Hello,
I'm doing a project where Labview must communicate with a uC (microchip, mikroC PRO for PIC). Unfortunately, it doesn't work correct, sending data to the uC is good but cann't transmit data to the PC (Labview). The program remains in the loop "while (! HID_Write (& writebuff2, 64)). '
For writing and reading, I use the example program "USB RAW - bulk.vi". If I 'pushed the Bulkin button then I get the following error welding "Error -1073807302 occurred at VISA Read in USB RAW - Bulk.vi" but if I click Bulk Out, then I receive data in the uC.
Can someone help me maybe? thanks
Piece of uC code:
unsigned char readbuff2[64] absolute 0x500; // USB Buffers should be in USB RAM
unsigned char writebuff2[64] absolute 0x540; // USB Buffers should be in USB RAM
void USB_enable()
{
char cnt;
HID_Enable(&readbuff2,&writebuff2);
}
void USB_Communication()
{
char Read_Reg;
if (HID_Read())
{
switch (readbuff2[0])
{
case Reg_Addr_Software_Version: //read Software_Version
{
writebuff2[0]= Reg_Addr_Software_Version;
writebuff2[1]= Software_Revision_H;
writebuff2[2]= Software_Revision_L;
writebuff2[3]= 0;
break;
}
default:
{
writebuff2[0]= Reg_Addr_Automatic_Response_Warning;
writebuff2[1]= 0;
writebuff2[2]= Address_Fail;
writebuff2[3]= 0;
break;
}
}
while(!HID_Write(&writebuff2,64));
} // end HID_Read()
}
