In_espi min() conflict with sstream

[happyme531]

compile simple code like this:

#include <M5StickC.h>
#include <iostream>
#include <sstream>

void setup() {
  // put your setup code here, to run once:
}
void loop() {
  // put your main code here, to run repeatedly:
}

and get error:

comment the code in In_espi.h, and compiling passes.

#ifndef min
  // Return minimum of two numbers, may already be defined
  #define min(a,b) (((a) < (b)) ? (a) : (b))
#endif

Hello, seems like you figured out the compilation issue by work-around. we don't officially support sstream yet but we will look into it to possibly give better compatibility between the sstream and our framework in the future.

i have the same isssue with the #include < queue > :'(
