Apogee v1.00 PCB offer two [http://www.invensense.com/ Invensense] IMU chip options:
* [http://www.invensense.com/mems/gyro/mpu6050.html MPU-6050] : 6 DOF, 3 axis Accelerometer + 3 axis Gyroscope
* [http://www.invensense.com/mems/gyro/mpu9150.html MPU-9150] : 9 DOF, 3 axis Accelerometer + 3 axis Gyroscope + 3 axis Magnetometer


=== USB Modes ===
=== USB Modes ===
* usb plugged before autopilot is powered : enter DFU mode to be flashed
* usb plugged after autopilot is powered : stop ap task, enter usb storage mode to made sdcard content easily avalaible, after the host has mounted;copied;dismounted storage;unplugged usb, ap restart


=== SWD: Serial Wire Debug ===
=== SWD: Serial Wire Debug ===
permits flash and source level debugging via swd part of cheap discovery card, or via more capable, fastest, more expensive probe like black magic probe


=== R/C Serial ===
=== R/C Serial ===
In addition to the classic PPM input, that mostly require receiver modification, one pin of the R/C connector is routed to the MCU UART2 receive input through a '''controlled inverter'''.<br>
This new feature allow '''direct connection''' (3 pin) of several brand off-the-shelf receivers '''without hardware modification''' or external encoder board.
* '''RX2_POL(PB13) = 0''' => R/C serial (Rx2) is '''non-inverted''' : allow use standard polarity serial receivers (Spektrum, FlyElectric...)
* '''RX2_POL(PB13) = 1''' => R/C serial (Rx2) is '''inverted''' : allow use of S.BUS protocol compatible receivers (Futaba, FrSky,...)
(see [[RC_Receivers_and_Radios | R/C Receivers and Radios page]] for serial compatible receiver)


=== Real Time Clock ===
=== Real Time Clock ===
supercap powered rtc, permit to associate correct time and date on sdcard log files, when ap is unpowered between flights


=== Power Switch ===
=== Power Switch ===


'''5V''' power output pin on '''AUX connector''' ("5Vaux",#2) '''can be switched ON and OFF''' on demand using APSW (MCU GPIO output PB12).
* APSW = 0 => 5V Aux OFF
* APSW = 1 => 5V Aux ON (default)
The internal switch TPS2051B is designed to withstand 500mA continuous current and is '''short-circuit and thermally protected'''.<br>
(see [http://www.ti.com/product/tps2051b TPS2051B] datasheet for recommended operation conditions)

Apogee autopilot can reprogrammed in two different ways:
Apogee autopilot can reprogrammed in two different ways:
* using the MCU native DFU USB bootloader over the on-board USB header (so pre-loading an "external" bootloader is useless)
 
* using the MCU native (embedded in rom) DFU USB bootloader over the on-board USB header (so pre-loading an "external" bootloader is useless)
** required hardware : usb cable with usb-mini connector
** required software : dfu_util tool (present in ubuntu repository)
* using the SWD (Serial Wire Debug) connector
* using the SWD (Serial Wire Debug) connector
** required hardware : usb cable with usb-mini connector, molex to 2.54mm pitch pin cable, swd part of a cheap stm32 evaluation board (any discovery board, start @ 8$)
** required software : st_flash and st_util, have to be compiled from source (https://github.com/texane/stlink)


=== Source code ===
==On-board Data Logging==
 
It is possible to write data on the embedded SD card from the main autopilot program. In order to cope with a real-time constraints of the autopilot, a light RTOS called [http://http://www.chibios.org ChibiOS] is used to split the logging task from the rest of the system. Two modules are necessary to enable the logging system: the driver of the SD card system that also handle the file system (using FATFS) and a dynamic memory allocation system called TLSF.
In order to enable this features for your apogee board, you need to select the correct board type and add the required modules to the firmware section of your airframe file (logging is currently only available for '''fixedwing''' firmware):
 
<firmware name="firmware">
  ...
  <target name="ap" board="apogee_1.0_chibios">
    ...
  </target>
  ...
  <module name="tlsf"/>
  <module name="logger" type="sd_chibios"/>
</firmware>
 
This will active the automatic opening of a new log file (30 seconds) after each startup of the autopilot. Then you can freely write ASCII or binary data into this file (see a simple example logging for [https://github.com/paparazzi/paparazzi/blob/master/sw/airborne/modules/meteo/mf_ptu.c meteorological data logging]).
The file is '''automatically''' closed upon battery disconnection, no need to press any button to stop the logging.
 
To recover the data on the SD card, just power up the board '''without''' the USB plugged (otherwise it will enter in DFU boot mode), then plus the USB cable to the board and to your computer. This will stop the main autopilot program and will mount the SD card as a regular mass storage with a FAT file system. The log files are placed in a PPRZ folder. Unplugging the USB will reset the autopilot.
 
In addition to this, you can also load a [http://docs.paparazziuav.org/latest/module__flight_recorder.html '''flight recorder''' module] (it also needs the '''pprzlog''' module for supporting the specific paparazzi binary log format).
 
<firmware>
  ...
  <module name="pprzlog"/>
  <module name="flight_recorder"/>
  ...
</firmware>
 
with the appropriate telemetry file (conf/telemetry/fixedwing_flight_recorder.xml). This will automatically open a second file where telemetry messages described in the FlightRecorder section of the telemetry file will be logged in [[Data_Logger#Storage_format|binary format]].  The files are store in a separated FR folder on the SD card. The decoding procedure is the same than [[Openlog#Decoding|OpenLog]] and is using the '''sd2log''' tool:
 
~/paparazzi/sw/logalizer/sd2log [log_file] [optinal_output_dir]
 
This will produce 3 files: a ''.log'' and a ''.data'' files similar to the normal [[Logs|ground station log]] and ''.tlm'' file that is a simple copy of the binary file (but rename with the same base name than the two others).

Hardware Revision History

Version # Release Date Release Notes
v1.00 07/2013 Initial release of Apogee


Detailed Features

SDIO (MicroSD card)

  • software support available with v5.2 and above
  • hi-cap power designed to give enough time to cleanly save buffer and close file(s) when power outage detected
  • USB-storage mode when plugging an USB cable after startup

6 or 9 DOF IMU

Apogee v1.00 PCB offer two Invensense IMU chip options:

  • MPU-6050 : 6 DOF, 3 axis Accelerometer + 3 axis Gyroscope
  • MPU-9150 : 9 DOF, 3 axis Accelerometer + 3 axis Gyroscope + 3 axis Magnetometer

USB Modes

  • usb plugged before autopilot is powered : enter DFU mode to be flashed
  • usb plugged after autopilot is powered : stop ap task, enter usb storage mode to made sdcard content easily avalaible, after the host has mounted;copied;dismounted storage;unplugged usb, ap restart

SWD: Serial Wire Debug

permits flash and source level debugging via swd part of cheap discovery card, or via more capable, fastest, more expensive probe like black magic probe

R/C Serial

In addition to the classic PPM input, that mostly require receiver modification, one pin of the R/C connector is routed to the MCU UART2 receive input through a controlled inverter.
This new feature allow direct connection (3 pin) of several brand off-the-shelf receivers without hardware modification or external encoder board.

  • RX2_POL(PB13) = 0 => R/C serial (Rx2) is non-inverted : allow use standard polarity serial receivers (Spektrum, FlyElectric...)
  • RX2_POL(PB13) = 1 => R/C serial (Rx2) is inverted : allow use of S.BUS protocol compatible receivers (Futaba, FrSky,...)

(see R/C Receivers and Radios page for serial compatible receiver)

Real Time Clock

supercap powered rtc, permit to associate correct time and date on sdcard log files, when ap is unpowered between flights

Power Switch

5V power output pin on AUX connector ("5Vaux",#2) can be switched ON and OFF on demand using APSW (MCU GPIO output PB12).

  • APSW = 0 => 5V Aux OFF
  • APSW = 1 => 5V Aux ON (default)

The internal switch TPS2051B is designed to withstand 500mA continuous current and is short-circuit and thermally protected.
(see TPS2051B datasheet for recommended operation conditions)

Programming

Apogee autopilot can reprogrammed in two different ways:

  • using the MCU native (embedded in rom) DFU USB bootloader over the on-board USB header (so pre-loading an "external" bootloader is useless)
    • required hardware : usb cable with usb-mini connector
    • required software : dfu_util tool (present in ubuntu repository)
  • using the SWD (Serial Wire Debug) connector
    • required hardware : usb cable with usb-mini connector, molex to 2.54mm pitch pin cable, swd part of a cheap stm32 evaluation board (any discovery board, start @ 8$)
    • required software : st_flash and st_util, have to be compiled from source (https://github.com/texane/stlink)

On-board Data Logging

It is possible to write data on the embedded SD card from the main autopilot program. In order to cope with a real-time constraints of the autopilot, a light RTOS called ChibiOS is used to split the logging task from the rest of the system. Two modules are necessary to enable the logging system: the driver of the SD card system that also handle the file system (using FATFS) and a dynamic memory allocation system called TLSF. In order to enable this features for your apogee board, you need to select the correct board type and add the required modules to the firmware section of your airframe file (logging is currently only available for fixedwing firmware): 

<firmware name="firmware">
 ...
 <target name="ap" board="apogee_1.0_chibios">
   ...
 </target>
 ...
 <module name="tlsf"/>
 <module name="logger" type="sd_chibios"/>
</firmware>

This will active the automatic opening of a new log file (30 seconds) after each startup of the autopilot. Then you can freely write ASCII or binary data into this file (see a simple example logging for meteorological data logging). The file is automatically closed upon battery disconnection, no need to press any button to stop the logging.

To recover the data on the SD card, just power up the board without the USB plugged (otherwise it will enter in DFU boot mode), then plus the USB cable to the board and to your computer. This will stop the main autopilot program and will mount the SD card as a regular mass storage with a FAT file system. The log files are placed in a PPRZ folder. Unplugging the USB will reset the autopilot.

In addition to this, you can also load a flight recorder module (it also needs the pprzlog module for supporting the specific paparazzi binary log format). 

<firmware>
 ...
 <module name="pprzlog"/>
 <module name="flight_recorder"/>
 ...
</firmware>

with the appropriate telemetry file (conf/telemetry/fixedwing_flight_recorder.xml). This will automatically open a second file where telemetry messages described in the FlightRecorder section of the telemetry file will be logged in binary format. The files are store in a separated FR folder on the SD card. The decoding procedure is the same than OpenLog and is using the sd2log tool: 

~/paparazzi/sw/logalizer/sd2log [log_file] [optinal_output_dir]

This will produce 3 files: a .log and a .data files similar to the normal ground station log and .tlm file that is a simple copy of the binary file (but rename with the same base name than the two others).
