Problem with SRK25ZJX-S

[makonrus]

Please create a log with time stamp and some more entries before and after the effect. In addition, how does row 30 of MHI-AC-Ctrl-core.h
//#define POWERON_WHEN_CHANGING_MODE true
looks like?, Unchanged or have you commented it in?

I just commented this line and the problems with switching modes disappeared. But if this line is not commented, then the problem remains.

There should be 4 different fan speeds, no auto mode for the fan.

My remote control has 3 speeds and Auto mode:

We've seen this instability alrady e.g. in the issue10. I couldn't find out the root cause, but since this seems to be not critical, I postponed it. btw: If you have an oscilloscope, a measurement would be helpful.

Yes, I have an oscilloscope, but I can connect it to the AC no earlier than next week.

Here is the test program log:

In addition, how does row 30 of MHI-AC-Ctrl-core.h
//#define POWERON_WHEN_CHANGING_MODE true
looks like?, Unchanged or have you commented it in?

I just commented this line and the problems with switching modes disappeared. But if this line is not commented, then the problem remains.

I believe the bug is in row 137 of MHI-AC-Ctrl-core.cpp. Please replace
MISO_frame[DB0] |= 0x11;
by
MISO_frame[DB0] |= 0b11;
and try it again. Will come back to you for the other topics.

There should be 4 different fan speeds, no auto mode for the fan.

My remote control has 3 speeds and Auto mode:
http://splitoff.ru/wp-content/uploads/pults/ESC-RC-195.jpg

The IR remote control supports Fan level 1 ... 4 and 'auto'. Unfortunately Fan 'auto' is not supported via a SPI remote control.

Yes! Now everything works fine.

The IR remote control supports Fan level 1 ... 4 and 'auto'. Unfortunately Fan 'auto' is not supported via a SPI remote control.

That is, the Auto fan mode and the vanes position switching mode are not sent by the AC to the SPI bus? It would be necessary to check by oscilloscope.

I just uploaded a SPI logger. Please use it for creating another log.
