<![CDATA[Gateway using Odroid-N2 via 40pin->SPI]]>Hello,

I've made necessary changes to MySensors 2.4.0-alpha in order to work on Odroid-N2 SBC running Ubuntu 21.04 with 5.13.0 kernel
Library would have worked if every reference to pin number was at least uint16_t (not uint8_t, like it is). That's because Odroid-N2 have >2^8 pin numbering, and GPIO ranges in 460-490 decimal.

I've made my fork@github and pushed odroid-n2 required changes version.
Using polling (non-IRQ) mysgw drains 1.0% cpu time.
Still waiting for interrupt issues to resolve with HK team - hopefully soon.

It won't work with kernels >4.9 for Odroid N2, because the developers left GPIO subsystem down (no IRQs, no /dev/gpiomem), and it only works partially...

Thanks.

I got this error:

Could not open /sys/class/gpio/gpio9/direction

i used your github repo. I don't know what is wrong or did i forget something?

i plan to replace RPI 3B and use odroid n2 also via 40 pin SPI bus. Is your library working? Thanks for your work.
