msc example not working? #6

Closed lucadentella closed 3 years ago

lucadentella commented 3 years ago

Hi!

I'm using a lilygo esp32_s2_woor. I was able to run most of the examples provided but the msc one. It compiles but when I connect the module to my PC nothing happens...

I also made an attempt defining this:

#define CFG_EXAMPLE_MSC_READONLY

but it didn't solve. Was anyone able to run this example? Thanks!
