TMC2209 stepper driver module tutorial

My first stepper driver module was A4988 and recently I have decided to give TMC2209 a try hearing how silent and energy efficient it is. Driving the A4988 is simple - just set direction, pulse the step pin and the motor moves. You can do the same thing with TMC2209 but this thing can do much more. It has UART interface, registers, algorithms and an 83 pages datasheet. I might be slow but I had to read the datasheet 3 times to wrap my head around on what things can this thing do. In my opinion it is a very good stepper driver so I made a library for it and also this tutorial to better help in using the library. Although the IC presented in this tutorial is TMC2209, most information can still be applied to other TMC ICs.

TMC2209 description

The TMC2209 is an ultra-silent motor driver IC for two phase stepper motors, developed by trinamic. TMC2209 pinning is compatible to other drivers as well as to the TMC2208.

Multiple versions of modules can be found that are using this IC, however the stand-alone chip can be used for a DIY module that could provide some cost savings.

Features:

  • 2-phase stepper motors up to 2.8A coil current (peak), 2A RMS
  • STEP/DIR Interface with 8, 16, 32 or 64 microstep pin setting
  • Smooth Running 256 microsteps by MicroPlyer™ interpolation
  • StealthChop2™ silent motor operation
  • SpreadCycle™ highly dynamic motor control chopper
  • StallGuard4™ load and stall detection for StealthChop
  • CoolStep™ current control for energy savings up to 75%
  • Low RDSon, Low Heat-Up LS 170mΩ & HS 170mΩ (typ. at 25°C)
  • Voltage Range 4.75… 29V DC
  • Internal Sense Resistor option (no sense resistors required)
  • Passive Braking, Freewheeling, and automatic power down
  • Single Wire UART & OTP for advanced configuration options
  • Integrated Pulse Generator for standalone motion

How to use A4988 stepper motor driver module tutorial

A4988 stepper motor driver module

This driver can be used to easily control a bipolar stepper motor or a uni-polar stepper connected in a bipolar mode. Can output up to 2A per phase (with a heatsink) and works with motor voltages from 8 to 35 volts.

  • Simple step and direction control interface
  • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
  • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
  • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
  • Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
  • Short-to-ground and shorted-load protection
