![]() Compared to UART and I2C, it is the fastest. SPI operates at full-duplex where data can be sent and received simultaneously. ) I am a beginner in electronics so i request you to a bit detailed. SPI, which stands for the serial peripheral interface, is similar to I2C where it is a different form of serial-communications protocol specially designed for microcontrollers to connect. I am using an eleksmaker mana 3 axis board as a controller. so how do i connect those two PWM pins to the microchip to eleminate the pot on the motor driver board and control it digitally. ) But the problem is the driver board uses a 10K pot, and my cnc controller board gives out PWM singal via only two pins i.e +10V and GND. Driver specs: Working Voltage: DC 10-50V Output Voltage: Linearity Under Load Maximum Current: 60A Persistent Current: 40A Fixed frequency: 25Khz Speed Control Range: 0%~100% Speed Regulation Method: Potentiometer (Tape Switch) Speed Control Type: Regulating Current Forward Reversal: Support Support Motor: DC Brush Motor (Driver board link. I will be using a motor driver to control the spindle motor. I am using a brushless dc motor as a spindle ( Motor specs. */ #include byte address=0x11 int CS= 10 void setup() Video : modified by By Mohannad Rawashdeh This code used to control the digital potentiometer MCP41100 connected to arduino Board CS > D10 SCLK > D13 DI > D11 PA0 TO VCC PBO TO GND PW0 TO led with resistor 100ohm.
