All the above would either need modifiying the SAM3X code to get the correct format on serialdebug to drive the Nextion display or an external processor to covert from async serial to Nextion/I2C. I think the suggestion from a few days ago of using CAN bus and arduino would be best. This would also ...

Zombieverter declares Voltage in the header file so you will need to declare in your code, int32_t Voltage.

Available from TE website, https://www.te.com/usa-en/product-DTM13 ... BR008.html
down the page a little under CAD files.

V8 schematic and BOM here https://github.com/jsphuebner/Tesla-Fro ... /master/V8

Zombieverter code uses int32_t for Voltage and sign extends from 24 bit value to 32 bit.

Voltage=((bytes[2] << 16) | (bytes[1] << 8) | (bytes[0]));
Voltage = (Voltage<<8) >> 8; // sign extend

you could then convert to float with the multiplication by 0.001

https://github.com/jsphuebner/esp8266-web-interface is best place for ESP8266 code, Damien's appears to be specific to the GS450_VCU and only displays some battery parameters. One thing to note if updating the ESP code is that zombieverter ( and sine_vcu ) use 2 stop bits on the 115200 speed serial ...

Try reloading the bootloader via stlink. If the bootloader is corrupted the main application will not run.

They open in Kicad 7.0.

SN65HVD234 CAN transceiver needs EN pin pulling high. If not using enable pin better to use SN65HVD230.

GS450S does not use can bus it uses two serial buses. Torque is on htm so that looks ok, inverter voltage, INVudc is on mth so check mth connections.
Temperatures, tmphs and tmpm, are also on mth so checking these values will confirm if it's a bad mth connection.

Electrically they are the same part it is just qualification and maybe some testing that is different.

The info is in the data sheet but the -F085 is qualified to AEC-Q100 which is an automotive standard so should be suitable if you can find them. The only parts available from LSCS Electronics is the FAN3122TM1X-F085 which has the exposed pad on the bottom. This might work with some added insulation,...

Have you added linbus.o to the OBJSL list in the makefile?

There is no need to reset the board to upload but I find occasionly the wifi module needs resetting after. This is easy if working on the bench with the Wemos module as it has a reset button, otherwise power cycle the board. Are you using a board from Damien with the firmware pre-intstalled?

Either you have DualChannel selected with a single pot attached or pot2min and pot2max need setting or a wire is broken/not connected.
Check the pot and pot2 ( if using DualChannel ) spot values to see that the values are changing with the throttle pedal.

Voltages match SimpBMS I far as I can tell. It's matched to 10/11mV so not easy to see any errors as the voltages are so close. I worked out the DBC from SimpBMS but as it uses masking of ID to determine each cell it was not it was not obvious which ID related to each cell. That explains the extra w...

I bought a 12KWh Dec 2020 pack last week. Got S-Box switching and voltage and current readings working a couple of days ago and working on BMS today. Took an hour or so to work out the problem with the connection ( have since found a post from March 2021 but not on wiki ), as it appears to have chan...

I did this just to avoid cutting the cable for now. I can still connect the BMS master and log CAN messages etc.

It needs four links on the black connector 10 - 13 CANH, 23 - 26 CANL, 16-18 0V and 1 - 5 12V. On the external wiring loom red and grey/purple are 12V and brown is 0V.

It looks like the data is little endian so it's just going from 0x500 to 0x4FF, 1280 to 1279 dec, not sure where 1087 ( 0x43F ) came from. If you want 1200 to be the minmum you need if (x < 1200) x = 1200; as map will just produce a negative number. Without the /4 in your calculation 1200 is about 3...

The PCB layout tool is DesignSpark. Its placement file is not very compatible with JLCPCB. I have manunally adjusted the location and rotation in attached file. Check carefully as there could still be some mistakes. While doing that I noticed that the clearance between USART_RX and GND pin on STM32 ...

A quick image search suggests it is propably a Siemens 1DB2024 – WS36. 6 ph requiring dual inverter

Are you using DBC file to interpret messages?
EV-can_ZE0.dbc has B6 of 0x1DA as a message counter that cycles between 0 and 3.

Should '42 - interface' not be an option as apposed to the bullet points currently shown? - please see my attachment for reference! It's because the valid number of interfaces has changed from 0-3 to 0-2. If you had Leaf_PDM selected it is now invalid ( it is now selected by chargemodes ). To fix t...
