Hi. I’m trying to implement the CAN communication protocol with the ESP32-S3 to read and write the data on the 29-bit extended CAN network. I saw this module called ESP32-S3-CAN from UltraMax on Amazon. Here is the link:
https://www.amazon.co.uk/ULTRAMAX-BOAES ... C67&sr=8-3 That has an on-board SN65HVD232 CAN transceiver. For the software, I’m using Sandeep Mistry’s Arduino CAN library in the Arduino IDE. The code is here
Code: Select all
#include <CAN.h>
#define TX_GPIO_NUM 36
#define RX_GPIO_NUM 35
void setup() {
Serial.begin(115200);
while (!Serial)
;
delay(1000);
CAN.setPins(RX_GPIO_NUM, TX_GPIO_NUM);
if (!CAN.begin(500E3)) {
Serial.println("CAN failed!");
while (1)
;
} else {
Serial.println("CAN Initialized");
}
}
void loop() {
// Send test data on CAN ID 0xEDDF wih Extended 29 bit
CAN.beginExtendedPacket(0xEDDF);
CAN.write(0x90);
CAN.write(0x87);
CAN.write(0x00);
CAN.write(0x00);
CAN.write(0x00);
CAN.endPacket();
Serial.println("done");
delay(1000); //Sending in every 1 sec
}
But the problem is, it is not compiling for the ESP32-S3, and tonnes of errors just popped up when I tried to compile this code. I checked their datasheet, and there is the installation programme for TWAI installation in C. But that is for the ESP-IDF platform and I have not enough knowledge to use ESP32 with ESP-IDF. So, is there any library available for the CAN bus in the Arduino IDE that is the same as Sandeep Mistry’s Arduino CAN for the ESP32-S3? Thanks.
