How to use this Demo Application
1. The program must control I/O device, when you use this you must change user to root, you can use this command "sudo su"
2.enter "./CIO_Utility_console -h"show help function
Example:
CIO_Utility_console --4i4o 1
F75111 Layout Picture
Introduction
Initial Internal F75111 port address (0x9c)
define GPIO1X, GPIO2X, GPIO3X to input or output and Enable WDT function pin
Set F75111 DI/DO ( sample code as below Get Input value/Set output value )
DO: InterDigitalOutput(BYTE byteValue)) DI: InterDigitalInput()
PULSE mode
Sample to setting GP33, 32, 31, 30 output 1mS low pulse signal.
{
this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_PULSE_CONTROL, 0x00); //This is setting low pulse output
this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_PULSE_WIDTH_CONTROL, 0x01); //This selects the pulse width to 1mS
this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_CONTROL_MODE, 0x0F); //This is setting the GP33, 32, 31, 30 to output function.
this->Write_Byte(F75111_INTERNAL_ADDR, GPIO3X_Output_Data , 0x0F); //This is setting the GP33, 32, 31, 30 output data.
}
Initial internal F75111
void F75111::InitInternalF75111()
{
this->Write_Byte(F75111_INTERNAL_ADDR,GPIO1X_CONTROL_MODE ,0x00); //set GPIO1X to Input function

this->Write_Byte(F75111_INTERNAL_ADDR,GPIO2X_CONTROL_MODE ,0xFF); //set GPIO2X to Output function
this->Write_Byte(F75111_INTERNAL_ADDR,F75111_CONFIGURATION, 0x03); //Enable WDT OUT function
}
Set output value
