The developer firmware only retains the functions of servo angle control, PID modification, servo calibration, servo angle feedback, fuselage attitude angle feedback, battery power feedback, shutdown protection, and low battery protection.
Compared with the default version firmware, the developer firmware can only be controlled through the serial port and cannot be remotely controlled through Bluetooth, but the overall control frequency is higher, the baud rate is changed to 1000000, and the bottom layer control frequency for the servo is 250Hz; canceled The read function is changed to send data frames to the upper computer at a frequency of 50Hz, including battery power, attitude angle, and servo angle data, and the data feedback is more timely. The feedback frequency of the servo angle is currently about 26Hz due to hardware reasons. The specific data frame format is shown in the following table.
It is recommended to use it with the developer version of the Python library and sample programs.
The default parameters of PID are 20, 0, 0. In order to protect the servo and circuit board, it is recommended that the PID parameter should not be greater than 60. developer firmware of XGO-Mini
