Introduction F81966 DIO

Image:F81966_Linux_help.png

  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

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);

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;
