Driver component for NMEA2000 library for ESP32 Boards.
To use this library, you will also need NMEA2000 library.
The library defines as default Tx pin to GPIO 16 and Rx pint to GPIO 4. You can change these with defines:
#define ESP32_CAN_TX_PIN GPIO_NUM_5 #define ESP32_CAN_RX_PIN GPIO_NUM_4
before including NMEA2000_CAN.h or NMEA2000_esp32xx.h
A working example can be found at NMEA2000-windesp32xx-idf library
Some tweaks to sdkconfig that are recommended:
CONFIG_TWAI_ERRATA_FIX_BUS_OFF_REC=y CONFIG_TWAI_ERRATA_FIX_TX_INTR_LOST=y CONFIG_TWAI_ERRATA_FIX_RX_FRAME_INVALID=y CONFIG_TWAI_ERRATA_FIX_RX_FIFO_CORRUPT=y CONFIG_FREERTOS_HZ=1000
