Please add Wemos Lolin S3

[davy39]

Hello, I've just purchased a Lolin S3 which has been added on arduino-esp32. Could someone add this board to platformio please ? Thanks by advance !

I don't know if it's optimal since I'm a newbie, but I've created the following json that seems pretty functional. Could someone tell me if I'm missing something ?

maximum_size is wrong. For 16MB it is 16777216

[davy39]

I didn't understand neither... But I took same parameter than in Wemos PR here. Do you think this is a mistake ?

[Jason2866]

Yes, it is wrong in the Arduino PR from Wemos. This is useless

"-DARDUINO_RUNNING_CORE=1",
"-DARDUINO_EVENT_RUNNING_CORE=1"

since this is defined (set already) at compile time in the Arduino lib Builder. and is in sdkconfig.h which is included in every Arduino build. The variables are read only. I know many boards.json does have this entrys. It does no harm, but it is litter...

[davy39]

Thanks for your replies, I've modified my json. Shall I open a PR ?

[Jason2866]

Good idea
