Raspberry Pi config.txt

The config.txt you can find on the boot-partition: '/boot/config.txt'
If something doesn't work probably update your Pi-Tron first:

sudo apt-get update
sudo apt-get dist-upgrade

Customized config.txt for the Pi-Tron

### Pi-Tron Settings
## To enable a setting, simply remove the # infront of it

#hdmi_cvt=1024 600 60 0 0 0

### Official RPi Display
#lcd_rotate=2                                                   ##Rotate display by 180°

### Serial interfaces
#core_freq=250                                                  ## needed for the mini-UART
#enable_uart=1
#dtoverlay=uart0,txd0_pin=32,rxd0_pin=33,pin_func=7             ## RS485 on UART0
#dtoverlay=uart1,txd1_pin=40,rxd1_pin=41                        ## RS232 on UART1

#dtoverlay=uart1,txd1_pin=32,rxd1_pin=33                        ## RS485 on UART1 (alternative to above)
#dtoverlay=uart0,txd0_pin=14,rxd0_pin=15                        ## TTL on UART0
#dtoverlay=uart1,txd1_pin=14,rxd1_pin=15                        ## TTL on UART1
#dtoverlay=uart0,txd0_pin=36,rxd0_pin=37,pin_func=6             ## XXX on UART0

### CAN interface
#dtparam=spi=on
#device_tree_param=spi=on
#dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=42
#dtoverlay=spi-bcm2835-overlay
#dtoverlay=spi-gpio35-39

### SDIO interface for 2nd SD card, activates GPIO 22-27
#dtoverlay=sdio

### Real Time Clock DS1307 / RX8900 (onbaord as of REV002)
#dtparam=i2c_arm=on                                             ## sudo apt-get -y remove fake-hwclock
                                                                ## sudo update-rc.d -f fake-hwclock remove
#dtoverlay=i2c-rtc,ds1307                                       ##
#dtoverlay=i2c-rtc,rx8900                                       ## sudo nano /lib/udev/hwclock-set # Comment out the following:
                                                                ##     #if [ -e /run/systemd/system ] ; then
                                                                ##     # exit 0

                                                                ## date && sudo hwclock -r    # Show system time and RTC time

### Activate I2C0
#dtparam=i2c_vc=on                                              ## only activate this if CSI and DSI are not in use
