It must also be ensured that SPI is activated: sudo nano /etc/modprobe.d/nfĬomment out the corresponding line: #blacklist spi-bcm2708

In the menu, you choose “Expand Filesystem” (first point) and confirm (also the question about the restart). Zum Beispiel kannst du Pin 1 (1A) als Eingang nehmen (Ausgang von 74HC4040) und Pin 2 (1Y) als Ausgang zum Pin 5 (WR) des Displays.įirst of all, the system has to take the space of the whole SD card, if you have already done that, you can skip it.

Therefore, we look at the different components in detail:ĭieses Bauteil hat mehrere Inverter. In addition, the outputs are not all as shown on the right side, but distributed. The connections of GND components are not shown for clarity, but of course still have to be connected to the GND of the Pi. The connections are as follows (on the left are the pins of the Pi, on the right those of the display). Some pins of the Pi (like MOSI, SLCK, …) are used more often, this should be considered when connecting.

The other pins of the display must be connected via the blocks. Here you can put D_Penirq on any free GPIO, you just have to specify this later. Here are those pins that are directly connected to the Pi. If someone, like me, would like to solder the whole thing together and make an attachable shield on the TFT, needs a 2×20 socket strip, a breadboard and soldering tools. The smaller touchscreens are already available from 10-20€, but the advantages are big (especially with regards to a GUI for home automation, for example) and the effort is relatively low, as I’ll show.Īs an example I will use a 3.2” SainSmart touchscreen, however, any other supported touch screen can be used as well. Sooner or later, most hobbyists will buy a touchscreen.
