Which it clearly doesn’t! Time to go back to basics. Excuse my bad English! Both Microcontrollers share the same code: That’s a very good post.

SPI problem with MCP2515

If not you can either reverse the bits in software use a byte array or drive the clock and data pins in software. In my example I kcp2515 a reset instruction 0xC0: Email Required, but never shown.

So it looks like nothing is driving it, rather than the possibility of it being shorted to something. Attached Image s 3.


CANSPI Board – Serial CAN Interface with MCP Transciever

Your first instruction should be a Read. Are you shure about it??? This question came from our site for electronics and electrical engineering professionals, students, and enthusiasts. Maybe some examples code would help.

Hope this helps someone else by making sure all the required PINS are terminated before coding: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your sli use of the website is subject to these policies.

I have tried numerous initialization sequences with no success. I’m all for reading documentation, but I agree this is definitely obscure.


Let me quickly cut the track of PB2 and connect a botch wire to PB0 to test it. Please see the datasheet of MCP below for your reference. Looking at your trace I can see you are sending “”.

avr – Getting no response from MCP using SPI – Electrical Engineering Stack Exchange

I have verified the connections by using a voltmeter continuity test, I have verified the ground and voltage connections to the IC. DAC input digital signals, how to generate?

Thank you Tom for your answer. In the library defaults I can see: I have a board with a working SPI interface.
