Introduction Command List

 “-h”: Show help menu about DLL function.
 “-exit”: Exit sample program.
 “-i”: Initial GPIO module.
 “-f”: Free GPIO module.
 “-check”: Check F81966 module chip exist or not.
 “-c”: CIO port. Support CIO port is defined in Motherboard spec.
 “-sd”: Setup GPIO pin status is DI or DO in CIO port.
 “-so”: Send DO signal once to trigger pin to high or low in CIO port.
 “-gd”: Get current GPIO pin status is DI or DO in CIO port.
 “-go”: Get current DO pin trigger status is high or low in CIO port.
 “-gi”: Receive current DI pin status.
 “-u”: Setup WDT time unit. Value = 0: Second; Value = 1: Minute.
 “-we”: Start WDT function and setup countdown seconds.
 “-wd”: Stop WDT function.
 “-wt”: Query WDT countdown remaining time.

F81966 DIO with CIO116_B

CN-DI_0A(white_red) to CN-DO_8A(white_red)、CN-DI_1A(green) to CN-DO_9A(green)、CN-DI_2A(yellow) to CN-DO_AA(yellow)、CN-DI_3A(orange) to CN-DO_BA(orange)、
CN-DI_4A(red) to CN-DO_CA(red)、CN-DI_5A(brown) to CN-DO_DA(brown)、CN-DI_6A(black) to CN-DO_EA(black)、CN-DI_7A(white) to CN-DO_FA(white).
GND and +VCC connect to power.

F81966 DIO direct connect

Using 2I130HW to example how to connect.
DI-0(yellow) to DO-0(yellow)、DI-1(black) to DO-1(black)、DI-2(orange) to DO-2(orange)、DI-3(blue) to DO-3(blue). GND and +5V are empty.

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();
