Hey Wizards!
I am a newbie in electronics and PCB design. Please forgive me for my silly sounded questions.
I would like to connect the CAN bus, which has an MCP2515 chip, to the Heltec LoRa v2 module. However, as SPI pins are used by the LoRa inside the module, I can’t seem to find the solution for CAN bus comms.
After a bit of research online, I’ve come across a library called “SoftSPI.h”. In the library, there is no mention of the “CS” or “SS”.
Could any of you please enlighten me more about the issue? The above information may not be relevant to what I want to achieve at all as I’m a beginner.
