ESP32C3 Compilation Error

[peppeve]

I get this error compiling the message sender example.

c:\Users\User\Documents\Arduino\libraries\NMEA2000_esp32\NMEA2000_esp32.cpp:33:10: fatal error: soc/dport_reg.h: No such file or directory
33 | #include "soc/dport_reg.h"

Compilation error: exit status 1

The ESP32C3 supports a two-wire automotive interface (TWAI), which is compatible with ISO11898-1 classical frames CAN 2.0

NMEA2000_esp32 is not compatible with esp32c3, you may try
https://github.com/jiauka/NMEA2000_esp32xx

[peppeve]

#include <NMEA2000_esp32xx.h>

but i get same error.

fatal error: soc/dport_reg.h: No such file or directory
33 | #include "soc/dport_reg.h"

You have to disable NMEA2000_ESP32

and modifying

NMEA2000-library/src/NMEA2000_CAN.h

For 32xx naming

#elif USE_N2K_CAN == USE_N2K_ESP32_CAN #include <NMEA2000_esp32xx.h> // https://github.com/ttlappalainen/NMEA2000_esp32 tNMEA2000 &NMEA2000=*(new tNMEA2000_esp32xx());

[peppeve]

Already done, modified nmea2000_can.h

//#elif USE_N2K_CAN == USE_N2K_ESP32_CAN
//#include <NMEA2000_esp32.h> // https://github.com/ttlappalainen/NMEA2000_esp32
//tNMEA2000 &NMEA2000=*(new tNMEA2000_esp32());

#elif USE_N2K_CAN == USE_N2K_ESP32_CAN
#include <NMEA2000_esp32xx.h> // https://github.com/ttlappalainen/NMEA2000_esp32
tNMEA2000 &NMEA2000=*(new tNMEA2000_esp32xx());

but i get this error:

Which Arduino version are you using?

[ttlappalainen]

You do not need to modify NMEA2000_CAN.h. Just do not include it. Instead define what you want to use and create NMEA2000 object.

...
#include "N2kMsg.h"
#include "NMEA2000.h"
#include <NMEA2000_esp32xx.h>
#include <N2kMessages.h>

tNMEA2000 &NMEA2000=*(new tNMEA2000_esp32xx());
...

Above does not help for you last error. It is related to Arduino version you use.

Note that NMEA2000_esp32xx.h does not use properly NMEA2000 library features, so it will not be added to NMEA2000_CAN.h, which is easy for beginners and for testing, if you use same code for different MCU:s

I'm using Arduino IDE 2.3.2

Any help will be appreciated

Solved with updated version of the NMEA2000_esp32xx library
