Turntable Procedure
Hardware
Pictures
Components
- audio-technica AT-LP120_USB Direct Drive Professional Turntable
 - Olimex LPC H2148
 - Omron rotary encoder
 - Lisa/L+IMU, Xbee 2.4Ghz modem set, fibreglass mounting plates and general wiring components
 
Wiring
Encoder to LPC
- Black (common) to EXT2 GND
 
- Red 5~12 VDC to EXT2 Vin(5v)
 
- White OUTA to EXT1 PO.22
 
LPC to LPC
- EXT2 3.3v to EXT1 PO.22 (pull up resistor)
 
Software
LPC Code Modifications
In case of USB 2.0 A-B cable operation, ~/conf/airframes/Poine/turntable.xml has to be amended, as follows, and saved as ~/turntable_dev_usb.xml:
| File: conf/airframes/Poine/turntable_dev_usb.xml | 
main.CFLAGS += -DUSE_USB_SERIAL main.srcs += $(SRC_ARCH)/usb_ser_hw.c main.srcs += $(SRC_ARCH)/lpcusb/usbhw_lpc.c $(SRC_ARCH)/lpcusb/usbinit.c main.srcs += $(SRC_ARCH)/lpcusb/usbcontrol.c $(SRC_ARCH)/lpcusb/usbstdreq.c main.CFLAGS += -DDOWNLINK -DDOWNLINK_TRANSPORT=PprzTransport -DDOWNLINK_DEVICE=UsbS #main.CFLAGS += -DUSE_UART0 -DUART0_BAUD=B115200 #main.srcs += mcu_periph/uart.c #main.srcs += $(SRC_ARCH)/mcu_periph/uart_arch.c #main.CFLAGS += -DDOWNLINK -DDOWNLINK_TRANSPORT=PprzTransport -DDOWNLINK_DEVICE=Uart0 main.srcs += subsystems/datalink/downlink.c subsystems/datalink/pprz_transport.c #main.CFLAGS += -DMB_TACHO #main.srcs += $(MB)/mb_tacho.c </makefile> </airframe>  | 
A new turntable session has to be added to ~/conf/control_panel.xml:
| File: conf/control_panel.xml | 
  <session name="Flight with USB-serial_TT modem">
      <program name="Data Link">
        <arg flag="-d" constant="/dev/ttyACM0"/>
        <arg flag="-nouplink" constant=""/>          
        <arg flag="-s" constant="115200"/> 
      </program>
      <program name="Server"/>
      <program name="GCS"/>
    </session>
