Simple question: Why did you remove the temp sensor and LNA sections from the TRM? It's still mentioned in the ESP32 datasheet.
Is there a reason for the removal? I haven't seen any other description of this periferial anywhere else, only in older version of TRM.
There are 2 types of programmer people: The Expert programmer and The Smart programmer

The Expert programmer easily writes any code from scratch.
The Smart programmer uses his google/github powers first ;)

666 pages. This is a perfect example for the saying "The devils in the details" :roll:

Any chance to get the description of following RMT register. That is following member of structure rmt_dev_t in rmt_struct.h?
  1.     uint32_t status_ch[8];                              /*The status for channel0-7*/

That would help to understand the error messages from RMT driver:
  1. E (20119) rmt: RMT[0] ERR
  2. E (20119) rmt: status: 0x14000040
thanks in advance,
gautier

Hi gautier,

Yes, this should be included. rmt_reg.h recently added a description for these bits, but it seems like it wasn't propagated to the rmt_struct.h headers or the TRM. It should be added to both, will chase this up.

In the meantime, you can find the bit descriptions here:
