Compile error- no matching function for call to 'min(unsigned int, const uint32_t&)'

[agrieco]

I'm fairly new to arduino and am trying to get this code compiled and loaded on a NodeMCU (ESP32-S). I'm getting this error and can't seem to figure out what is going on. Any help would be appreciated

thanks

hio, i have downgrade my board library for the esp32 from v3.0 to v2.0.17 and now it runs.

Thank you for your solution. I had exactly the same error message when compiling and was able to fix it by downgrading the library for the esp32 from v3.0 to v2.0.17.
