SPIKE Compatibility Mode

When the communication protocol is switched to SPIKE mode, the module simulates the output of a SPIKE color sensor. The K210 will generate corresponding color values, reflectance, and RGB data based on the current AI recognition mode.

_Note:_When in SPIKE mode, the module must be connected to a SPIKE device. If not connected, the module will not function properly. To reset to factory settings: First, disconnect the power supply. Hold down the button without releasing it while plugging in a Type-C charger. Once the boot screen appears, release the button to restore default configurations.

When the port protocol is switched to SPIKE mode, the K210 simulates the output of a SPIKE color sensor. In different vision modes, the meaning of the color value, reflectance, and RGB values is as follows:

Note:

  • Color Value Corresponds to the “Color Number” in the SPIKE protocol.

  • (R+G+B)/255×100 This is the calculation method for simulating reflectance, with results in the range of 0~100.

  • For unused fields (such as deep learning, Wi-Fi, etc.), the RGB values may be 0 or random.

  • Line Recognition: SPIKE can only capture the coordinates of the lowest recognized line.

  • Image Transmission Web Joystick: Two bytes represent the X and Y joystick values, with the midpoint being 100.

  • Image Transmission Web Buttons: 0012 3456; when the corresponding button is pressed, the respective bit is set to 1.

  • Image Transmission Keyboard Buttons: 0000 wasd; when the corresponding keyboard key is pressed, the respective bit is set to 1.
