TinyDuino Processors & TinyShields / GPS only printing ****

« on: June 20, 2017, 12:22:55 AM »

Hi

I am using the sample code for the gps-tinyshield (TinyShield_GPS.ino)

It seems that the GPS is recognized but the output it is only *'s.

Sats HDOP Latitude  Longitude  Fix  Date       Time     Date Alt    Course Speed Card  Distance Course Card  Chars Sentences Checksum
          (deg)     (deg)      Age                      Age  (m)    --- from GPS ----  ---- to London  ----  RX    RX        Fail
-------------------------------------------------------------------------------------------------------------------------------------
**** **** ********* ********** **** ********** ******** **** ****** ****** ***** ***   *******  ****** ***   63    0         0 

I changed the bauds to 4800 and 9600 and same output.

Any idea of what else I need to change?

Thanks

TinyDuino Processors & TinyShields / Two Dual Motor TinyShield

« on: May 14, 2016, 10:48:29 PM »

Hi

I need to use 2  Dual Motor TinyShield boards. According to the docs I need to remove a resistor in one of the boards (i.e. R1) The resistors are tiny and I do not wan to damage the board. Is this correct?

Also, how should I declare the motors in the second board, something like:

MotorDriver motor(0);
MotorDriver motor1(1);

// Motor1 board 0
motor.setMotor(1,i);
// Motor2 board 0
motor.setMotor(2,i);
// Motor1 board 1
motor1.setMotor(1,i);
// Motor2 board 1
motor1.setMotor(2,i);

Thanks

TinyDuino Processors & TinyShields / Motor just buzzing with Dual Motor TinyShield

« on: February 29, 2016, 11:04:34 PM »

Hi

I am trying to use a motor with the Dual Motor TinyShield but the motor just buzzes.

The code (I took the simple example) looks ok as I measure the voltage and it increases as it supposes.

The battery that I am using also looks that gives the correct amount of current as if I connect the motor directly it rotates without any problem.

It looks that the board is not providing the enough current to the motors but I do not understand why.

Any ideas?

Thanks
