Every time I replace an old hard disk by a newer or bigger one I think that I'll wipe it later. Now I have a big amount of hard disks to wipe. Since wiping takes ages, I don't want to use my personal computer for that. I would prefer a small device with low energy consumption just for wiping. That's why I am going to build a "Nukestation". Basically it's just a Raspberry Pi with nwipe on it and a udev-rule for automatically wipe attached hard disks. But some extras would be nice...
Tiva cc3200 is a small board with an integrated wifi-chip. The Linux-kernel needs a few configs to be able to talk to this board using a serial console( via usb):
My plan was to control some power outlets(16 ampere) using any browser(for example with a mobile phone). I wanted to use electronics only and tried to avoid relays.
I created 2 tasks in RTOS: one for reading from uart and one for the display(8x8 LED-Matrix). Both tasks are communicating via queues. The space-invaders-programm gets started by pressing F1. If F2 is pressed, the programm will display all keyboard-input on the led-display.
For my studies I have to work with the Tiva-Board TM4C1294XL. I was quite lost when I tried to find examples in the internet. For all the poor souls who have to work with the tiva-board TM4C1294XL, I am going to publish the code I have to write on it. Here is some simple code for a runnig LED-light. If you push the USR1-button, it will change it's direction.
