특징
- Silent Step 4 Click is a compact add-on board representing a completely integrated step motor driver solution. This board features the TMC2240, a smart integrated stepper driver from Analog Devices. The driver is based on a 256 micro-steps built-in indexer, two fully integrated H-Bridges, and non-dissipative integrated current sensing (ICS). The two H-Bridges can drive motors of up to 36V and 3A at max. This Click board™ makes the perfect solution for the development of textile industry machines, lab and factory automation, 3D printers, and more..

HOW DOES IT WORK?
Silent Step 4 Click is based on the TMC2240, a smart integrated stepper driver from Analog Devices. It is highly integrated and highly efficient with a best-in-class performance stepper driver. The maximum output current per H-Bridge is 3A, which an onboard resistor sets. You can, however, set it to a lower level over the software. The step driver also features abundant diagnostics and protections such as short protection/OCP, thermal shutdown, and under-voltage lockout. It can measure the driver temperature, estimate the motor temperature, and more.
One cool feature is the rotary encoder interface integration directly into the step driver. The external incremental encoder can be connected over the ENC connector. The encoder can be used for consistency checks on the fly between the encoder position and the external ramp generator position. A 32-bit encoder counter is provided. StallGuard2 is a great functionality for detecting a motor stall and is part of the diagnostic system of the stepper driver.
Silent Step 4 Click uses a 4-wire SPI serial interface to communicate with the host MCU, supporting a max frequency of up to 10MHz. The motor is controlled using step and direction inputs over the STP and DIR pins. Each step can be a full-step or a micro-step. The additional functionalities are provided over the PCA9538, an 8-bit I/O port from NXP. The PCA9538 uses an I2C interface to communicate with the host MCU. The I2C address can be set over the ADDR SEL jumpers. It provides monitoring of both DIAG outputs and over-voltage indicators. It also controls the enable and sleep inputs of the stepper driver. The host MCU can reset the PCA9538 over the RST pin and receive interrupts over the INT pin.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
