Re: i2c randombly fails

So these two still true?
  • The done bit on an end command never gets set
  • A read or write cannot directly follow an end command.

Re: i2c randombly fails

So the other three issues you mention are still unresolved, your driver just works around them?

I am sure dataratesa is same.I don't understand what is "the on air times".The experimental environment is in the air.


The time the radio is transmitting. If lower txpower may be more retries or slower bitrates.

You mean rounded up to the nearest 4 byte boundary?

Re: [Question]: Maximum interrupt rate on GPIO

I know you are just experimenting but no harm to add this reference here for others

ESP32 I2S supports a camera slave mode for high-speed data transfer from external camera modules.
