I use ATmega644P and need both UART. This modified loader use any 3 I/O line (RX, TX, LED) for load code from Arduino IDE. Test with ATmega644P (internal RC 8MHz), 38400 baud rates. PC5 = TX line, PC4 = RX line. LED on PB1.

Many publications say about use multi SIM in mobile phones. Very popular Silver cards SIM (and other). SIM holder and SIM is one of lagest element in GSM/GPS trackers. Roundsolutions use ST chip to implement SIM on chip on new mini tracker project. As i know from publications multi SIM cards build on PIC16F876 with 8/32KB EEPROM. I decide implement SIMonChip technology on AVR ATmega168 microprocessor. On of big problem in this project - how to know IMSI and Ki codes. But if you a legal mobile customer you can write request to mobile operator and know this codes (or crack it as describe on kiscan...

Thank to local distributor of Pulse GPS chip antenna ! New variant of uTracker with 4x4 mm GPS antenna pass to designed phase. Preliminary design of uTracker V2 with 34 x 20.5 x 7 mm below. Also no Python now - based on ATMega168/328 (Arduino IDE) with accelerometer and flash memory 32/64 mbit to save waypoints. GSM part build on G100/G200 module from U-Blox and GPS on AMY-5M. One emergency button and 2 LED (highlight). External microhone and speaker for voice calls....

After soldering module CC Debugger (last module) i need to program internal flash with TI firmware. I havn't any TI development tools and decide use Arduino for program. Repository contains PDE file for Arduino and C# project for front-end on PC. First step - connect 3 wire from arduino to CC debugger: PD5 > CC DC line PD6 > CC DD line PD7 > CC RESET line and write sketch to access CC lines from host computer via serial port. Second program on C# to work with CC memory via Arduino and write original TI bootloader for CC debugger (converted to binary format) Third step write original...
