These are min/max values (in us) which, when a channel is smaller (min) or larger (max) than the value will activate various RC commands, such as arming, or stick configuration. Once midrc is set, use subtrim on transmitter to make sure all channels (except throttle of course) are centered at midrc value. Note the value most channels idle at - this should be the number to choose. A way to find out if this needs to be changed, is to clear all trim/subtrim on transmitter, and connect to GUI. Most standard receivers will have this at 1500, however Futaba transmitters will need this set to 1520. This is an important number to set in order to avoid trimming receiver/transmitter. Setting too high refresh rate can mean that FC cannot keep up with the gyro and higher gyro_sync_denom is needed. Note that different targets have different limits.
Use gyro_lpf and gyro_sync_denom determine the gyro refresh rate. Loop will always wait for the newest gyro measurement. In this case the loop will be synced to gyro refresh rate. Setting this to ON increases the processor speed, to move the 6th harmonic away from 432MHz.Įnabling this feature speeds up IMU speed significantly and faster looptimes are possible. Setting it to zero does not limit loop time, so it will go as fast as possible.ĭefault value is OFF for 72MHz processor speed. Default of 3500us/285Hz should work for everyone. Changing this affects PID effect with some PID controllers (see PID section for details). Serial passthrough mode, reset board to exitĬlick on a variable to jump to the relevant documentation page.

You may find you have to copy/paste a few lines at a time.Ĭompare the two backups to make sure you are happy with your restored settings. Use the CLI and send all the output from the saved backup commands.ĭo not send the file too fast, if you do the FC might not be able to keep up when using USART adapters (including built in ones) since there is no hardware serial flow control. If you blindly restore your backup you would not benefit from these new defaults. For instance, in December 2014 the default GPS navigation PIDs changed. When restoring from a backup it is a good idea to do a dump of the latest defaults so you know what has changed - if you do this each time a firmware release is created youwill be able to see the cli changes between firmware versions. Copy screen output to a file and save it.
