HSPI chip select
Posted: Sun Aug 20, 2017 4:53 pm
Hi,
I searched the board an the source for uP ESP2866 edition, but didn't find anything related to this.
According to the documentation of my ESP2866 12E, GPIO15 should be SPI 1 chip select.
However it does not toggle when I transfer data (as verified by my scope). MOSI and CLK work just fine.
The driver source seems to be here:
https://github.com/micropython/micropyt ... spi.c#L100
The comment is a bit cryptic for me to understand. So I guess the bottom line is: can the hardware CS be activated, or do I have to emulate it myself?
