Re: About the CAN controller.

I bought the WaveShare CAN Module.
I hooked it up and everything works fine.
I might have had bad chips.

Re: About the CAN controller.

I have a basic question:

1) How can I validate and test the CAN circuitry in the ESP32 DevKitC with only using a single DevKitC module?

I would like to validate that CAN works in the ESP32 DevKitC before buying a lot of other modules.

Re: About the CAN controller.

Hello, The CAN chip on the CAN board that I have, the VP230, does appear to be a SN65HVD23x 3.3V, when I do a google search. I did NOT try to connect two ESP32 together via the CAN bus. I only tried to connect the GPIO lines of a single ESP32 together for my tests. I read that shorting GPIO35 (RX) a...

Re: About the CAN controller.

On the DevKitC, I connected copper wires to the GPIO5 and GPIO4 ports and afterwards to GPIO5 and GPIO35 directly in separate tests. Do I need to use PULLUPS on the lines? Do I need to use physical PULLUPS or can I program the DevKitC to PULLUP the respective lines? (I assumed that the software demo...

Re: About the CAN controller.

CAN On ESP32 DevKitC I’ve been trying to get CAN working on my ESP32 DevKitC for the past few days now--all with NO success. I’ve successfully built and flashed 2 separate demos without errors. However nothing shows up on the output monitor when I do “make flash monitor”. I also did make flash and t...

Re: Full example of using spiffs with ESP32

Hello, Thanks very much. This is great. Everything works. I can flash and test successfully. However, one thing doesn't work. I cannot build the "mkspiffs" utility under Windows environment. Any suggestions would be appreciated. I get the following errors: Under windows, I get the following errors w...
