We build our own custom version of esp32-arduino, in order to get some fixes we've made but haven't yet been merged in master.
|
||
|
|
|
||
|
|
These are a set of currently unformatted notes on how to build and install them. Most developers should not care about this, because
|
||
|
|
you'll automatically get our fixed libraries.
