3.1.5 Test Points (in addition to ESELSBRÜCKE)
Apart from ESELSBRÜCKE the evaluation system provides test points on the TMC5130-EVAL.
TEST POINTS ON TMC5130-EVAL
Label Description
R_SENSE1
Sense resistor motor coil A
R_SENSE2
Sense resistor motor coil B
GND
Signal and system ground
AIN_REF Analog reference voltage of AIN_REF_SW (internal current sensing) or of AIN_REF_PWM
(analog current scaling using microcontroller PWM).
REFL_STEP
Left reference input or STEP input (depends on settings of SD_MODE and SPI_MODE
bits). Note that this test point is directly connected to the TMC5130.
REFR_DIR
Right reference input or DIR input (depends on settings of SD_MODE and SPI_MODE
bits). Note that this test point is directly connected to the TMC5130.
