HT IRSeekerV2 Block Advanced

Most commonly used Sensor in WRO football:IR Seeker V2 and Compass
But the IR has a lot of problem, the IRSeeker often affected by sunlight or reflections…etc, Most commonly problem is ” Backseat Driver “, it means the ball behind the robot, but robot still go straight, it is classic misjudgment of IRSeeker.

Another problem is the firmware in IRSeeker, will cause some “Small IR sensor”(channel 1-5) value inaccurate, so we add the “offset” options in “Sensor Config” mode, you can custom the offset value of each channel individually.

How to Use

.Fix the bug of HT IIC protocol, prevent some communication failed.

    Hello can you explain why when I put it in DC mode the robot crashes and factory resets?Is this a known issue?

      Did you have the T2h Omni Drive Block or your own block?
      Because some block had there own IR vi,it will cause program crash.
