Hello, thank you for your awesome app! I love it
the project I’m working on is getting data from pins and logging the using (insert into) in mySQL
this is a draft code because I’m using temp as a placeholder for what I want
I get this error
Exception (3):
epc1=0x402064c2 epc2=0x00000000 epc3=0x00000000 excvaddr=0x40232a24 depc=0x00000000
I have commented the execute out because I just want to see the value for now, but I want that to work too

Thank you for your help!
