BeBoPr++

Descriptions
The BeBoPr-plus-plus is the 3rd generation BeBoPr cape. It is the successor of the BeBoPr-plus cape and the original BeBoPr Cape. The BeBoPr++ Cape provides all the necessary I/O to control a Mendel/Reprap 3D-printer, or other (multiple axes) stepper driven devices:
 * 3 Analog inputs optimized for thermistors.
 * 6 Digital inputs for limit switches.
 * 3 High-power PWM outputs for heater(s) and/or fan.
 * Multiple axes steppermotor interface, 5 axes with external drivers or 4 axes with plug-in Pololu/StepStick modules.
 * Single supply (12-24 Volt) operation. The integrated 5V/2A switching stepdown convertor powers the Cape, the BeagleBone, and external sensors.
 * All I/O is protected to prevent damage to the BeagleBone by accidental short-circuits or wrong logic levels.
 * Steppermotor operation at up to 36 Volts, depending on the drivers being used.
 * Multiple LEDs, mounted near the input and output connectors provide status information.

All 'hard' realtime control, e.g. step pulse generation, acceleration etc. runs on a dedicated PRU coprocessor that is part of the AM335x on the BeagleBone. The 'soft' realtime control, e.g. traject planning, temperature control etc., runs on the ARM processor under Linux.


 * The stepper control code accelerates and steps all axes simultaneously at up to 60 kHz steprate.
 * The step-pulse duration on the E-axis can be controlled for laser engraving/cutter applications.

All Linux code is Open Source. A license for the coprocessor code comes with the board, the code is provided as embedded binary module.
