Cytron Technical Forum

Hi,

May i have the header file, as well as the source file for line sensor? I see from the manual, it also has EEPROM and RAM, like G15 servo motor. Thanks.

Hi,

which line sensor did you mean? Cytron has several line sensor: LSS05, LSA08 and also rero line sensor

Hi yonghui,

It's rero line sensor.

Hi Yewys,

Cytron provided the documentation of the internal readable and writeable RAM and ROM area of the sensor in the datasheet they attached on product page. however there is no arduino library available yet, since most user is using rero controller to read from sensor.
This what i can get for you, but you need to further do some amendment to make it work, and also take note of the default baudrate of the sensor.

Hi yonghui,

can i know a bit on how to use the code you shared? is that a kinda header file for arduino? What exactly do i need to change in the code?

Hi Yewys,

im sorry i dont have library for you, the code that i posted are c language functions. u can directly use those functions in your code with some proper intialization codes, or u can create library from it.
