 +====== Raspbertry Pi ====== 
 +  * Den Pi mit einem Bookworm Image flashen. 32 oder 64 Bit spielt keine Rolle. 
 +  * {{:entwicklung:messy:pasted:20240619-051640.png}} \\ Am besten keinen Filter auswählen, weil man sonst ggf. Bullseye erwischt.
 +  * {{:entwicklung:messy:pasted:20240619-051741.png}} \\ Für diese Anleitung wird Bookworm 32Bit ohne Desktop verwendet.
 +  * Auf dem Pi einloggen und Python checken: \\ <code>
 +pi@TestPi4:~ $ python3 --version
 +Python 3.11.2
 +</code> **Hinweis:** Messy braucht mindestens Python 3.10 !!
 +  * Updates und Tools

 +    * ''sudo apt autoremove -y modem* cups* pulse* avahi* triggerhappy*''
 +  * I2C am Pi aktivieren
 +    * ''sudo raspi-config''
 +  * Bei **Messy WS** den I2C Port drehen (SDA / SCL)
 +    * ''sudo nano /boot/firmware/config.txt''
 +    * ''dtparam=i2c_arm=off'' 
 +    * ''dtoverlay=i2c-gpio,i2c_gpio_sda=3,i2c_gpio_scl=2,bus=1'' -> einfügen
 +    * ''sudo reboot''
 +    * -> erzeugt einen alternativen I2C Bus auf Nummer 3 
 +      * ''ls /dev/i2c*''

 +===== SWAP erhöhen =====
 +  * stop the swap \\ ''sudo dphys-swapfile swapoff''
 +  * Modify the size of the swap. As root , edit the file ''/etc/dphys-swapfile'' and modify the variable ''CONF_SWAPSIZE : CONF_SWAPSIZE=1024'' \\ ''sudo nano /etc/dphys-swapfile''
 +  * Start the swap \\ ''sudo dphys-swapfile swapon''
 +  * Restart \\ ''sudo reboot''
