If you want to run a motor with EEROS you need to define a Peripheral Output with the respective
signalId used in the HAL configuration file. As you can see in the configuration file HwConfigBBBlue.json the
subdevice2 comprises the analog outputs for the motors. In the EEROS application for the Delta roboter you can set a motor voltage of -8.0V to 8.0V. The HAL gets this values and wraps it to match the values of the robotics_cape_library which then runs the motors with the desired voltage.
The Delta roboter three motors with encoders and gears. You'll find the datasheets in Hardware Components.
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.
