Hi,
I am working with Arduino Nano 33 BLE. Unfortunately, it looks like the library is not compatible with “mbed_nano” architecture.
Does it make sense to you ?
Do you know what would be the alternative for this type of board ?
Thanks
Sam

Hello,
I am trying to solve an Arduino memory usage issue (Atmega 32u4) and I’m using your library. I notice that there’s a big difference between the results of MEMORY_PRINT_FREERAM and FREERAM_PRINT macros. The first one doesn’t seem to correspond to the rest of the results (shown below). Would you be able to tell me why this might be ? Thanks very much for your time !
Free ram :-175 <<result from MEMORY_PRINT_FREERAM
Free Ram Size : 1309 <<result from FREERAM_PRINT+----------------+ 256 (__data_start)

Hello.
You are right, there was a bug solved in the version 2.21.0. You can get it on github, or ask for an update inside the library manager of the IDE.
