Custom HID Device (Joystick)

[MHovi.1]

Hi there,

I have an old joystick which i want to convert to a custom hid device, the stick has three shiftin registers (cd4201) which i am reading using spi1. I know these shift register are being read cause i am sending it to serialport3 (just for debugging)and read values in docklight.

I have set up mu nucleo F413ZH as a custom hid device and my computer is detecting it as hid game device. I have generated my own report descriptor and is 65 byte long.

Following some tutorials spread over the net i cant get it to work.

By not work i think my data is not being send by using the USBD_CUSTOM_HID_SendReport.

I have set my EPIN and EPOUT to 64 bytes as recommended in various topics. But nothing is happening . But when i set my EPIN to 2 bytes and EPOUT 64 byte buttons in my device manger flashing randomly. And Axis values are all over the place.

My code is not fully done jet, for now I just want to see if my buttons are working in my device manager.​

I have added some code

Report descriptor

__ALIGN_BEGIN static uint8_t CUSTOM_HID_ReportDesc_FS[USBD_CUSTOM_HID_REPORT_DESC_SIZE] __ALIGN_END =
