To replicate add this line to the end of setup in the MotorEncoder example:

evshield.bank_a.motorRunUnlimited(SH_Motor_1, SH_Direction_Forward, SH_Speed_Slow);

Upload the program and press GO to start it. Notice when you hit the left arrow to reset the encoder positions the motor is set to full speed for a moment before losing its momentum and dropping back to SH_Speed_Slow. Also unplug and reconnect the motor, a similar issue occurs.

Now replace that line with:

evshield.bank_a.motorRunUnlimited(SH_Motor_1, SH_Direction_Forward, SH_Speed_Fast);

Notice (by ear) there is little-to-no difference in speed.

The motorIsTachoDone and motorIsTimeDone functions return "0" regardless of the state of the motors.

For example, the motorRunTachometer functions correctly and the motors stop near the target, however it is impossible to detect completion using the motorIsTachoDone function.

I see a lot of functions in the code where the return statement is missing or is kept inside if blocks that may not execute. I am very surprised to see such badly written code which doesn't conform to any standards. Does anyone know the reasoning for this?

An example:

uint8_t EVShieldBank::motorWaitUntilTachoDone(SH_Motor which_motors)
{
  uint8_t s;
  delay(50);  // this delay is required for the status byte to be available for reading.
  s = motorIsTachoDone(which_motors);
  while (( s & SH_STATUS_TACHO ) != 0 ) {
    delay (50);
    s = motorIsTachoDone(which_motors);
  }
}

I cannot figure out how to connect a RCBCONN01 RC Battery Pack Connector cable to my EVShield with Arduino Uno compatible board bundle,
I spliced the cables on the battery pack connector and tried to insert them into the green jack on the EVShield.
However, they do not click in or attach firmly as I thought they would
I must be missing something - but I cannot see it

Thanks for any help

Hi,

I would like to know if it is better to use a DC Adapter for Arduino One or some solution for EVShield?
http://playground.arduino.cc/Learning/WhatAdapter

I'm missing some of the defined motor status flags (defined in evshield.h). Actually there is no way to detect stall or overload.
Why is in evshield.cpp SH_MOTOR_STALL commented?
Also the following flags aren't implemented?
SH_STATUS_RAMP
SH_STATUS_MOVING
SH_STATUS_BREAK
SH_STATUS_OVERLOAD

Thanks in advance.

I know you apperently fixed this issue in the past.
But "SH_Completion_Wait_For" does not have any effect on running an EV3 motor.

Doing initial tests and had problem with twi.h when compiling. Resolved error by replaced changing code in BaseI2CDevice to:

extern "C" {

if ( ARDUINO == 10608 )

//#include "../../hardware/arduino/avr/libraries/Wire/src/utility/twi.h"
//above code throws error - below allows to compile - absolute addressing is a problem for libraries

include "utility/twi.h"

elif ( ARDUINO == 10605 )

include "../../hardware/arduino/avr/libraries/Wire/utility/twi.h"

else

uint8_t twi_writeTo(uint8_t, uint8_t*, uint8_t, uint8_t, uint8_t);

endif

}

Not sure if this problem exists in other code - will check when I do more testing.

softi2c doesnt build.
this is caused by the following:
uint8_t* SoftI2cMaster::readRegisters(uint8_t startRegister, uint8_t bytes, uint8_t* buf){
//delay(20);
if (!buf) buf = _so_buffer;
bytes = min(bytes,BUFF_LEN); // avoid buffer overflow
memset(buf, 0, BUFF_LEN);
_error_code = 0;
// issue a start condition, send device address and write direction bit
if (!start(deviceAddr | I2C_WRITE)) {
_error_code = 2;
return false;
}

the compiler does not allow to return false as an uint8_t*.
for c++11 this should be the nullptr.

When using the motor control functions motorRunSeconds, motorRunTachometer, motorRunDegrees, and motorRunRotations, the SH_Completion_Wait_For parameter does not work reliably. Mindsensors support team is currently working on a fix for this issue.

Speed is not controllable on Bank A Motor 1 when using Arduino IDEs that have an I2C frequency other than 50000. Mindsensors support is currently working on a fix for this issue.

I have 13 evshields. 3 of them have problems syncing. This problem is significantly worse with the Arudino Uno clones that come with the EvShields but exist on Ardunio Brand and DFRobot brands as well.

We are using a touch and drive example as a basis for this but the problem also exists when trying to upload default Blink to the device with the shield mounted. When you remove the shield it loads just fine.

Any ideas:

It appears that EVs_Color is unfinished and only operates as a light sensor and can't operate as a colour sensor.

When writing to motors on different banks there is sometimes a loss. We have seen not every command is executed and motor control can be unreliable. Mindsensors support team is currently working on a fix for this issue.

When running both motors synchronously on Bank B using motorRunSeconds, motorRunRotations, motorRunDegress, or motorRunTachometer, the motors will not perform as desired. Mindsensors.com is currently working on this issue.

BaseI2CDevice.cpp is including MSTimer2.h but the file is named MsTimer2.h.

Hi,

I would like to know if exist a way to know what is the level of the battery connected to EVShield.
