Re: i2c issue - attiny85

Thanks for the input Hampi! I have tested the master code for the pi to communicate with the Arduino Uno. This sample code was actually written for the Arduino, which indeed works flawlessly. Then again the Arduino was built to work with I2c right out of the gate (internal pull ups and such). So sti...

i2c issue - attiny85

Evening! I am at the beginning stages of learning I2C communication. So the sample code im working with works great from Rpi to Arduino. But I wanted to work with the attiny85 chips instead of the Arduino. Im off to a decent start in getting the 85s to work but im running into an issue. Im trying to...

Drop some Knowledge (interfacing)

Guys,

I know very little of these pins. DSI CSI I2C UART... Can anyone point me in a direction of where I can read up on this? Id like to learn about it and understand what each one does.
Thanks!

Re: Awesome, inexpensive 7" monitor!

Professor Harris, Could you please comment on how you set this screen up, modifications to the config.txt file, etc? I picked up one of these and the quality of the display is, in a word, terrible. Quite blurry. So far, I, too, would put this device in the category of you get what you pay for unles...

I like this. Please keep us up to date on the progress. I am also building a security system from scratch. Brand new to the programming game, i have already started with python. Managed to get my contacts working and reporting alarms today. Still on the very basic right now. I am a security tech for...

Re: power over a long distance

Might have to get some specifics. If it is that much of a distance, you may want to work with speaker cable or bigger gauge cable in general. Is good at carrying 12-24 volts, but the amperage diminishes quickly. What are the amps/volts required?

Re: Awesome, inexpensive 7" monitor!

For those who go this route for a monitor. 9v 1500 mA power supply works fine. For the price... the monitor is good. But you get what you pay for. It is not the greatest screen by any means.

This may have been suggested already but when problems are solved here on the forums, it would be great if we can mark the post as "solved".

Open Terminal hotkey?

I know in ubuntu there is a hotkey to open a terminal using alt+t or something like that. Im using wheezy for the pi, is there any hotkey for terminal? How would I go about making one or editing the current?

Thanks!

Re: Awesome, inexpensive 7" monitor!

Hey, Just bought one of these monitors off of Ebay. I am hoping that it is not broken and maybe I am missing something. What power supply are you using for yours? I have tried a 12v 800mA power supply and got it to light up ones with a blue screen. Nothing from the raspberry came through the screen....

Digital Picture Frame as composite video?

Well, I have a few older digital picture frames and i figured maybe I can convert one into a monitor for my Pi. Anyone have any experience with this? I am no electronics expert but i can get my way around. Anyone have an idea on how to achieve this?

Thanks!
