Does anybood succeed in using the SPI interface on the GPIO pins?

I found some devices on /sys/bus/spi/devices/ named spi0.0 (the rda-dpi-panel) and spi0.1 (the tlv320aic23-spi).
Also the kernel.log shows spi when booting, so in general SPI seems to be enabled in the kernel.

The way the Raspberry Pi is enabling SPI via dtoverlay and dtparm seems not to work with the older 3.10 kernel.

How to make SPI usable for devices connected via GPIO?

Thanks
Achim

You really make it seem so easy with your presentation but I find this topic to be really something that I think I would never understand. It seems too complex and extremely broad for me. I’m looking forward for your next post, I’ll try to get the hang of it! hitamqq

Thanks for the sensible critique. Me and my neighbor were just preparing to do some research about this. We got a grab a book from our area library but I think I learned more from this post. I’m very glad to see such fantastic info being shared freely out there. vn88
