How to connect MCP 2515 to a 8266 board?

[faspie]

Hi, meanwhile I got it managed to install a binary of your fw to a 8266 board. However there is still no connection to the can bus. Is there a wiring diagram available how to connect the 8266 board to the mcp2515 can module?

You need to find that out yourself for your setup. The MC2515 is connected via SPI, you must configure the pins on 8266, and it should work. There are examples on the internet..

OK, meanwhile I got it working. I think you have done a very good work in programming but your how-to is very bad for newbies. I would suggest I will my buderus 4000 get working an then I would send you a readme for dummies with pictures and detailed informations. Is this OK?

And again: Thank you for your effort!!!

Could you post a few pictures of how you connected the MCP2515?

Sorry for delayed answer. Here are the pictures. At the moment I am too busy for writing a howto.

CANboard	ESP8266
========	=======
INT	->	D1 (GPIO5)
SCK	->	D5 (GPIO14)
SI	->	D7 (GPIO13)
SO	->	D6 (GPIO12)
CS	->	D8 (GPIO15)
GND	->	GND
VCC	->	3V3

Eco-Bus		Function
=======		========
1	->	GND (cable shield)
2	->	CanL
3	->	CanH

This works for me
