Thanks for your reply, I do have a bunch of Rasp Pi's and Uno's but ESP32 is new to me. Will order the parts you listed and build the setup and let you know once I have got in all in place and connected. Thanks for the help.
Hi Constantin, hope you are fine. If you would have time to provide the key for the ESP and fake config for the provided data it would be great, thanks MarcelFound a nifty device called “USB Tin” on Amazon, which comes with a win app “USB Tin Viewer” which allows me to view data coming out of the inverter, confirming its pin 2-CanH, pin 3-CanL and 4-GND, so that part is also resolved. Still see nothing in the info part of the app, when connected like that, but could also be because key is missing; chip ID is 9629e748 I do see the ESP sending data on the CAN so confirm that also works. Awaiting further instruction. Thks MarcelView attachment 182321View attachment 182322
Peter,I built the circuit with an MCP 2115, a SN 65HVD230 and a MAX 485. I want to use it to control an inverter, a JK BMS and two JK balancers. The ESP is running, but so far it is not connected to the JK. The BMS does not connect over Max 485, the balancers not over CAN. I measure DC voltage:
Balancer...H ground 2.5V+ L ground 2.5V+
ESP pin D4-Ground 3.56V+ D5-Ground 3.56V+
Does anyone have a suggestion

I am French and I use Google translate.
I would like to carry out the hardware part myself, do you think this diagram could work with your program?
How can I get your program?

Hi Paul, you need to load all 3 bin files to the ESP , please note the start adress stored in the file name. Bon Weekend !
I do not think it cares , just as long as you put the right files on the right address. It worked for me in the order as above 10000/8000/1000So this one first : 0x1000.bin, then 0x8000.bin and and for finish 0x10000.bin ?
