CAN is a bit of a... thing. I won't say we have a CAN controller in our chip (because of ...reasons), but I can say that the ESP32-S2 has a peripheral we call the 'TWAI (Two Wire Automotive Interface) controller'; which happens to be fully compatible with the peripheral you used to use for that on ...

Does anyone have any idea how to add/send custom headers when making an OTA firmware request? My custom firmware update server requires some custom information from the ESP32 before it pushes a firmware/SPIFFS bin...but I cant figure out how to adapt/slip in custom headers simultaneously with the OT...

Hi there, I have seen in internet that some people are compressing the bin file for OTA. Could you tell us that what library should i use to compress and decompress the bin file? and i have seen that it is done in esptool.py while flashing the bin file via serial port. Thanks Ganesh What was the so...

Couple options...

Change the partition table sizes

If you do not need OTA firmware update abilities, switch to a single partition

Remove the SPIFFS partition

Switch to the 16MB (128Mbit) version of the ESP32-WROOM32

Maybe a second CAN controller, support for MIPI DSI displays, and please keep the RMT peripheral, I just love it, it is very useful.

A second CAN controller would be amazing!!!!

Anyone else had luck updating SPIFFS via OTA? I cant seem to find much information on it... How hard is it to have the ESP32 download a compressed SPIFFS image via OTA, and then unpack it and write it into SPIFFS? Im using a 16MB flash unit, and downloading/writing a full uncompressed 11MB bin will ...

Is there any limit to how big you can make the SPIFFS partition? I upgraded my project to the new ESP32-WROOM32-D with 128Mbit (16 megabyte) flash chip due to wanting both more program space, and wanting a larger amount of SPIFFS storage. Im setting it up with 3MB app partitions (OTA), and the remai...

Whatever Espressif has planned for the future chip...please do NOT remove the CAN bus controller!!

@ dmaxben Just a few pointers regarding IDF CAN driver usage It's probably a good idea to use the member names when initializing a CAN message structure in case the order of the members change in the future versions of the driver. There are also a bunch of message flags documented here to set/check...

If you're running Windows-10....in my opinion dont bother with msys/mingw32, etc..

Just use WSL...its native!
