HAT Device
HAT device is test hardware to PC USB interface, which allows accurate measurements from DUT. Device has two switchable power outputs and two switchable USB paths. The power and data lines of the USB can switched on or off separately. HAT device has also four sensor inputs for different sensors. Currently only current measurement sensor is available, but other sensors will be available soon. Sensor inputs without sensor HW can be directly used to measure voltage levels if needed.
HAT device specs
Sensors inputs:
- Analog input resolution is 12bit at 10kHz (for one channel. For two channels 10kHz/2 = 5kHz)
- Analog input voltage range 0 - 2.44V
- Input impedance ~1Mohm
- Sensor inputs have one digital output line (TTL) for controlling sensor (e.g sensor gain)
USB:
- Data+ and data- lines can swithced off or on.
- Power line can be swithced off or on.
- Maximum current 500mA
- LED indicates data lines switch state.
Power
- Absolute maximum input voltage 20V
- Absolute maximum input current 1.5A
- Two power outputs.
- LED indicates power line switch state.
HAT-control
HAT-control is software that is used to control HAT (Hardware Accessory for Testing) device. SW contains two applications. Driver (hat_drv) application controls HAT device via USB. The control SW (hat_ctrl) controls HAT device using driver. Communication between driver and control processes is done using shared memory.
SW Installation
HAT-control sw can be installed to Ubuntu 10.04. It should work also other distributions, but it is not tested yet.
HAT SW dependences:
- libusb-1.0.8
- liblabjackusb
- glib-2.0
Libusb installation:
1. Install libusb-1.0.x package:
sudo apt-get install libusb-1.0
glib-2.0 installation:
1. Install glib-2.0 package:
sudo apt-get install libglib2.0-dev
Liblabjackusb installation:
1. Get exodriver sources:
git clone https://github.com/labjack/exodriver.git
2. Go liblabjackusb folder
$ cd exodriver/liblabjackusb
3. Build library
$ make
4. Install library
$ sudo make install
5. Liblabjackusb needs access to the /dev/bus/usb. Run following commands in labjack-exodriver root folder.
$ cd .. $ sudo cp 10-labjack.rules /etc/udev/rules.d $ sudo udevadm control --reload-rules
Building HAT SW
1. Build HAT SW:
Get sources using git (or some otherway):
$ git clone git://gitorious.org/meego-quality-assurance/hat-control.git
Go to hat-control folder and compile sources
$ cd hat-control $ make
Using HAT SW to control usb and power switches.
1. Connect HAT device to USB port and start HAT driver.
$ cd src $ hat_drv &
Driver should print 'hat_drv: HAT driver started succesfully', if it has started succesfully. It also shows serial numeber of the controller device.
2. Use hat_ctrl SW to control HAT device. For example switch power output 1 on
$ hat_ctrl -pwr1=on
Get all parameters just type
$ hat_ctrl --help
Further development
HAT SW is now very early state. There might be major changes in the near future. Command line parameters might change in near future.
