Introduction F81966 DIO

1. Start test Button,Send bits one by one and one by one receive
2. CIO116 mode for CIO116 module use
3. Set time countdown,If the end of the countdown, the trigger signal to reboot
4. Enable loop ，Continuously reset the WDT to ensure that when the system is normal, the restart signal will not be triggered

F81966_DLL Function

 bool F81966_OPEN();
 void F81966_Init();
 void F81966_LPC_Write(BYTE LDNData, BYTE reg, BYTE value);
 BYTE F81966_LPC_Read(BYTE LDNData, BYTE reg);
 void F81966_LPC_Digital_Write_LOW(BYTE byteValue);
 void F81966_LPC_Digital_Write_HIGH(BYTE byteValue);
 BYTE F81966_LPC_Digital_Read_LOW();
 BYTE F81966_LPC_Digital_Read_HIGH();
 void F81966_LPC_Set_WDT_Enable(BYTE byteValue);
 void F81966_LPC_Set_WDT_Disable();
 void EntryLPC();
 void ExitLPC();

Digital Input/Ooutput test

Note when using the following boards:2I110D
CIO1 needs to be controlled by CIO3


sample code

Set CIO1 CIO2 Digital Output all high
F81966_LPC_Digital_Write_LOW(256);

Set CIO1 CIO2 Digital Output all low
F81966_LPC_Digital_Write_LOW(0);

Set CIO1 Digital Output bit 4 high
F81966_LPC_Digital_Write_LOW(16);

Set CIO2 Digital Output bit 10 high
F81966_LPC_Digital_Write_HIGH(4);

Read Din
value = F81966_LPC_Digital_Read_LOW();

Watch Dog test

sample code

Set WDT 10 sec
F81966_LPC_Set_WDT_Enable(10);

Disable WDT
F81966_LPC_Set_WDT_Disable();
