Hi,
I am using the sample example from MQX 3.4 version.
These are my observations:
1.When I send data using Hyperterminal, device sending back the same character.
2.I developed PC application which sends more than one character.This case always I am getting data size as( dp_rcv->data_size) 1.
When PC appliction sends data bytes, USB Device stack is generating USB_APP_DATA_RECEIVED event but with data size (dp_rcv->data_size) = 1
This code snippet is from function void USB_Notif_Callback(uint_8 event_type,void* val,pointer arg)(virtual_com.c)
else if((event_type == USB_APP_DATA_RECEIVED)&&
(start_transactions == TRUE))
{
uint_32 BytesToBeCopied;
APP_DATA_STRUCT* dp_rcv;
dp_rcv = (APP_DATA_STRUCT*)val;
BytesToBeCopied = dp_rcv->data_size;
for(index = 0; index<BytesToBeCopied ; index++)
{
g_curr_recv_buf[index]= dp_rcv->data_ptr[index];
}
g_recv_size = index;
}
