# RaceChronoDiyBleDevice
|
2020-08-21 10:20:07 -07:00
|
|
|
DIY BLE device for RaceChrono, currently supports reading data from the CAN bus.
|
|
|
|
|
|
|
|
|
|
There are some optimizations in the code that are specific to the FT86 platform
|
|
|
|
|
cars (Subaru BRZ, Toyota 86, Scion FR-S), but it should be straightforward to
|
|
|
|
|
tweak the code for other cars.

|
## Supported Hardware
|
|
|
|
|
|
|
|
|
|
* Adafruit Feather nRF52832
|
|
|
|
|
* Adafruit ItsyBitsy nRF52840 Express
|
|
|
|
|
* 16 MHz MCP2515 breakout boards (probably MCP25625 as well)

|
## Prerequisites
|
|
|
|
|
|
|
|
|
|
You will need to install two libraries for Arduino:
|
|
|
|
|
```sh
|
|
|
|
|
cd ~/Documents/Arduino/libraries/ # ~/Arduino/libraries on Mac OS
|
|
|
|
|
git clone https://github.com/timurrrr/arduino-CAN CAN
|
|
|
|
|
git clone https://github.com/timurrrr/arduino-RaceChrono arduino-RaceChrono
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
It's important that you don't use the arduino-CAN library available in the
|
|
|
|
|
Arduino IDE built-in library manager, as it has multiple bugs, and many
|
|
|
|
|
operations are implemented in an ineffective way. My pull requests to address
|
|
|
|
|
those have not been reviewed at the time of writing.

## Testing
|
|
|
|
|
|
|
|
|
|
You don't need to always be in the car to test changes to this library. Instead,
|
|
|
|
|
you can use the FakeSubaruBRZ example from my fork of the `arduino-CAN` library
|
|
|
|
|
on a second Arduino board, and connect the two boards into a small CAN network.
