Chapter 3 Operating Principles | PCI-DMC-A01 / PCI-DMC-B01
3-2 Revised March, 2012
Click on the “Open card” button to execute the following procedure:
/* gDMCExistCards variable is set as the number of PCI-DMC-A01 on the PC*/
rt = _DMC_01_open(&gDMCExistCards);
2) Card initialization
Figure 3.3
Click on the “Card init” button to execute the following procedure:
for(i=0; i<gDMCExistCards; i++)
{
/* Get the card number of the i-th card on the PC. Card number is the value set by
the DIP Switch*/
rt = _DMC_01_get_CardNo_seq(i, &CardNo);
gpDMCCardNoList[i] = CardNo;
/*Check to see if the card has been initialized. If the value is 0, then the card has not
been initialized .*/
rt = _DMC_01_check_card_running(gpDMCCardNoList[i], &running);
if(running == 0) {
rt = _DMC_01_pci_initial(gpDMCCardNoList[i]); // Initialize card
if(rt != 0) AfxMessageBox(“Can't boot PCI_DMC_01 Master Card!”);
}
rt = _DMC_01_initial_bus(gpDMCCardNoList[i]); // Initialization communications
protocol
gbpDSPBoot[gpDMCCardNoList[i]] = true;
}
3) Establish communications
Figure 3.4
Click on the “Find slave” button to execute the following procedure:
rt = _DMC_01_start_ring(gDMCCardNo, 0); // Begin communications
rt = _DMC_01_get_device_table(gDMCCardNo, &gpDeviceInfo[gDMCCardNo]);
rt = _DMC_01_get_node_table(gDMCCardNo, &gpSlaveTable[0][gDMCCardNo]);
Once the above procedure has been executed, the detected Slave device is
displayed in the “Slave num” field.
