Trying to do a quick project with (Wemos) Lolin s2 Mini
Having problems with libraries wanting to use USBSerial and not finding it. In fact, just including arduino.h throws these errors.

platformio:

Code: Select all

[env:lolin_s2_mini]
platform = espressif32
board = lolin_s2_mini
framework = espidf, arduino
monitor_speed = 115200
lib_ldf_mode = deep

Code:

Code: Select all

#include <Arduino.h>

void setup() {
  Serial.begin(115200);
  while(!Serial){}
}

void loop() {
   printf("Hello World\n");
   Serial.println("Serial.println Hello World");
}

sdkconfig includes

Code: Select all

CONFIG_AUTOSTART_ARDUINO=y

Output...

And to prove the point... this code:

Code: Select all

#include <Arduino.h>

void setup() {
}

void loop() {
}

throws similar errors...

Somebody mess up arduino.h for this chip??

[PeteDD]

Anybody???

Still no one has an idea on this?
