This just happened a week ago :o LittleFS is indeed a drop-in / transparent replacement for SPIFFS. Just replace all occurrence of SPIFFS by LittleFS in your code.

I suggest that to increase Patreon participation you may want to use a persistent ribbon, tag or other visual element that appears on the patrons info box to the left of each post. That can be arranged just like the bottom "pop-up" banner. We can rotate another one with Petreon, just have...

CAN Shields are not for beginners. MCP2515 can behave differently with different libraries (there are a few to choose from) I recommend plug-and-play USB dongle that your can read/write with software. https://www.tindie.com/products/lll7/can-usb-converter-uccb https://store.protofusion.org/product/c...

Did you set maximum SPIFFS size? arduino-esp-spiffs-max.png Why not try command line? Need these tools: Python 3.7+ mkspiffs.exe esptool.py Build mkspiffs.exe -c C:\FSB\FSBrowser\Data\ -b 8192 -p 256 -s 600000 flash-spiffs.bin Flash python esptool.py --port COM1 --baud 115200 write_flash 0x100000 fl...

All debug looks good, steps followed correctly. Maybe there is a bug with URL "/"?

Perhaps try full URL? -> http://192.168.4.1/index.html

I can suggest to "put on your programmer's hat on" and try to troubleshoot beyond ESP. Try to connect TX/RX directly into USB-TTL dongle (CH340/PL2303 ...of course with proper drivers installed). Open "putty" https://the.earth.li/~sgtatham/putty/latest/w64/putty-64bit-0.73-instal...

You can try removing not essential files from /Data folder.

Code: Select all

gauge.min.js.gz
gauges.html
gauges.js

dima

It sounds like your "Data" folder is empty, Johannes web interface folder structure does not reflect what is needed for Arduino IDE - ESP8266 SPIFFS Uploader.

make C:/FSB <-copy only FSBrowser.ino
make C:/FSB/Data <- Copy all files except FSBrowser.ino

I also tried Dimas wifi interface on D1 and it works smoothly. Weird? I have encountered the same issue, I had a work-around ..."auto refresh the page if detect 2D text" in web-interface. What happens is boot loader 2D text is getting through to esp8266 serial on start-up. What is even st...

I flashed another esp8266 with Dima's interface and no luck on either Blue Pill nor fully tested GS450h-VCU. On both I get the error: ' SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data:'. GS450h-VCU will not work with Johannes or my web-interface. You will need to...

Johannes can you allow ".drawio" or ".xml" file upload in Wiki?
I was going to upload the original diagram for public editing.

Original diagram can be edited with https://draw.io

Wow this is a discovery for me. It existed all this time

No need to do anything, send CAN and get a reply. Just works.

Excellent!

EDIT: Well not 100%, obviously getting "udc" will not work ...because it is out of parameter index.

dima

I wonder if we should poll the more obscure values via CAN SDO instead of mapping everything somewhere? https://openinverter.org/wiki/CAN_communication#Setting_and_reading_parameters_via_SDO The way it works: send a request message for the value you want and receive the reply. If we agree on this I...

This page needs help > https://openinverter.org/wiki/CAN_table_CAN_STD This will help with "universal" dashboard or any other interface relying on CANBus messages. Make up a standard :) Maybe grouping things logically by functions ...I don't know if "AUX 12volt" belongs together ...

Wanted to visually document ESP8266 to MCP2515 development.

TJA1050 requires 5V but the inverter ESP8266 powered by 3.3V. We can still power MCP2515 chip with 3.3V but need to isolate CANBus chip by cutting off back PCB VCC trace. Then give TJA1050 separate 5V.

With these settings you posted above and an FTDI board connected as you originally posted, have you or Arber successfully managed to flash one of these boards with the latest Arduino IDE and esptool.py v2.6? Yes all the time. Only difference not using expensive FTDI (You will need USB to TTL not RS...

Thanks Elon. Ready for live test! ESP8266 binary here Once loaded you will need to switch the view (default is Open Inverter). Click the background, the view will flip, then select "View Menu" -> Lexus GH450 gs450-vcu_test1.png Turns out connecting ESP8266 to CAN is not easy, full SPI conn...

let’s NOT spend development time/effort on building what’s already been built. Woof ...where is the excitement? Oh wait this is the Internet. Just looked into RealDash ....no source code! The main reason anyone is doing this is to "Learn". And you cannot learn without do (speaking like yo...

Out of pure excitement!!! I am going to build the First Beta .

Does this make the version Damien started defunct? If so I'll cease making changes. No discouragement. This new CANbus-ESP8266 project is ambitious :o May look great but so far out from being functional (hope more people join the development) Being developed on the side of a desk ...not real-world ...

dima

Thanks for feedback, much appropriated. At the moment ironing out the GUI and then will focus on adding functionality. It would be helpful to post relevant CAN messages that you want gauges to be build for. First fault I get is: Class MCP_CAN has no member 'sleep' Do I need all the libs. that you us...
