ID Signal Note 1:400 SMOOTH_CRUISE_PING bit 20 some kind of flag/watchdog triggers at regular interval when moving above min speed X_COUNT_UP_10_SEC also contains 10 second incremental count in last byte.
You can use the save log button to get a csv file of the data, this only works with chrome and some versions of chromium.
The following converts the csv file to a sqlite3 database file name 'data.db', with a table named 'can' containing all the records.
import sqlite3 import pandas conn = sqlite3.connect('data.db') df = pandas.read_csv('data.csv') df.to_sql('can', conn, if_exists='append', index=False) # get and show 100 samples of wheel speed data with a time over 100 cur = conn.cursor() cur.execute("SELECT * FROM can WHERE addr = 464 AND time > 100 LIMIT 100") rows = cur.fetchall() rows conn.close()
