren't really accessing your Rpi. You have turned on a service that gateways WIFI to the internet. The Rpi will then be an IP Router.

Re: Access Pi from Android Tablet

hostapd is used to turn your Rpiinto an access point. Likely not what you want. Depending on what you mean by access, there are a number of apps ranging from telnet/ssh to file sharing (samba) to remote desktop (VNC) that all work with the Rpi and the Droid tablet. It all depends on what you want. ...
