Posted on February 14, 2017 at 11:562. I'm trying to send signals DSR and DCD through the structure and command endpoint, see example
USBD_StatusTypeDef USBD_LL_SOF(USBD_HandleTypeDef *pdev)
{
static uint8_t Buf[0xA];
Buf[0] = 0xA1;
Buf[1] = 0x20;
Buf[2] = 0;
Buf[3] = 0;
Buf[4] = 0;
Buf[5] = 0;
Buf[6] = 2;
Buf[7] = 0;
Buf[8] = 0x2; //0x3; ///Var_O->Gsm_Modem_Line_Signal; // //0x2;
Buf[9] = 0x0;
if(pdev->dev_state == USBD_STATE_CONFIGURED)
{
USBD_LL_Transmit(pdev, CDC_CMD_EP, Buf, 10); // Send DSR and(or) DCD
if(pdev->pClass->SOF != NULL)
{
pdev->pClass->SOF(pdev);
}
}
return USBD_OK;
}
but the signals are not visible in the terminal, although the SPL works.....
What I'm doing wrong?
