Posted on May 21, 2014 at 13:34Hello folks!
I'm developing a firmware using USB library of ST to STM32F407. My application is a Tester that test the communication of each device and the problem is: I can test the first and second devide, but I can't go on with test routine... and I don't know what else I can do... please, If someone has already worked with this library and can help me, I'll fell glad... below my code...
USBD_Init(&USB_OTG_dev,USB_OTG_FS_CORE_ID,&USR_desc,&USBD_HID_cb,&USR_cb);
Delay_ms(10000);
/* ''Conecta'' o cabo USB na BeagleBone (5v, D+, D- e GND) */
Set_5V_GND_USB;
Set_Test_BB;
/* Envia este vetor ''Buffer_Transceive'' pela USB */
Buffer_Transceive[0] = 0xFF;
Buffer_Transceive[1] = 'E';
Buffer_Transceive[2] = 'N';
Buffer_Transceive[3] = 'E';
Buffer_Transceive[4] = 'R';
Buffer_Transceive[5] = 'M';
Buffer_Transceive[6] = 'A';
Buffer_Transceive[7] = 'X';
do
{
USBD_HID_SendReport (&USB_OTG_dev, Buffer_Transceive, 8);
Delay_ms(500);
}
/* Aguarda os dados retornarem */
/* INCLUIR ''TIMEOUT'' */
while(Buffer_Receive[1] == 0);
USB_OTG_StopDevice(&USB_OTG_dev);
DCD_DevDisconnect(&USB_OTG_dev);
And the code repeat to another device... is there something wrong
#host #usb #stm32f407 #cdc
