"Hello,
I have a 6602 counter/timer board.
I'm trying to use DIO with DDK on Windows system.
When I configure pins 0 to 7 in output, pins 0 (PFI_0) and 4 (PFI_4) goes to logic level "1".
If I write with DIO_Parallel_Data_Out a sequence of number, pins 0 and 4 never changes its state.
This is the code, based on gpct_ex*.cpp:
//DIO example code starts here
void test(iBus *bus)
{
tAddressSpace cardSpace;
tTIO *board;
int i;
cardSpace = bus->createAddressSpace(kPCI_BAR1);
board = new tTIO(cardSpace);
//Configure all 8 Digital lines as Output
board->IO_Pin_0_1_Configuration_Register.writeIO_Pin_0_Se lect(1);
board->IO_Pin_0_1_Configuration_Register.writeIO_Pin_1_Se lect(1);
board->IO_Pin_2_3_Configuration_Register.writeIO_Pin_2_Select(1);
board->IO_Pin_2_3_Configuration_Register.writeIO_Pin_3_Select(1);
board->IO_Pin_4_5_Configuration_Register.writeIO_Pin_4_Select(1);
board->IO_Pin_4_5_Configuration_Register.writeIO_Pin_5_Select(1);
board->IO_Pin_6_7_Configuration_Register.writeIO_Pin_6_Select(1);
board->IO_Pin_6_7_Configuration_Register.writeIO_Pin_7_Select(1);
//Write data to DIO, only one bit high at time.
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(1);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(2);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(4);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(8);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(16);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(32);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(64);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(128);
board->DIO_Output_Register.writeDIO_Parallel_Data_Out(0x0);
//Configure all 8 Digital lines as Input
board->IO_Pin_0_1_Configuration_Register.writeIO_Pin_0_Se lect(0); //0='input'
board->IO_Pin_0_1_Configuration_Register.writeIO_Pin_1_Se lect(0);
board->IO_Pin_2_3_Configuration_Register.writeIO_Pin_2_Select(0);
board->IO_Pin_2_3_Configuration_Register.writeIO_Pin_3_Select(0);
board->IO_Pin_4_5_Configuration_Register.writeIO_Pin_4_Select(0);
board->IO_Pin_4_5_Configuration_Register.writeIO_Pin_5_Select(0);
board->IO_Pin_6_7_Configuration_Register.writeIO_Pin_6_Select(0);
board->IO_Pin_6_7_Configuration_Register.writeIO_Pin_7_Select(0);
delete board;
bus->destroyAddressSpace(cardSpace);
}
Does anyone know what is the problem with it?
Thank you"
