I want to design a pump station with 12 channels, each channel drive by a stepper motor. And the system, I plan to use STM32F205+L6470, but some issues need help.
1. Can STM32F205 synchronously drive 12pcs L6470 by SPI interface with daisy chain?
2. The CK, CS, SDO, SDI drive capability is enough? If not enough, how to solve?
