Re: How to compress and decompress the bin file for OTA

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...

Re: Sketch too big

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!!!! :D

Re: OTA update spiffs

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 ...

SPIFFS partition size limit??

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...

Re: Using the official CAN driver with Arduino

@ 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...

Re: ESP-IDF problems with mingw/mingw32/make

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

Just use WSL...its native!

Re: Can bus issue , stuck messages

Just use the ESP32's internal CAN controller! No need to use an MCP2515 with the ESP32 unless you specifically need more than one CAN bus. Once you've switched to using the ESP32's internal CAN controller, just use the correct ESP-IDF native CAN drivers. The Thomas Barth/Miwagner Arduino ESP32 CAN l...

Re: Using the official CAN driver with Arduino

Also, as a update, I was able to get the official ESP-IDF CAN driver working perfectly in Arduino with help from a friend who knows MUCH more about programming and the ESP32 than I do. Ive been having some problems with getting my WiFi Manager to work properly in the ESP-IDF, otherwise I would have ...
