from tools.lib.route import Route
|
|
|
|

|
route = Route('3533c53bb29502d1|2019-12-10--01-13-27')
|
|
|
|
|
|
log_paths = route.log_paths()
|
|
|
|
|
|
events_seg0 = list(LogReader(log_paths[0]))
|
|
|
|
|
|
print(len(events_seg0), 'events logged in first segment')

Stream replayed CAN messages to EON
|
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
|
|
**Hardware needed**: 2 x [panda](panda.comma.ai), [debug board](https://comma.ai/shop/products/panda-debug-board/), [EON](https://comma.ai/shop/products/eon-gold-dashcam-devkit/).
|
|
|
|
|
|
|
|
|
|
|
|
It is possible to replay CAN messages as they were recorded and forward them to a EON.
|
|
|
|
|
|
Connect 2 pandas to the debug board. A panda connects to the PC, the other panda connects to the EON.
|
|
|
|
|
|
|
|
|
|
|
|
Usage:
|
|
|
|
|
|
```
|
|
|
|
|
|
# With MOCK=1 boardd will read logged can messages from a replay and send them to the panda.
|
|
|
|
|
|
MOCK=1 selfdrive/boardd/tests/boardd_old.py
|
|
|
|
|
|
|
|
|
|
|
|
# In another terminal:
|
|
|
|
|
|
python replay/unlogger.py <route-name> <path-to-data-directory>
|
|
|
|
|
|
|
|
|
|
|
|
```
