Hi
I am beginer in using can festival,
finally i decided to switch to linux,
I can change value in PDO mapping and access that in both master and slave,
But when I use SDO with this method:(this method is in win32test example)
UNS8 ReadSDO(UNS8 nodeId, UNS16 index, UNS8 subIndex, UNS8 dataType,
void* data, UNS32* size)
{
UNS32 abortCode = 0;
UNS8 res = SDO_UPLOAD_IN_PROGRESS;
// Read SDO
UNS8 err = readNetworkDict (&TestSlave_Data, nodeId, index,
subIndex, dataType, 0);
if (err)
return 0xFF;
for(;;)
{
res = getReadResultNetworkDict (&TestSlave_Data, nodeId, data,
size, &abortCode);
if (res != SDO_UPLOAD_IN_PROGRESS)
break;
sleep_proc(1);
continue;
}
closeSDOtransfer(&TestMaster_Data, nodeId, SDO_CLIENT);
if (res == SDO_FINISHED)
return 0;
return 0xFF;
}
and this call:
unit32 data;
ReadSDO(nodeId, 1000, 0x00, unit32, data, sizeof(data))
I cant get any value as data
I checked edit .od file and the address I used, the value exists for
them. it is same as .od file of TestMasterSlave
I used canOpenShell but on calling funtion ssta,etc I got Segmentation
fault and core dump error
many thanks for your help
