TMC2130 is a high-performance two-phase stepper motor driver chip with a standard SPI interface and a simple step/dir interface. The continuous output current is up to 1.2A, and it can withstand a peak current of 2A in a short period of time, with extremely low noise, and high load driving without losing steps.
The SPI working mode of TMC2130-V1.1 can directly select the drive current, drive subdivision, and other parameters through the firmware, making these parameters more accurate; the use of an external sequencer greatly reduces the workload of the chip and effectively avoids the overload of the chip due to the workload. Problems caused by deviations, lost steps, faults, etc.
Drive current algorithm and adjustment
1. Vref measures the voltage between GND and the potentiometer.
2. When measuring the voltage, the power supply should be turned on. Don't just connect the USB power supply.
3. When measuring voltage, be sure not to connect the motor, otherwise, the drive will be burnt easily.
4. Drive current algorithm: i-Vref*1.9/2.5, the default Vref is about 1V, so the default current is 0.76A, and the maximum current is 2A! Please pay special attention to the direction and do not plug it in reverse!
