Invert HSPICS on SPI1

Postby RFZ » Mon Aug 21, 2017 1:26 am

Hi,
short question ;)
Is there a setting/register bit for the ESPs SPI1 hardware to invert the CS signal on GPIO15 / HSPICS? I need it to be HIGH during data transfer.
Thx

The setting is not available in HSPI registers. I guess you will need an external inverter or just use a GPIO for slave selection. Hopefully you don't need to change the CS signal too often.
