Introduction F81966 DIO

Image:F81966_Linux_help.jpg

  1. Use GET_CIO_INPUT to get the digital input data
  2. Use SET_CIO_OUTPUT_DATA to set digital output data
  3. Single bit setting can use SetCIOXBit0, SetCIOXBit1
  4. Read a single bit using GetCIOXBit
  5. Enable WDT and continuously reset WDT to ensure that the restart signal will not be triggered when the system is normal

libF81966.so Function 

bool F81966_OPEN();
void F81966_Init();

BYTE GET_CIO_INPUT(int CIO_Number);
BYTE GET_CIO_OUTPUT_DATA(int CIO_Number);
BYTE SET_CIO_OUTPUT_DATA(int CIO_Number, BYTE byteValue);

BYTE GetCIOXBit(int CIO_Number, BYTE bitPosition);
BYTE SetCIOXBit0(int CIO_Number,BYTE byteValue, BYTE bitPosition);
BYTE SetCIOXBit1(int CIO_Number,BYTE byteValue, BYTE bitPosition);

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

test_F81966 CIO Input/Ooutput

sample code 

Set CIO1 Digital Output all bit low
test_F81966 write 0xf;


Set CIO2  Digital Output all bit low
test_F81966 write 2 0x0;

Set CIO3 Digital Output all bit high
test_F81966 write 3 0xf;

Get CIO4 Digital Input 
test_F81966 read 4;


read bit position
test_F81966 getbit 1 1

write bit position
test_F81966 setbit 1 0 1

Watch Dog test

sample code
test_F81966 getbit 1 1 

Set WDT 10 sec
test_F81966 wdt enable 10;

Disable WDT
test_F81966 wdt disable;
