DSTAR-Hotspot with Arduino RPi.

D-STAR hotspot with open HW and SW under GNU GPL2 based on DV-MEGA - by Guus van Dooren (PE1PLM) and DVSP2 by SQ9MDD.

Tested with Raspberry PI 2 and Western D-STAR image.

TODO

  • add partlist
  • add more info about HW and building
  • add gerber files for production
  • add configuration for Ircddbgateway and D-STAR repeater

How to compile SW for Arduino

Use Arduino 1.5.X

Before programming Arduino be sure the "HardwareSerial.cpp" under Arduino instalation folder\hardware\arduino\cores\arduino is changed.

From:

#if (RAMEND < 1000)
#define SERIAL_BUFFER_SIZE 16
#else
#define SERIAL_BUFFER_SIZE 64
#endif

To:

#if (RAMEND < 1000)
#define SERIAL_BUFFER_SIZE 16
#else
#define SERIAL_BUFFER_SIZE 128
#endif

HOW to remove console from serial on RPi

$ sudo nano /boot/cmdline.txt

From:

 GNU nano 2.2.6          File: /boot/cmdline.txt
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait 

To:

dwc_otg.lpm_enable=0 rpitestmode=1 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

$ sudo nano /etc/inittab

From:

 GNU nano 2.2.6          File: /etc/inittab
#Spawn a getty on Raspberry Pi serial line
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

To:

#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

You need configure Ircddbgateway and D-STAR repeater package to run hotspot
