Thank you for you reply. I was looking for an ADC chip and the ones I can source locally are all SPI devices. Since I really do not need accuracy, I redid my design to use analog data multiplexors and comparators driver by gpio pins.
To use an ADC I would probably need an SPI driver and then a driver for the ADC device. -----Original Message----- From: owner-...@openbsd.org <owner-...@openbsd.org> On Behalf Of Mark Kettenis Sent: May 17, 2018 5:22 AM To: s_g...@telus.net Cc: arm@openbsd.org Subject: Re: spi interface > From: <s_g...@telus.net> > Date: Tue, 15 May 2018 14:32:16 -0700 > > Is there a working spi interface for Allwinner H3? I don't think there is any SPI support in OpenBSD at the moment. What are you trying to achive?
