'How to use this Demo Application one F75111 two F75111 Attention Please:You must be install vcredist_x86.exe when first time you run the F75111_DIO.exe DEMO AP,The vcredist_x86.exe include all required DLL file. 1. Press the "Start" button to test DIO function 2. Press the "Enable" button to test WDT function 3. Press the "Disable" button to disable WDT 4. Check the "Enable Loop" box and press "Enable" to do WDT loop test 5. Press "Install WDT" to set the system to autorun this application when booting, press again to remove this application when booting. 6. If WDT enable, system icon will be . if disable, system icon will be p.s. f75111 send "F75111_SetWDTEnable(BYTE byteTimer)" including a parameter "timer", if there's no disable signal (F75111_SetWDTDisable()) to stop it before timer countdown to 0, System will reboot. if there's disable signal received, resent Enable WDT signal, for a loop to prevent from reboot 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() Enable/Disable WDT Enable : F75111_SetWDTEnable (BYTE byteTimer) Disable: F75111_SetWDTDisable () 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,GPIO3X_CONTROL_MODE ,0x00); //set GPIO3X 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 void F75111::InterDigitalOutput(BYTE byteValue) { BYTE byteData = 0; byteData = (byteData & 0x01 )?
