Documentation for wiring

[kaangoksal]

Can you add documentation on what hardware used? Especially for esp32 demo. I'm trying to make it work with arduino uno and mcp2515, so far couldn't figure it out.

I used this code

#include <SPI.h>
#include <mcp_can.h>

const int SPI_CS_PIN = 10;
MCP_CAN CAN(SPI_CS_PIN);

void setup() {
  Serial.begin(115200);
  
  while (CAN_OK != CAN.begin(MCP_ANY, CAN_1000KBPS, MCP_8MHZ)) {
    Serial.println("CAN BUS initialization failed, retrying...");
    delay(100);
  }
  Serial.println("CAN BUS initialized successfully");
}

void sendCanMessage(byte* data, int length) {
  CAN.sendMsgBuf(0x070, 0, length, data);
  delay(10); // Small delay to ensure message is sent
}

void loop() {

  Serial.println("Sending commands");
  // Enter "AT command mode"
  byte atCommand[] = {0x41, 0x54, 0x2b, 0x41, 0x54, 0x0d, 0x0a};
  sendCanMessage(atCommand, sizeof(atCommand));
  delay(100); // Wait for command to be processed

  Serial.println("Switched to at mode!");
  // Rotate the motor forward for 1 second
  byte forwardCommand[] = {0x41, 0x54, 0x90, 0x07, 0xeb, 0xfc, 0x08, 0x05, 0x70, 0x00, 0x00, 0x07, 0x01, 0x95, 0x54, 0x0d, 0x0a};
  sendCanMessage(forwardCommand, sizeof(forwardCommand));
  delay(1000);

  // Stop the motor for 1 second
  byte stopCommand[] = {0x41, 0x54, 0x90, 0x07, 0xeb, 0xfc, 0x08, 0x05, 0x70, 0x00, 0x00, 0x07, 0x00, 0x7f, 0xff, 0x0d, 0x0a};
  sendCanMessage(stopCommand, sizeof(stopCommand));
  delay(1000);

  // Rotate the motor backward for 1 second
  byte backwardCommand[] = {0x41, 0x54, 0x90, 0x07, 0xeb, 0xfc, 0x08, 0x05, 0x70, 0x00, 0x00, 0x07, 0x01, 0x6a, 0xaa, 0x0d, 0x0a};
  sendCanMessage(backwardCommand, sizeof(backwardCommand));
  delay(1000);

  // Stop the motor for 1 second
  sendCanMessage(stopCommand, sizeof(stopCommand));
  delay(1000);

  // Wait before repeating the sequence
  delay(5000);
}
