说明
- Application Circuit for one Stepper using PCA9538 with 2-Position Sensors. The PCA9538 GPIO used to have an I2C slave address = 0x40 by connecting both the address pins A0 and A1 to ground. The push-pull IO4, IO5, IO6 and IO7 are configured as output pins using the Configuration register. These pins are connected to G1 through G4, the gates of MOSFETs to drive the motor coils. The maximum I2C-bus speed supported by PCA9538 is 400 kHz
