Single Pair Ethernet (SPE) sind mehrere neue Ethernet Standards, bei denen die Kommunikation über nur ein einzelnes Adernpaar funktioniert. Embedded Linux ist dabei gerade auch für kleinste, über SPE angebundene Knoten bestens geeignet. Pengutronix ist dieses Jahr Partner des Single Pair Ethernet Forums in Ludwigsburg und trägt darüber hinaus einen Vortrag bei.
LXA USB-T1L ❤️ Beagle Play: Exploring Single Wire Ethernet
It seems everybody is talking about Single Pair Ethernet (SPE) these days. So we want to follow the trend and do the same :-) SPE is a class of Ethernet transmission standards that uses just a single pair of twisted pair cable for data transmission. There are multiple SPE variants spanning maximum data rates from a hand full MBit/s to multiple GBit/s and cable lengths from a hand full of meters to kilometers. The most interesting ones from our embedded-centric point of view are 10Base-T1L (point-to-point, up to 1 km), 10Base-T1S (multidrop, approx. 10 m) and 100Base-T1 (point-to-point, 15 m). The new Beagle Play comes with a 10Base-T1L PHY. This makes it a great peer to experiment with our Linux Automation USB-T1L. In this post we will explore the possibilities of 10Base-T1L on a recent Linux system.
