原创 STM32 CAN波特率计算
最近一个项目需要用到STM32芯片的CAN接口,在网上搜了一下计算波特率的软件,发现没有找到合适的,就用QT自己做了一个,方便自己找出合适的SJW,BS1,BS2,BRP组合,感觉效果还不错,就分享出来,有需要的可以下载。...

STM32_CAN波特率计算.7z
采用QT编写的STM32系列的CAN总线波特率计算器,输入指定的系统频率,需求的波特率,以及指定各种条件,计算出所有符合条件的SJW,BS1,BS2,BRP的值组合,并且对符合CIA建议的采样率组合行进行标红置前处理。

88E6085.pdf
Marvell的8口以太网交换芯片88E6085的datasheet文档。
The Marvell® 88E6085 device is a single chip integrated 10-port Fast Ethernet switch. This device supports ‘Best-in-Class’ Quality of Service (QoS) and the
highest ‘real-world’ performance. It is uniquely
designed for SOHO router and gateway applications.
This device contains eight 10BASE-T/100BASE-TX
transceivers (PHYs) and two MII ports. The 88E6085
device is designed to work in all environments. True
Plug-and-Play is supported with Auto-Crossover,
Auto-Negotiation, and Auto-Polarity in the PHYs,
along with bridge loop prevention (using Port States).
The 88E6085 contains ten independent 802.3 media
access controllers (MACs), a high-speed, non-blocking four traffic class QoS switch fabric that uses the
unique patented Marvell Dynamic Queue Limit architecture. The QoS architecture switches packets into
one of four traffic class queues based upon Port, IEEE
802.1p, IPv4 Type of Service (TOS) or Differentiated
Services (Diff-Serv), IPv6 Traffic Class, 802.1Q VLAN
ID, DA MAC address or SA MAC address. The
devices also contain a high-performance address
lookup engine with support for up to 2K active nodes,
and a 1 Mbit frame buffer memory. Back-pressure and
Pause frame-based flow control schemes are included
to support zero packet loss under temporary traffic
congestion. The MAC units in the devices comply fully
with the applicable sections of IEEE 802.3.
The two MII interfaces support a direct connection to
Management or Router CPUs with integrated MACs.
Both interfaces support MII-PHY mode or MII-MAC
mode. These interfaces, along with BPDU handling for
IEEE 802.1D Spanning Tree Protocol, 802.1w Rapid
Spanning Tree, 802.1s Multiple VLAN Spanning Tree,
programmable per-port VLAN configurations, 802.1Q
and Port States, support fully managed switches and
truly isolated WAN vs. LAN firewall applications. The
device supports 64 802.1Q VLAN IDs which can be
enabled on a per port basis. Three levels of 80
