Posted on December 04, 2017 at 09:10 Hello everybody,
Since the release of the new documentation (Datasheet V5 and Command Guide V2), I'm looking for more detailed informations about SPI interface, SPI timing and SPI dialogue.... but the new doc is still poor in informations about SPI (really poor).
After lot of trial, I could send a SOCKDW on my SPI:
02 00 0F 4A 03 01 00 01 00 01 07 AA AA 03 DF 01 01 1F
It means : SOCKDW, sid=0, cid=0, len=7, data isAA AA 03 DF 01 01 1F
After that, I receive the two following reply from SPWF04SA:
02 3A 00 00 00
which I think is a'OK result code' as mention in Command Guide page 14 (see chapter 6.1)
and
02 3A 21 00 00
which I don't know what it is.... because it is not documented....
So my question is double :
Could we have a proper documentation about the SPI interface (sync reply, dialogue sample, )?
and
What does the '02 3A 21 00 00' means?
PS: I really appreciate the new example for SPI protocol but the Second example has still its length false and the text about the translate procedure still contains wrong informations about the byte number.

[EDIT 2018] I add a SOCKDW example
#sockdw #spi #spwf04
