This is awesome. But is there an updated can controller for CAN-FD as this is now the most common protocol?

Hey! I just received my shield, I connected to the ESP32 and flashed through the website. Red and green light are on when I connect to the car, but it the blue light remains off, but it reads the canbus messages on Saavycan. But my question is, I know Volvo's canbus pins are 3 LS CAN - high, 11 LS CAN - low and 6 is CAN High ISO 15765-4 and 14 is CAN Low ISO 15765-4. I need to listen to LS CAN because I am trying to find some other warning lights on my Volvo so I can use on my simulator, when I ran the scan it read several Can ids and messages but none that I know that are available on my LS Can like for instance I know the my gauge uses 0xA10408 for the blinker, but that never came up on Saavycan, maybe I am listening to the high speed can? Is there a way to set to listen to can low on pins 3 and 11?

Excellent explanation and video, many THANKS. Hope you make video about STM32 projects with Arduino IDE.

what about the timestamp issue ?

Short and seet, Thank you!

is it possible to change tasmota to esphome ? i would like to create this DIY doorbell, but I already have ESPhome with an ESP32 and a doorbell camera using it

OMG i love this really work I hope it work on esp32

You can do the same with any esp32 using Bluetooth

i liked her voice

But wifi is super unstable if you live in an urban area. I tried bluetooth BLE but i cant find a freaking good library that can provide easily a simple host BLE (Python, Node, C#). Everything in C# seems targeted for Xamarin lately, the same with Kotlin and Android. With this I mean send the data from the ESP32 to my NAS server with bluetooth

Hi, really nice design, does this board have any certification like FCC, CE, RoHS, ISED, IATF16949...?

Lose the brim

I'm inspired. I've been trying to get audio output from a D1 Mini for a while. The PWM output on a GPIO seems to be software only, and there's a lot of interrupts going on, so it was quite poor. this looks like a "serial port abuser". I'll look closer. My use case is almost exactly the same as yours: I want to subscribe to an MQTT topics and have it say the words!

+1 for PCBWay

What's bgcode

is the ESP32 CAN Bus Shield soldered when delivered?

Can you publish the code you have on your online flashing site of this project? Since i have a car that uses 47,619 kbit/s can speed and have to make some modifications.

Excellent Job, very interesting

I have tried ESP32RET but with esp32 boards from aliexpress the can bus speed was not correct. First guess was that there is something wrong with prescalers in the source code but haven't found the culprit.. 100kHz speed in reality was about 99.8kHz and it was anought for data missmatch

Do we still need to email from our order for the source code or is it available somewhere online?

need to somehow integrate a bypass for Stellantis/FCA CANBUS security gateway here... I have no idea what that would involve though

This is really cool! I've not been successfully been able to compile something that actually was able to read the CANBUS. So having a prebuild image I can just upload is of great help. However, how were you able to connect to the wifi with such a short password? I'm unable to connect my mac to the ESP32.

haha really? :) I made similar project (but with LTE + GPS) few weeks ago :) ua-cam.com/video/IS6uzyXSnOA/v-deo.html Good job!

Good work. I am wondering if you didn't encounter any problem with Collin80's code? I remember when I was working with his code I couldn't make it work on my ESP32 board. It was some years ago and then I let it go.

What about using a elm327 instead of needing a can adapter?

Has anyone else has issues with getting a response from a button press? Heaps of data is auto-magically going from the "Can Gateway" to SavvyCan, but when I try to map a button by pressing it I'm not getting any new entries in SavvyCan. Car: BYD Atto 3. All equipment purchase through MrDIYCA (minus 1 of the ESP boards)

I may have missed it, but is there a link to that printed case?

i did a force quit on the adobe illustrator one and i still cant see a preview of my EPS file when I click space bar.

I see a few QuickLookUIService options but none of them say PID like your video. they either say "finder" or "firefox" or "preview" or "adobe illustrator". should i force quit all of them?

Thank you.

Anybody here? Walmart has them in clearance for 10 bucks

THANK YOU

I find ESPHOME easier. Also if you plan to use HomeAssistant, ESPHOME is built in. I have tried and succeeded with the Arduino IDE, but since I don't like C++ I prefer not to use it.

Voice-over Erratum: You mentioned the human hearing frequency range as 2 Hz to 20 KHz, but the onscreen description displays the accurate values.

If I'm using a USB to serial cable (one side have micro usb connector and other side have 4pin RX,TX,GND,VCC)instead of soldering it directly to the board then RX and TX work with ESP 8266 board? Please reply soon 🙏

I must be the outlier in this. I use ESP32 + DHT11 on battery powered (LP103395) sensors taking readings every 10 minutes pushing it via wifi to an MQTT server and I'm getting around 8 months per charge on the battery. I also have an SH31 variant that I'm testing, The variance between the sht31 and DHT11 is 0.5 degrees, which IMO is negligible in a domestic environment. I don't use an AT Tiny or anything to wake the esp32 I just deep sleep it - I might look more into it. I'm getting ~24uA drain when sleeping, I have a resistor divider for battery measurement (no switching) so without that I suspect it'd get to 12uA. I don't power down the dht11 at all it's power drain is tiny and the least of my current usage issues. I've seen a couple of your ESP-NOW videos and might try it out to see how it goes, my wake time is about 3.5 seconds, so I'd like to cut that as much as possible. I'm still using dhcp addressing rather than fixed IP addressing so that might account for some of it but it makes it very flexible so there's a trade off. I guess I'll also be building my own gateway, given the esp32 prices I'm happy to use 2 of them and was quite interested in your design too but I think rather than an SD card I'd use a remote config pulled at boot - or even config stored on the MQTT server.

Got the new generation board a couple weeks ago and assembled it all. Programmed the gateway code from your online programmer and it boots up fine. But no messages being shown in the log interface. I can see CAN transactions with a scope on the bus wires. It’s not a Tesla. Ideas for debugging steps ??

I want to build a project that connects 50 speakers (every speak has its different esp that connects) to a webpage and play music on all the speakers together. Please guide me on how I should start.

is there a version for a esp32 nodemcu?

Do you have any ideas for how to get an offline tesla back online?

Great content

Very elegant code, more clever than the other related codes! Congrats!

Really? Just run MouseJiggle (portable, no installation) and no annoying in-video ads.

At 3 minutes: at what point can you release the button?

py script: import mouse mouse.move

I think your heart is in the right place, but how about posting the source code and we can upload it to the device ourselves. Plugging an esp32 device in and flashing it with some unknown code from your website and then plugging it into my work PC (or any PC for that matter)… not gonna happen. It’s 2024. People need to be smarter than that.

ok nice project: get a problem with the firmware that you direct flash from the browser. work perfect on one notifier. but if i try to add a second notifier on my network with a different mqtt topic, the 2 notifiers get a spam of mqtt message and run in loop. if i switch off one of the notifier, all is now ok on the remaining notifier. i tryed to flash on one of the notifier the firmware from the current source code (Firmware config version 'MrD3') .the problem of loop is not there, but i can't play anything on this notifier (no output, no error... no status playing nor idle in the mqtt message) edit: seem that the mqtt topic configuration of the direct flash firmware accept a name like XXXXXXX, and the source code one need a /XXXXXX (with a /)
