BrickPi and color sensor


#1

Good night @Matt
I am trying to make a line follower robot with the ev3 color sensor. But it seems that only one sensor works when placed at the brickPi. I have already changed the sensors and the entries. However, it stills only working one.
Is this a problem on my BrickPi, or is this a common issue?
And if it is a common issue, how would i fix it?
Thank you very much, Arthur.

Hi Arthur,

The old BrickPi was designed before the EV3 sensors were released. With the latest firmware, the BrickPi+ has minimal EV3 sensor support.

To use EV3 sensors reliably, you should use the BrickPi3, which was designed from the start to support the EV3 sensors very well.

Hi @Matt. I am already using the brickpi3. At least is the one I bought.

What do you mean by “only one sensor works when placed at the brickPi”?

What do you mean by “I have already changed the sensors and the entries. However, it stills only working one.”?

Does your BrickPi have a power switch? What is the hardware version number printed on the PCB?

Can you share your code, and maybe a picture of your hardware setup?

Try connecting the EV3 color sensor to the BrickPi3 sensor port 1, and then run this example and this example.
