Connect Microcontroller
Steps for connecting a 32-bit microcontroller (such as Teensy, Raspberry PICO, Arduino Due, or ESP32) to the BLDC driver board
BLDC driver board with 3-Phase motor driver (L6234D) and magnetic encoder (AS5048A or AS5047)
Not all driver boards have current sensors
Motor driver | MCU |
|---|---|
GND | external power source (-) |
VDD | external power source (+) |
EN | digital pin |
IN1, IN2, IN3 | PWM enabled digital pins |
C1, C2 | analog (ADC) pins |
Encoder | MCU |
|---|---|
V3.3 | 3.3 volt output |
GND | ground pin |
CS (select) | CS/SS pin (Teensy 3.2: PIN10) |
SCK (clock) | SCK/SCLK/CLK pin (Teensy 3.2: PIN13) |
MISO (master input, slave output) | MISO/SDI/DI/DIN pin (Teensy 3.2: PIN12) |
MOSI (master output, slave input) | MOSI/SDO/DO/DOUT (Teensy 3.2: PIN11) |
/* CS pin of the encoder */
#define CS_MAGNETIC_SENSOR_PIN 10
/* BLDCMotor (int pole-pairs): GB36-2 has 7 pole-pairs */
BLDCMotor _bldc = BLDCMotor(7);
/* BLDCDriver3PWM(IN1, IN2, IN3, EN) */
BLDCDriver3PWM _driver = BLDCDriver3PWM(21, 22, 23, 20);
