I just love how easy it is to control stepper motors with this driver and a Arduino. using the goHome function and getPos really helps. However, it’s worth noting that the AutoDriver library is configured for Arduino Uno and other Arduino boards that uses SPI on pin 10, 11 and so on. When using a Arduino Mega, you can go to AutoDriver.cpp and change the hardcoded pins in the SPI config function to 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS).
but couldn’t it be possible to daisy-chain the autodrivers, requiring only one SS pin? But thanks for the pointers! However, we’re only using twelve stepper motors - so I hope we can do it with a Arduino Yún (if it’s possible to daisy-chain)
Quick question (I hope). Is it possible to connect 12 of these, each with a 2A (NEMA 23 size) stepper onto a single Arduino board? E.g. Arduino Mega, since I guess you need one select pin pr. autodriver board (12 pins excl. the SPI ones)? and a +24Amp power supply running it?
No public wish lists :(
