Can I use I2C interface?

Hi,
I'm using AS3935 with ESP32-S2, but I get a lot of wrong information from the registers when using 3,3V. I read some reports of problems with the I2C interface and saw many projects using SPI.
Did you have problems using I2C and that's why you chose SPI?

Hi diegostf!

No, I started with SPI right away, mainly because all examples I could find were using SPI. It also turned out to be very stable, so I saw no reason to switch to I²C.

I²C is also much slower than SPI, and requires an additional external pull-up resistor on the SCL line.
