Strange Error on Nextion

Hi everyone,

I’m developping an open source tesla coil controller using a Nextion 5" basic model and a Cortex M4 based microcontroller from TI. Today a user of this controller reported that it crashed (details in this post and the following ones).
I’m not sure what’s the origin of the crash (possibly EMI) but I do know I’ve never seen the error displayed on the Nextion screen.

Can anyone tell me more about this…?

Thank you very much!

Here’s the actual error screen: “recursive depth exceeds the maximum value!”
