v2.4.0

Cleanflight v2.4.0

Latest Cleanflight Configurator >= v2.4.0-RC1 is required.

Changes since v2.4.0-RC1:

• None, if you have flashed v2.4.0-RC1 you do not need to re-flash.

Changes since v2.3.2:

• Enhanced flight performance.
• Changes from Betaflight 3.4 merged.

Notes:

• Some features are disabled for some older targets like the NAZE32 and other targets with 256K flash or less. See https://github.com/cleanflight/cleanflight/blob/master/docs/Customized%20Version.md
• OSD users should use the latest font from the latest configurator.
• OSD Slave users should upgrade both the FC and their OSD Slave.

Known Issues:

• Manual needs updating, volunteers wanted!
• If you encounter issues with your settings not being correct after upgrading to the RC please report this via the feedback issue, then reset your settings and continue testing.
• The mixer setting in the configurator may not have any effect. See #2764 - configure a custom mixer and use the mmix cli command, see manual.
• Motors outputs need to be configured as servo outputs before using servos via the cli resource command.
• Use of motor outputs 5-8 on SPRacingF7DUAL requires 'NO_VTX' firmware, get it here: #3049 (comment)
• OSD Slave always says 'Waiting for FC', see #3062

Future:

• Cleanflight will end support for F1 based boards soon.

SAFETY:

• When upgrading follow this simple procedure: Disconnect battery, remove propellers, flash/upgrade, configure, connect battery, test rx, test motors, test arming - only then should you re-attach your propellers.

OSD Slave usage:

1. Flash CF > v2.x onto a compatible stacking FC (SPRACINGF3, SPRACINGF4EVO, SPRACINGF3EVO).
2. Enable OSD feature on the FC.
3. Enable MSP on UART1 on the FC.
4. Flash CF2.x onto the SPRACINGF3OSD/PDB board.
5. Upload Cleanflight font to the SPRACINGF3OSD using the 'OSD' tab, set video mode.
6. Connect FC + OSD using stacking pins and power on board boards.
7. Configure FC as usual.
8. Set the current sensor source to "MSP sensor/OSD Slave"
9. Access OSD menu using sticks by following on-screen prompts. (Yaw Left, Throttle Mid, Pitch Up)
