ESP32 Processor: Adding a CAN Bus Transceiver

This post is an excerpt from our application note Controller Area Network (CAN) Development with ESP32.As a quick reference, I want to address the need for a CAN transceiver. As mentioned in the previous chapter, the ESP32 has an internal CAN Bus controller. However, this doesn't mean you can directly connect it to a network. You [...]

Classical CAN (CC), the Original CAN Bus Technology

This post is an excerpt from our application note  Controller Area Network (CAN) Development with ESP32. Note: The term “Classical CAN” was introduced in the ISO 11898-1: 2016 Standard. Classical CAN represents the basis for CAN FD (and CAN XL), meaning they share the same features and advantages, as explained in the previous chapter. While CAN FD adds [...]

CAN FD (Controller Area Network Flexible Data Rate)

This post is an excerpt from our application note  Controller Area Network (CAN) Development with ESP32. CAN FD (Controller Area Network Flexible Data Rate) is an extension of the original CAN bus protocol. It was created to provide increased bandwidth within automotive and industrial networks. It brings application software closer to "real-time" by minimizing delays between instruction [...]
