Serial2 Don't compile

[ardisd]

I have recently changed to using https://dl.espressif.com/dl/package_esp32_index.json in the boards manager now any application using serial2 wont comple. I get an error Error compiling for board M5Stack-Core-ESP32.

Thanks

@ardisd Can you post a screenshot of the error ouput from arduino?

[ardisd]

Enclosed screen shot as requested

I get the same error when compiling Serial2.ino and my own code

[ajb2k3]

Are you running arduino 1.8.7?
Thats not all the error.

[ardisd]

Upgraded to 1.8.7 was on 1.8.5

This is the error now

I first thought is to tell you to Backup and delete the SD folders in dropbox and
C:\programfiles(x86)\Arduino\Librarys\SD
and then try again.

Can I see your source code?

Just the standard serial2 sketch

#include <M5Stack.h>

HardwareSerial Serial2(2);

void setup() {

M5.begin();

Serial.begin(115200);

// Serial2.begin(unsigned long baud, uint32_t config, int8_t rxPin, int8_t txPin, bool invert)
Serial2.begin(115200, SERIAL_8N1, 16, 17);
}

void loop() {

if(Serial.available()) {
int ch = Serial.read();
Serial2.write(ch);
}

if(Serial2.available()) {
int ch = Serial2.read();
Serial.write(ch);
}
}

I got the same problem.
I changed the rename of Serial2 and fixed it.

HardwareSerial Serial2(2);
→HardwareSerial Serial2_(2);

@nnn 在 Serial2 Don't compile 中说：

HardwareSerial Serial2_(2)

Thanks

That worked for me
