@dimi 在 Lesson 1.0. Let's start. Hello, MacOS 中说：

#include <m5stack.h>

void setup() {
M5.begin();
M5.Lcd.print ("HELLO, MacOS");

Shouldn't this be #include <M5Stack.h> now (upper case M and S)?

@tomorrow56 I doubt this is still relevant but if you download the M5Burner application from http://m5stack.com/ you can (re-)flash the camera app to the device.
