Greetings! Many thanks for this wonderful work!

I'm using ESP32 Wrover and sn65hvd230dr and i have this problem: I'm trying to use the esp32can_receive.ino example and it works as expected. But at the same time, when there is no data exchange on the bus, the message TWAI RX: ESP_ERR_TIMEOUT constantly appears in the serial monitor. At the same time, the example itself seems to work fine.

I tried compiling the code using Arduino Release v2.0.15 based on ESP-IDF v4.4.7, as well as Arduino Release v3.0.0 RC1 based on ESP-IDF v5.1, but the problem remains.
Perhaps this is not a problem, but due to the constant loading of the monitor, I do not have time to see the diagnostic messages that I myself send to the serial monitor...

Please help me correct the situation...

There is a typo on send example:

void setup() {
  Serial.begin(115200);
  Serial.println("ESP32-Arduino-CAN Send Basic Demo");

  /* initialize and start, use pin 5 as CAN_tx and pin 4 as CAN_rx, CAN bus is set to 500kbps */
  ESP32Can.CANInit(GPIO_NUM_5, GPIO_NUM_4, ESP32_SPEED_500KBPS);
} 

should be:

void setup() {
  Serial.begin(115200);
  Serial.println("ESP32-Arduino-CAN Send Basic Demo");

  /* initialize and start, use pin 5 as CAN_tx and pin 4 as CAN_rx, CAN bus is set to 500kbps */
  ESP32Can.CANInit(GPIO_NUM_5, GPIO_NUM_4, ESP32CAN_SPEED_500KBPS);
} 

Implement CAN filtering and provide examples.

Esp32 1mbit with this library

if (ESP32CAN_OK == ESP32Can.CANReadFrame(&rx_frame)) { /* only print when CAN message is received*/ processdata(rx_frame); }

Seems as though its not as responsive as the Wagner version. Wagner vers doesnt do 1mbit but it does 500k. 500k is really fast but this one reading at 1mbit seems like there is a small delay somewhere?

Would it be possible to add support for esp32-s3?
