Re: Official display and RPi "B"

Hello Dave, There seems to be no easy way of getting at I2C Bus 0 without soldering jumper leads onto the I2C pins of the Camera connector, or the I2C Bus 0 pull-up resistors R42 & R43 on the underside of the Pi. I solderd 2 wires from the display-connector to R42/43 - it works fine. It is a RPI B R...

Re: Display with Raspberry pi Model B Rev 2.0

HELLO Gordon,
you'll need to connect SDA/SCL to the GPIO
must i connect SDA/SCL to Pin 3 and 5 on the RPI GPIO-header?
Is that all or must i do more?
On my RPI 2 the display works fine, on my B (rev 1 +2) not,
i have done apt-get update , apt-get upgrade and rpi-update.

Re: connect raspberry pi 2 with an old VGA-videoprojector

Nothing works. I found out that the monitor has no DDC, the projector has. So i made an adapter to feed ...

Re: Help with INA125

When the Voltage at the Emitter is 10V, the Voltage at the Base should be about 0,7V higher.
So the Voltage at Pin 4 must be about 10,7V.
Maybe V+ must be = (VREF + 1.25V + 0,7V).

Re: Help with INA125

A reference output of 2.5V, 5V or 10V is available
by connecting VREFOUT (pin 4) to one of the VREF pins
(VREF2.5, VREF5, or VREF10).
VREF10 is Pin 16

Re: Thermal printer USB on Raspberry Pi

You need the usblp.ko kernel modul.
If your raspbian is 2013-05-25-wheezy-raspbian you could
download it from http://www.rieka.de/raspi/3.6.11+/usblp.ko.
Copy it to /lib/modules/3.6.11+/kernel/drivers/usb/misc/usbtest.ko
and
"sudo depmod -a"
Now you can use /dev/usb/lp0 , but only as root.

Dann weiß ich auch erstmal nicht weiter.

Nochmal die Frage:Hast Du die +5Volt vom Raspi-USB-Anschluß irgendwo angeschlossen .
Wenn ja, mach sie mal ab.
Soweit ich mich erinnere sind meine Kabel genau so angeschlossen. Kann ich am Wochenende aber nochmal nachschauen.

Der Hub im Monitor und der Touchscreen wird intern mit Spannung versorgt. Der Raspi braucht über den USB Ausgang keine Spannung an Beide liefern. Darum kann das rote Kabel auch weggelassen werden.
