Understanding the new API changes
Posted: Mon Feb 03, 2014 5:33 pm
Hi all,
I've been trying to understand the new changes to the logging API so I've been going through the API documentation code and changing it over line by line where needed. I've got this piece of code that seems to compile okay but when the execution reaches the logging section it craps out with this.
Cheers,

Does anyone know if the crazyflie.log.add_config(accel_log_conf) was the right method to call? Has anyone had this error too and figured out what it was?
The code in question...
