How to integrate MCP2515 on Raspberry Pi3b+ (Ubuntu 20.04)

au flag

for some time I've been trying to use the Hat RS485 Can based on the MCP2515 chip. Unfortunately, regardless of my attempts, I can only read the frames or send them.

I have loaded kernel modules responsible for can bus communication, userconfig has been modified by adding dtoverlay = mcp2515-can0, oscillator = 12000000, interrupt = 25, spimaxfrequency = 2000000. After setting the parameters ip link set can0 type can bitrate 10000 and ip link set can0 up candump any does not return data present on the bus. However, I can transmit. After adding the listen-only on parameter, of course, I cannot transmit, but the data on the bus is available. Has anyone encountered a similar problem?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
