New uTracker on GE865 . Small size. New edition of tracker (SIM300DZ, EB-230/LEA-5S). Add OBD-II (ISO) sensor, accelerometer and RFID reader. Add TR24 2.4GHz module except USB link to host. Change all to SPI (free 3 pins to buttons ?) Add u-blox LEA-5S to schematic (alternative to EB-230) Currently without camera (C328R). Schematic (working copy) USB radio connection dongle schematic and layout GPS tracker layout (plastic box 120x90x30 mm): uBlox GPS reciever LEA-5S 50 channels SIM300DZ (with audio path) 2.4GHz radio adapter accelerometer ATmega324p/644p microprocessor ( sanguino ) internal speaker...
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...
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...
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...
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...
