  4. 3D-Accelerometer to GM862

    Connect accelerometer chip to GM862 tracker To use in Python: class LIS3LV02: def __init__(self): self.LIS3LV02_ADDR = 0x1D # GPIO.setIOdir(13, 0, 0) self.i2cbus = IIC.new(3, 12, self.LIS3LV02_ADDR) self.Error = 0 self.Data = [0,0,0] if (self.i2cbus.init() == -1): print 'LIS3LV02 initialization error (1)' self.Error = 1 elif (self.i2cbus.readwrite('\x20\x87', 0) == -1): print 'LIS3LV02 initialization error (2)' self.Error = 2 else: ret = self.i2cbus.readwrite('\x0F', 1) if (len(ret) == 1 and ord(ret[0]) == 0x3A): self.Error = 0 else: print 'LIS3LV02 initialization error (3) : ' + ret self.Error...

  5. Add accelerometer data to GPS Tracking data

    I decide add 3-axis accelerometer to GM862 tracker and send data to local GpsGate server. Firstly i check this chip (LIS3LV02DL) on standalone microprocessor. I try two variant of microprocessors - ATmega168 (Arduino clone) and EmbeddedMaster (non-TFT). Prepare accelerometer sensor to use I2C protocol and connect to ATmega168 (Arduino) board This code read data from sensor and work fine (now without interrupts from sensor) #include #define OUTX_L 0x28 #define OUTX_H 0x29 #define OUTY_L 0x2A #define OUTY_H 0x2B #define OUTZ_L 0x2C #define OUTZ_H 0x2D #define XAXIS 0 #define YAXIS 1 #define ZAXIS...

  6. How to recovery source python code from pyo file

    This article describe method to recovery source code from compiled python code file. Download pyo code file from device to your computer. If you use linux - skip up to decompyle description. I use windows as host and use next steps to prepare decompile. First download vmware workstation and install it. 2. Create virtual machine and install debian system (i use debian-40r4a-etchnhalf-i386-netinst.iso only with standard system option) 3. Install decompile package apt-get install decompyle 4. Open file /usr/lib/python2.4/site-packages/decompyle/Scanner.py with editor nano /usr/lib/python2.4/site-packages...

  7. Handmake GSM/GPS tracker

    New uTracker on GE865 and UBlox. Small size. Schematic from GM862 Evaluation Board - USB . New version (without Telit and additional chips) - here See this post about how to add accelerometer chip to GM862 Web site and service from gpsgate.com (or install own) no FT232RL - use USB-UART from Philips phone with FT232RL Compelete in box This python script support this tracker (with accelerometer chip) [+] Expand # STATUS pin use as RED led # GPIO2 pin use as GREEN led # GPIO3 (SDA) and GPIO12(SCL) use as I2C bus to LIS3LV02 accelerometer # Auto shutdown on 25% battery or without change 3 attempts...
