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

F81966_DLL_API bool  F81966_LPC_Init(pF81966_status status);

F81966_DLL_API BYTE  F81966_LPC_Digital_Read_LOW();
F81966_DLL_API void  F81966_LPC_Digital_Write_LOW(BYTE byteValue);
F81966_DLL_API BYTE  F81966_LPC_Digital_Read_HIGH();
F81966_DLL_API void  F81966_LPC_Digital_Write_HIGH(BYTE byteValue);

F81966_DLL_API void  F81966_LPC_Set_WDT_Enable(BYTE byteValue);
F81966_DLL_API void  F81966_LPC_Set_WDT_Disable();

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();
