Hi,

i created a USB-CustomHID project use CubeMx, but i can't find any way to change the size of Endpoint1(not Endpoint 0). Are there any ideas for my problem? Thanks.

Dear user,

This parameter is fixed within the HAL driver in the HAL_PCD_Init function - see code extract below:

/* Init endpoints structures */

 for (i = 0U; i < 15U; i++)  {    /* Init ep structure */    hpcd->IN_ep[i].is_in = 1U;    hpcd->IN_ep[i].num = i;    hpcd->IN_ep[i].tx_fifo_num = i;    /* Control until ep is activated */    hpcd->IN_ep[i].type = EP_TYPE_CTRL;    hpcd->IN_ep[i].maxpacket = 0U;    hpcd->IN_ep[i].xfer_buff = 0U;    hpcd->IN_ep[i].xfer_len = 0U;  }
