Re: Overclocking Raspberry Pi 3

Has anyone successfully used "arm_freq_min" or "core_freq_min"? They do not seem to ever raise the value for "cpuinfo_min_freq". I'm trying to do this to adjust the minimum operating frequency. Overclocking is nice, but I'd like to bump it up on the lower range for normal operation. I'm looking to b...

Re: Overclocking Raspberry Pi 3

Hi Guys, how to get more voltage than over_voltage=6 ? (1.394V) Look into this: over_voltage – ARM/GPU core voltage adjust. Values above 6 are only allowed when force_turbo or current_limit_override are specified (which set the warranty bit). I believe that was for a RPi2 though, it may still work....

Re: Overclocking Raspberry Pi 3

I've had some decent luck in overclocking. Initially, I was just overclocking to smooth out gameplay in RetroPie. Certain games (particularly N64 and PSP games) were laggy and stuttered. Here are the important bits of my config.txt: # cpu - gpu overclock arm_freq=1400 over_voltage=6 gpu_freq=550 v3d...

Re: Connecting multiple sensors to the same vcc/gnd

I'd like to know if I can connect more than one sensor (each requiring +3.3v) to the same GPIO VCC pin? Would that work? OR will it divide the voltage available to each sensor? To summarise, I have 3 sensors, see below: 1) Each sensor requires +3.3v 2) Each sensor requires ground 3) Each sensor has...

Re: Logitech k400 Plus

I use the original K400. It has worked in Raspbian Jessie, openelec, Ubuntu Mate and RetroPie without any fuss on the RPi3. Best input device I've found and only takes 1 USB port. Seems like the supply line is starting to dry up since the new model is out.

Very nice!

I also snapped up a Pi Zero for $5. I plan on ordering another before they dry up again.

Re: SSD1306 OLED headless system monitor

Here's what I think you need: First take a look at image1. This is a map of the Raspberry PI GPIO I pulled from Google Images. Note the locations of 3.3v, SDA, SCL and GND. Those four pins match those on the ssd1306 and BM280 (and pretty much any other I2C device I've found). You'll want to somehow ...

Re: SSD1306 OLED headless system monitor

Silly question, how did you connect this to the raspberry pi? Initially when testing, I used a breadboard and jumper wire. When I was happy with everything, I soldered up a Y-cable like wille. I've since managed to cram it all inside the case with the assistance of some heavy duty double sided tape.

willie, your code for the BME280 (and subsequent updates) worked wonderfully. I'm cleaning up the output in my script an will post with photos soon. Thank you!

I have got the OLED script presently setup so I can see everything in a few minutes... For editing reasons. Ultimately, once everything is in place and working most of the time the OLED will be displaying the Pi logo (kind of a case badge) with a slower roll for the info screens. Even here in FL, th...
