Maybe you could try this lib math, put it in \esp_iot_sdk\lib , and add it in makefile ( esp_iot_sdk\app )

-lc \
-lm \
-lgcc \
-lhal \

libm.zip

Can't read this - can we use functions like log(), sin() etc? I tried including math.h but no joy.

想請問我們需要基本的 round() floor() ceil() 還有 sin() cos() tan() ... 等三角函數運算，在 include 後可以編譯，但是 link 出錯。
round() floor() ceil() 可以自己寫沒問題，不過 sin() cos() 這些就有點頭痛了。
想請問這幾個數學函式要怎麼處理好呢？
