Beware of fake ELM327 OBD-II Bluetooth adapters

Cheap ELM327 compatible OBD-II Bluetooth adapters that connect to your car for diagnostics and retrieve engine and other data are available all over the Internet. But today, we were reminded that many are fake with a partial implementation or not working at all. ELM32 was originally created by Elm Electronics – which recently decided to close shop – and based on Microchip PIC18F2480 microcontroller to provide the data through a UART interface, but copies have been around for years, and I myself bought a cheap ELM327 compatible ODB-II Bluetooth adapter back in 2013, but I never managed to make it work. Those were brought back to my attention today, as Jasbir bought two such fake ELM327 adapters on Aliexpress for under $3 each. The device reports itself as ELM V2.1 with firmware version “TDA99 V0.34.0628C”, it’s extremely buggy and certainly not feature-complete for an ELM V2.1 device. When he opened […]

CANDuino v3 – A Microchip ATmega168PA board with CAN bus, Arduino Nano form factor

CANduino v3 is the third revision of MassiveButDynamic’s CAN bus board with Arduino Nano form factor based on Microchip ATmega168PA 8-bit AVR microcontroller, Microchip MCP2515 CAN controller with an SPI interface, and Microchip MCP2551 CAN transceiver suitable for 12V and 24V systems. The CANDuino v3 board is now slightly narrower in order to give access to two rows on each side when installed on a breadboard, comes with a USB Type-C port to reduce the number of cables needed, and the CAN bus function can be deactivated via a jumper in order to use the CANduino as a normal Arduino Nano. CANDuino v3 specifications: MCU – Microchip ATmega168PA 8-bit AVR microcontroller @ up to 16 MHz with 16KB flash, 512 bytes EEPROM, 1 KB SRAM CAN Bus CAN L/H header and CAN bus termination Microchip MCP2515 CAN controller connected to the AVR microcontroller over SPI. Supports CAN V2.0B at 1 […]

can2040 project adds software CAN bus to Raspberry Pi RP2040 microcontroller

Raspberry Pi RP2040 can2040 software CAN Bus

The can2040 project is a software CAN bus implementation for the Raspberry Pi RP2040 microcontroller that leverages programmable I/Os (PIO) to achieve reading and writing CAN 2.0B data frames at rates up to 1Mbit per second. Kevin O’Connor, the developer of the project, further explains the implementation uses only one of the two RP2040 PIO hardware blocks, so it is possible for a single Raspberry Pi RP2040 chip to have two separate CAN bus interfaces. Some processing also happens on one of the Arm Cortex-M0+ cores of the microcontroller with the processing time dependent on the amount of bus traffic, and a fully saturated CAN bus at the fastest supported rate of 1Mbit/s may use up to around 30% of that core when clocked at 125MHz, so that should still leave plenty of room for other tasks that may run on the system. I could not find any information about […]
