wizardb101•5/4/24, 7:09 PM

Esp8266 is a good module, though esp32 is a upgraded version
Pinouts are easily accessible on web, you can refer from that
Regarding the speed, it only uses wifi so should be fine if you are working on a small prototype or something. But if you want to implement you have to test it with better modules
Esp8266 are essentially made for prototyping and in very few cases it is used properly in a product. Also they tend to heat up after some use or some boards tend to fry, if not used correctly so make sure that you check the documentation once to be sure
And keep some extra esps

Can anyone help explain the step-wise procedure for sending data using the CAN protocol?

I'm working on Project Where we are Calculating the Distance using Ultrasonic sensor and wanted to send the data using CAN Protocol ,

I'm Using Controller Board STM32F407 DISCOVERY BOARD 1 , I'm Using the CAN Module for Communication, Module : CAN transceiver SN65HVD230

1) I wanted to send data using can Protocol , Can any one explain in detail and Step wise procedure for send the data over CAN ?

2) Suppose There are Multiple Sensor are Connected to CAN bus, Multiple Sensors Sending Data, Through The CAN , to The microcontroller how to read data of a Perticular Sensor, throughout the CAN ,and use that data in other task , explain step wise process?

Navadeep•5/5/24, 6:18 PM

1) You can use the APIs provided by ST for this https://controllerstech.com/can-protocol-in-stm32/ (more detailed than I could explain - so this link)
2) The data from each node is distinguished by an identifier. It can be 11 or 29 bits based on the version of CAN you use.
