I did not, it looks like a bug/limitation in IDF or hardware. I am using two separate reads as a workaround for the time being.

This was the first thing that I tried. It does not work and times out similarly to using two command links. Logic analyzer shows that it gets stuck after reading the first byte.

Thank you, but a multi byte read from a single register is not what I need. I need two single byte reads from two registers without a stop signal in between.
MAX44009 IC will not autoincrement the register if I read several bytes in a row.

Hi all, I have been trying to use MAX44009 light sensor, it stores the illumination data in two registers and the datasheet specifies that they need to be read one after another without generating a stop signal in between the two reads. Otherwise the two values may be out of sync. I have not figured...
