Does it make sense to write a CCS module for dalas battery emulator? There's already Chademo

You need to connect to the relevant can on the working car, record some action, IE driving, save the log. Clear repeat for charging etc. Record the same bus on your setup, save log. Compare files, filter out id's that are present on the log from your car and reply the remaining IDs to your setup. Ho...

I've updated the title of the first post, I'm not going through 8 pages to update them all unless I get really bored

Not for sale. Whole thing is free, want rid of it but seems a shame to scrap.

Removed because it was making a noise, see: https://www.youtube.com/watch?v=cNceRoMUGiY&feature=youtu.be I couldn't figure out the cause and didn't make a noise outside of the car https://photos.app.goo.gl/Vs7i2pz3hzdW2SLp6 It might be OK to use, or just for playing around with. Need to clear so...

So, just had a couple of box fresh Lilygos delivered to do this. Here's the esptool command, all binaries in the attached zip. esptool.py --chip esp32 --port "/dev/cu.wchusbserial58CE0145831" --baud 460800 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_fr...

Ok so the bootloader is too large. Need to shrink it.

Screenshot 2024-10-21 at 1.30.11 pm.png Still digging at this, So if I've got just the bootloader on using openocd/gdb to step though, everything executes as expected. If theres any firmware, then in the bootloader hwinit.cpp in can_setup() on the line nvic_enable_irq(NVIC_USB_LP_CAN_RX0_IRQ); it s...

If using Zombieverter, it supports using FOCCCI (or will in the next release) as the charging interface, so foccci deals with the CP and PP signal, and then zombie replicates the CP duty on a pin for the OBC to use. I've been using this setup for a month or so, it works great.

It's getting the values from zombie. So depends on components used, but BMS/Shunt integration populates the spot values and the UI grabs them for display

are you using Windows? I've some fresh boards coming and will do some step by step instructions for boards out of the box. I don't use windows usually but got an old windows laptop that I'll use for it. The bad size given might be a library version issue https://github.com/espressif/arduino-esp32/is...

Using it to supply the contactors 12v using a relay on the negative contactor output on zombie is how I'd do it, unless you want to have a specific error in zombie for it. For me Precharge failed would be a sufficient error.

No, I don't get the single 2 and no response to the reset or json command. Very strange.

So using the python script when there's firmware on there: python updater.py --device /dev/tty.wchusbserial1420 --file ~/code/stm32-CANBridge/stm32_canbridge.bin File length is 19992 bytes/20 pages Resetting device... Sending number of pages... Sending page 0... Sending page 0... Sending page 0... S...

There's no firmware on, it boots in to firmware and gives params if I flash the bin with stlink. https://github.com/jamiejones85/stm32-CANBridge It's pretty strange, I can use the UART to flash if there's no firmware on there, but once theres firmware it wont flash with UART, just hangs at Upload Co...

Just using the esp32 webui can backend, that works with other nodes so should be ok.
https://github.com/jamiejones85/stm32-C ... /BlueBoard is what I've changed so far. The CRC clock is enabled

Got a strange issue in that the update get stuck at 5%. Any pointers as to where to look?

Got it working on the UART web interface now, thanks, that did it.

Must have messed something up then, though the bootloader is working, and can flash my app, but once it boots the uart isn't working. I've updated the Terminal to use UART 4 and { UART4, DMA2, DMA_CHANNEL5, DMA_CHANNEL3, GPIOC, GPIO_UART4_TX, GPIOC, GPIO_UART4_RX }, Probably off topic for this threa...

I'm not all that familiar with the lower level stuff, but I guess it's needs more than this to configure.

I want to use the template to make a can gateway so that I can update it over can. I've got the bootloader running on it now. Moved to UART 4. Next up hello world with template

I'll be starting with https://github.com/jsphuebner/stm32-template, will modify the code for 25MHz unless there's a compelling reason to switch the crystal.

Will this bootloader work on a STM32F105?
Want to attempt to run one of the cheap aliexpress can bridges with the openinv ecosystem https://dangerouspayload.com/2020/03/10 ... er-device/

You're unlikely to find much useful data via the OBD2 port the can on there is usually gateway'd you'll need to access the can bus the engine is on directly. As for your Christmas tree, check you've got the high and low pins correct, that would be most likely. Other is of your can bus shield has a t...
