I have code which works on an STM32**. The code is the "basic.ino" example from the BSEC github download (dated 5-19-2019) + Tiny ASCII only library for an OLED display.
** by works I mean the Serial monitor printed out the full compliment of measurements and calculations (IAQ etc) from the BME680 and the OLED display functioned properly.
It compiled to 69K for the STM32.
I 've modified the platform.txt for the ESP8266 pretty much the same way the STM32 platform.txt was modified.
Now I'm using a NodeMCU V1 -12E and when I try to compile I continually receive an error: "section `.text1' will not fit in region `iram1_0_seg'"
I'm guessing there are some memory boundries on the NodeMCU but except for knowing the term "Memory boundry" I'm lost.
It seems others have this software on the ESP platform so I'm assuming its something I did or didnot do. Any suggestions would be appreciated.
