Gaston - Hi all,I am trying to build the sense...
Hi all,
I am trying to build the sense_template code for a lolin_s2_mini (Wemos S2 mini). I get build errors. The only thing I changed is the
[env] settings in the platformio file.
The error is related to the LED_BUILTIN = 15; code (see image).
Is there anyone that can help me out here? My coding experience is limited.

can you share your current platformio.ini? i suspect the problem might be in there..
; PlatformIO Project Configuration File
;
; Build options: build flags, source filter
; Upload options: custom upload port, speed and extra flags
; Library options: dependencies, extra library storages
; Advanced options: extra scripting

static const uint8_t LED_BUILTIN = 15;
^~~~~~~~~~~
And more messages regarding the same error.My 2cnt: You're declaring
LED_BUILTIN both as a macro in your build_flags and defining a const which creates a conflict?yeah, i thought the same..
try changing
-D LED_BUILTIN=2
to
; -D LED_BUILTIN=2
and check if that fixes itThat did indeed work. Thank you.
