The pins' definition and setting method

① The pins' definition

Pin outputs are grouped with the same Timer, and the protocol of the pin output in the same Group is the same. When a pin in the Group is configured as DShot, the rest of the pins in the Group will also be configured as DShot and cannot be configured for other functions.
For example, when you plug the ESCs into the 1st, 2nd, 3rd, and 4th pins, all pins will be configured as DShot mode and cannot be configured as other functions. When other pins need to be configured in different modes, they need to allocate their pin functions reasonably according to the Group.

Solution: Insert the ESCs into Group 1 or Group 2, so that the other two groups of pins can be assigned to other functions.

② The pin distribution and setting method
The function of the pins can be selected in the [SETUP->Mandatory Hardware->Servo Output] menu.

The pin distribution of the CrossFlight is shown in the table below:
