Is it possible to define IF conditions for different boards?
I wanna share the same code for different boards (esp32 & esp8266). These boards need different WiFi libraries. How can I SWITCH them by an IF condition? Is this possible?
I saw, that I can add build params like
But is there something which is set already by PlatformIO?
Yes, as you can see in e.g. here each board has specific macros. But PIO also defines macros like
-DPLATFORMIO=40000 -DARDUINO_Heltec_WIFI_Kit_32 -DESP32 -DESP_PLATFORM -DF_CPU=240000000L -DHAVE_CONFIG_H -DMBEDTLS_CONFIG_FILE=\"mbedtls/esp_config.h\" -DARDUINO=10805 -DARDUINO_ARCH_ESP32 -DARDUINO_VARIANT=\"heltec_wifi_kit_32\" "-DARDUINO_BOARD=\"Heltec WIFI Kit 32\""
(for a heltec esp32 board)
So you could e.g. use
//include ESP32 specific libs
//include esp8266 specific libs
You can do a verbose compilation run with
pio run -v.
