 ====== Hardware Abstraction Layer ======
-EEROS for the Beagle Bone Blue is using the [[https://github.com/StrawsonDesign/librobotcontrol|robotis_cape_library]]. You'll find the wrapper and its functions in the ''bbblue-eeros'' folder. To learn more about the hardware abstraction layer read [[http://wiki.eeros.org/eeros_architecture/hal/start|HAL]]
+The HAL is the same as [[:hal|]] with an additional motor and encoder for the TCP.
-=====Configure the Encoder Inputs =====
-The Delta roboter has two different motors with different encoders and gears. You'll find the datasheets of the two types in [[hardware|]].
-==== Encoders on the Axis Motors ====
-The axis motors are equipped with a gear with the ratio of //76:1// and with an encoder //ieh2-4096//, which provides //4096 lines per revolution//. The quadrature decoder function, which counts the encoder ticks, delivers 4 counts per line. \\
-To account for this in the configuration file of the HAL, we add three blocks. These blocks mirror the physical behavior of the decoder, encoder, and gear.\\

-The total scale will be calculated by the HAL as (76 * 4096 * 4) / 2π.
 ==== Encoders on the Tool Center Point Motor ====
 The TCP motor are equipped with a gear with the ratio of //120:1// and with an encoder //hem3-256w//, which provides //256 lines per revolution//. The quadrature decoder function, which counts the encoder ticks, delivers 4 counts per line. \\
