Imagine you have a system to which you can only SSH inbound but which is unable to reach any host on the Internet outside the local network. For instance, you might have tightened down network access to secure a local CA. Or, like me, you have a Raspberry Pi that you carried around with you… Continue reading Using a reverse SSH tunnel to provide an isolated system such as a Raspberry Pi with network access (well, HTTP)
Using your Raspberry Pi Zero’s USB wifi adapter as both Wifi client and access point
The Raspberry Pi Zero captivates with its small dimensions. This comes at a cost, however, with only one micro USB port available for peripherals of any kind. In this scenario you’ll probably think twice about what you connect to that port. “A USB hub” may sound like a natural choice but if you’re like me,… Continue reading Using your Raspberry Pi Zero’s USB wifi adapter as both Wifi client and access point
tslib not recognizing ft6236 touchscreen due to missing ABS_PRESSURE capability
In my earlier post on Complete rotation support for the Adafruit PiTFT 2.8″ capacitive touchscreen display I described that support for the touchscreen has landed in the mainline kernel in form of the ft6236 driver. I also described that my test program would work correctly now.
Complete rotation support for the Adafruit PiTFT 2.8″ capacitive touchscreen display
In my previous post, I introduced the PiTFT 2.8″ capacitive touchscreen display and showed some test code. If you played around with that, you might have noticed that with the default /boot/config.txt setting of rotate=90 the display is a landscape mode.
Getting started with the Raspberry Pi 2 and a Adafruit PiTFT 2.8″ capacitive touchscreen display
“We live in an age when unnecessary things are our only necessities” (Oscar Wilde, “The Picture of Dorian Gray”) Like many others, I bought another Raspberry Pi 2 to play around with, together with an Adafruit 2.8″ PiTFT capacitive touchscreen (note that Adafruit has various variants of displays that differ only in details such as… Continue reading Getting started with the Raspberry Pi 2 and a Adafruit PiTFT 2.8″ capacitive touchscreen display
