HW

• Motor Controller
  • Arduino Micro for Motor Speed Controller (with display and some buttons - for details see Leonardo_wLCD_protobase)
  • IRLZ34N N-Channel Logic Level Power Mosfet
  • MBR1660 as freewheeling diode
• POV Controller
  • Pololu A-Star Mini LV as POV Controller
  • LEDBoard_4x4_16bit for output
  • 2x SFH4550 IR-LED 850nm 3° (one as sender and one as receiver)

Software

SW_motordriver_wTacho

based on Leonardo_wLCD_protobase

added IRLZ34N N-Channel Logic Level Power Mosfet and fast Diode for driving the Motor.

shows the current RPS (revolutions per second) on the LCD.

SW_simple_pov_TLC5971

based on LEDBoard_4x4_16bit_HWTest. implements basics to generate some very simple test-patterns for POV. uses the ulrichstern/Tlc59711 library.
with my changes in idx lookup branch the setting of the Color information per LED tlc.setRGB(idx, r, g, b); call is way faster:

• orig ~49us
• lookup_idx ~9us

but currently this branch relies on c++14 features that require the arduino beta version..

for now you can use arduino-PR-beta1.9-BUILD-71 and
enable c++14 support in /home/$USER/.arduino15/packages/arduino/hardware/avr/1.6.20/platform.txt:
change -std=gnu++11 to -std=gnu++14 in the line starting with compiler.cpp.flags=

TODO

• try some more test patterns
