Micro introduction: A CANbus, which is used to connect all computers in the car, can only carry chunks of 8 bytes plus an ID, called frames. All data used to actually operate the car, such as switch positions, speed, and…

CanSee dongle v2
Too impatient to wait for the ODB2 cases to arrive, I reused my ELM732 WiFi dongle I didn’t use anyway, to build a second CanSee dongle. LED’s have been put into a new order and the interior is somewhat cleaner.…

New material arrived … So let’s wait for the ODB2 cases to arrive before the fun can start 😉
DIY dongle build and documentation
While heavily a Work in Progress, Bob has started to put together some decent documentation on the dongle. It’s in the development branch of the firmware on gitlab, look here for odt and pdf versions. Have a peek and maybe…
CanSee dongle in DIY mode
My current development dongle already looks somewhat clearer, now that it got it’s case, but under the hood, there is still room for improvement. The second transceiver has recently be added, still it is not being used right now. So…
Dongle build: from breadboard to veroboard
Here is an example on how I build my dongle prototype. Note that this is not fitted in a real dongle case. It’s slightly too big for it and at the moment this my only ESP32 board and I want…
Dongle firmware
The software consists of a few functional parts. First, there is the CANbus library. While the ESP32 is around for a while now and there is good CAN support in Espressif’s IDF, the support in the Arduino environment is mediocre…
Dongle testing (more geek talk)
You might want to have a peek at this “Frankenstein contraption” testing rig. Things have moved on since (more on that in a later post), but this is how projects like this start. Note that I laid it out neatly…
A DIY CanZE dongle
The KonnWEI dongles are, though the most stable in terms of what you get when you buy, not the best to run CanZE with, especially when fast performance is required. Think like the Driving, Braking and Consumption screens. For the…
Dongle tester app
Why does my dongle not work? Is it working? What version is it? Why do only some of the values get displayed? I recently discovered an app that can test a dongle and tell you what version it is, so…
