CMSIS(DSP) PID implemented in Mbed is not comlete?

[JohnK1987]

Description

Hi, I tried to use PID control from CMSIS implemented in Mbed-OS but compiler can not found functions like

• arm_pid_reset_f32 (arm_pid_instance_f32 *S)
• arm_pid_init_f32 (arm_pid_instance_f32 *S)

The old Mbed-DPS lib has same functions like here and it works

The Mbed-os has same description in the PID's doxygen documentation like Mbed-DSP but init and reset functions missing and can not be called. The PID will not work without the init function and must be added manually.

Old Mbed-DSP: The Pid init and reset functions exist in the mbed-DSP-arm_math.h file, start at line 1788 and in mbed-DSP-ControllerFunctions folder are .c files for the PID functions like reset and init.

Current MbedOS5: Arm_math.h is here but where I can found the "ControllerFunctions" folder?

All missing files are in "unsupported" folder.

So it is a misstake or did I misunderstand something? How I can correctly use the PID from the CMSIS?
