DRV8825 stepping motor controller from TI
MSP430 micro-processor from TI
SPI communication to the Beagle Bone
Stand-alone capabilities with full control of stepper motor via RS232
Programmable motor current from 1 to 2.5 amps
12 volts to 45 volt drive voltage capabilities
Evaluation firmware available for the Beagle Bone written in C and runs under the Bone’s Linux Operation System
Motor control parameters loaded into the embedded MSP430 are Motor current, micro-step mode, step count, starting speed, run speed and acceleration/deceleration control
Acceleration and deceleration controller by algorithm in MSP430 micro-processor
Motor movement controlled by algorithm in MSP430 micro-processor
Size Beagle Bone Cape 3.4 X 2.1 inches
Over travel limit detection included
Homing algorithm included
Firmware in MSP430 programmed with Code Composer
MSP430 programmable via JTAG
This is not a bit-switch motor stepper, but a full step controller
