Returns

None

Examples

#include <CANBus.h>
unsigned char buf[8] = {0, 1, 2, 3, 4, 5, 6, 7};
 
void setup() {
    Serial.begin(115200);
    CAN.begin(CAN_500KBPS); // Configure CAN bus transmission speed to 500KBPS
}
 
void loop() {
    CAN.beginTransmission(0x00, CAN_STDID);    // Set the CAN device ID to 0x00, using standard data grame.
    CAN.write(buf, 8);                         // Sent 8 bytes of data
    CAN.endTransmission();                     // End transmission
    delay(10);
