Re: raspberry pi B+ rpi_installer_08-19-12.zip

Any kernals before June 14 won't work 'out of the box' on the B+ due to the change of USB and Ethernet chip (not having the drivers added). If you can use a TTL - USB cable, or put the SD in to a B and then run upgrade and dist-upgrade - You may be able to use it, but for the hassle it's better to b...

Re: Problem with i2c 0 bus

You can read off the eeprom in to an eep file after writing, and then use eepdump to convert the file so it is readable - All quick and painless. It wouldn't work of other eeproms from different systems though I doubt

Re: Problem with i2c 0 bus

Now that makes more sense, it didn't seem to occur to me as I've been trying to get it to work to program the eeprom before being able to play with it.

Can't wait for the documentation about driver loading and such when it is ready

Problem with i2c 0 bus

I'm hoping I am missing something really simple, but after spending 2 days, and restarting from the beginning with a fresh SD, I cannot detect anything on the ID_SC ID_SD line. I have plugged the eeprom on to the GPIO 2+3 i2c and can detect it without any problem showing on 0x50. I have i2c-dev in m...

Re: Pi B+ won't shutdown? Tying pin 28 to GND seems to solve

I don't suffer the spontaneous reboot problem, but out of curiosity just had to try the halt and finger touch restart - And so it does! I don't use noobs, purely as I run headless using WiFi/USB-TTL cable so I just want to just SSH straight in to Raspbian, so cd /boot and sudo wget (renaming the old...

Re: Eureka Moment: WiFi config in /boot

Just noticed the middle default should be mobile in the interfaces, as it'll get its own IP settings from the access point, but I'm sure you'll get the point ;)

Good luck!

Re: Eureka Moment: WiFi config in /boot

id_str is the name you give each wifi setting, as on mine I only use the one network, if I use my Pi elsewhere (home, mobile access point, work) it'll look like this: network={ ssid="Home" psk="WPA_PASS" id_str="home" } network={ ssid="MobileAP" psk="WPA" id_str="mobile" } network={ ssid="Netgear" p...

You can set IP's for either wlan0 or eth0, and have a seperate for each Wifi....

Re: Eureka Moment: WiFi config in /boot

Brill!
If your not using eth0 just take the references out otherwise take out this line:

Code: Select all

iface eth0 inet dhcp
WPA and WPA2 will use key mgnt, but WEP is different as you need the key1,2,3,4 but not sure of them off the top of my head (who uses WEP now'a'days?)

Re: Eureka Moment: WiFi config in /boot

With it being in the boot folder you just update that conf file, change the SSID and passkey and put back in the Pi and your off.... Or create the list of networks one after each other that you'll use and it will run down the list looking for each network until it connects automatically

Re: XBMC OpenELEC and LCD HD44780 via GPIO

Depending on how your wiring them, they will both share the pin, you may have to cut the wires to join both +5's to the same connector. If you wish (I haven't tried it my self but no harm in trying) and try hooking LCD to 3.3 to see if that is sufficient

Yes you can, but you'd need to choose a free gpio pin and adjust the LCDd.conf to suit your pin adjustment

Re: Robot feet

Servo controlled arms would be easy, but having feet which can balance and walk would be difficult in my eyes as to walk on 2 legs you need to 'rock the bot' to shift balance on to each leg to move (If you get me). What about starting with 4 legs?

LCDd would sort out itself what to write on the screen providing the size=16x1 is set correct.

Re: XBMC OpenELEC and LCD HD44780 via GPIO

Glad the tutorial helped, have you got the setup on a breadboard? If so check all the connections are tight as a loose connection can result in gibberish. Also inspect the LCD itself for poor soldering. To restart run the " sudo /etc/init.d/LCDd restart " command, Xbmc will reconnect after a few sec...

Re: XBMC OpenELEC and LCD HD44780 via GPIO

Not currently having a setup to test as far as I know you can set (check with google) the tag dimonscreensaver in either LCD.xml or advancedsettings.xml and this will allow the screen backlight to turn off when the screensaver kicks in
