Пуск CAN-трансивера на STM32

Многие STM32 микроконтроллеры обладают CAN трансивером. Даже не одним. В этом тексте я расскажу про особенности работы CAN-трансивера на STM32 (bxCAN). Вы узнаете как работает CAN буквально под капотом.

Currently working on a #canbus to #HomeAssistant gateway with #esphome that supports DBC files.
Problem: ESP32 needs a physical connection to said CAN bus.

Sane solution: physically move ESP32 contraption to the CAN bus.

ADHD brainfart:
Set up Raspberry Pi with MCP2515 and immutable Alpine Linux that runs off RAMFS. Cross-compile Cannelloni for aarch64. Tunnel CAN bus to local machine's USB-CAN adapter. While we are at it, include serial2net.

Yes, it works. Yes, I drank too much Club Mate.

N) 'amka' means, (M) wakes up (O) to receive (A) a #keycode to be broadcast on the #CANbus so that #ECU's (T, S, R) verify 'wah gwaan'🫣!

(B & F) also wake up (M), who in turn wakes up the (C, D, E, J, K, L, O) to send (G) tickle (A) to spit out angrily (H) #HapaUjanjaTu #keyprogramming #vag #vw #audi #skoda #seat #cartips #5021tips #diy #carkeyprogramming #AutoElectronics #magari

Just had a brainwave! If there was a #canbus integration, #homeassistant would know when the car needs refueling

Turns out it's not an original idea, which is fantastic! This WiFi enabled CAN adaptor looks like it's worth picking up...

Has anyone played around with get telemetry from their car into HA or any other fun integrations?

As then, NO #carimmobiliser #carkey data stored in the gateway module, R, a hub between different, #CANbus systems!
R, may require adaptation coding when replaced, be it offline (or online), #HapaUjanjaTu

M, just wakes up, O, via N, to receive data from, A, but could also need some adapting, seen🤔? #vag #vw #audi #skoda #keyprogramming #immoff #ecu #carprogramming #cartips #5021tips #autotips #autoelectronics #ecurepair #autoparts

Обзор реализации протокола ISO-TP с сайта Разработчики-Еноты

В этом тексте я произвел обзор Си-шной реализации протокола iso-15765 (он же ISO-TP), которую можно свободно скачать с сайта github в репозитории DevCoons. Определил достоинства и недостатки данной реализации ISO-TP протокола.

When you connect a scope to a vehicle’s CAN FD bus, you’re literally watching data fly at 8 Mbps.

Also entweder bin ich zu doof oder ich bekomme das SN65HVD230 Modul nicht zum laufen. Jedes mal, wenn ich versuche via CAN ne Nachricht auf den BUS zu schicken stürtzt mein ESP ab ... WTF? Mal sehen ob das mit den MCP2515 Modulen das gleiche ist. #canbus #can #ESP32 #platformio
