STNucleo: MCP2515 CAN BUS Transceiver tutorial for STM32 (Communication with Arduino)

The MCP2515 CAN Bus Transceiver is typically used with microcontrollers such as STM32, aTMega (arduino), etc. because of its SPI interface. It allows communication via the CAN protocol, thus reading and writing to any CAN Bus. Using the MCP2515 is very easy thanks to the considerable amount of documentation and code available, including regarding the use of the SPI protocol.
Using it on STM32 is already more complicated, as the pin capabilities of this microcontroller are very flexible and therefore implementation is left to the programmer. For us this is not a problem, we will take existing code written for STM32 and go and adapt it to our needs, thus enabling the STM32 to communicate in CAN Bus.
Of course you can take advantage of this module to sniff packets passing over the CAN Bus of your car.

Complimenti per il video, come al solito ben fatto e con professionalità. Ottimo!

[@carnivorah8837]

You're a livesaver, thanks man! Also, whoever added Russian subtitles, I would kiss you!

[@michaelkosciewicz1623]

Abbisale è la scoperta del tuo canale, per la necessità di questo progetto... Forte

[@Juan123qwerty]

Greetings from Mexico

[@anujpatel6438]

nice one

[@RyanJrOfficial210]

i work on stm32f103c8t6 and configure every pin like you. But when debug to this line there is nothing happen to return true. Can you tell me why ?

[@yaakoubinawres1043]

Can i communicate stm32 with raspberry pi using mcp2515

[@joeltshiela4605]

👍👍 merci

[@luisfernandoalvarez5500]

Mil Gracias. He estado trabajando con la red ESP NOW con los ESP-32 y ESP-8266. yA LA HAS TRABAJADO?. Necesito observar cuándo una variable análoga ha cambiado(como la de un potenciómetro. Me ayudas con eso en el IDE de Arduino?. Un abrazo desde Colombia.

[@blisca]

Grazie,spieghi molto bene. Non ho mai fatto nulla con CAN bus.Diversi microcontrollori hanno già un modulo CAN,in quel caso questa interfaccia sarebbe ridondante e sarebbe meglio usare qualcosa che si occupa solo del livello elettrico?

[@edinetgrunhed6000]

any hardware modification for CAN Transceiver? If this video in English more people will understand ,very few video of CAN BUS and STM32

[@jorgeluismadridgomez1643]

Hello, one question ¿How can we define the CAN velocity and MCP clock freq as we can do it in arduino with mcp2515.setBitrate(CAN_1000KBPS, MCP_8MHZ)?

[@OrangeBomb94]

You can change this strings to this MCP2515_WriteByte(MCP2515_CNF1, 0x00); MCP2515_WriteByte(MCP2515_CNF2, 0x90); MCP2515_WriteByte(MCP2515_CNF3, 0x82);

[@mudarris1031]

Hy. can you make tutorual video send pwm value with Controller Area Network (CAN) in stm32 with STM32cubeIDE?

[@alessandroromanini7696]

Ciao Deniel , spieghi benissimo complimenti . potresti fare qualche video per interfacciarsi con le schede ethernet?

[@ProjectoOfficial]

Certo! purtroppo però non ho una shield ethernet, spero di riuscire a reperirla al più presto, ormai i componenti embedded iniziano ad essere molto rari su amazon rispetto a qualche anno fa
