5. AxConfigGPIO(): Set GPIO configuration to input or output. If GPIO0

is digital input and GPIO1~7 are digital outputs, the GPIO1[0] value

will be 0x01.

Function BOOL AxConfigGPIO(byte GPIO1[], byte GPIO2[],

byte GPIO3[], byte GPIO4[]);

Arguments All GPIO configuration values for setting are placed in

four 1-byte arrays:

GPIO1[]: The 1-byte array for GPIO0~7 configuration.

GPIO2[]: The 1-byte array for GPIO8~15 configuration.

GPIO3[]: The 1-byte array for GPIO16~23 configuration.

GPIO4[]: The 1-byte array for GPIO24~31 configuration.

Return TRUE: No error.

FALSE: Function fails.

6. AxSetDO() : Set digital output status. If GPIO0 is set to High, the

SetDO1[0] value will be 0x01.

Function BOOL AxSetDO(byteSetDO1[], byte SetDO2[], byte

SetDO3[], byte SetDO4[]);

Arguments All digital output values for setting are placed in four 1-

byte arrays:

SetDO1[]: The 1-byte array for GPIO0~7 output status.

SetDO2[]: The 1-byte array for GPIO8~15 output status.

SetDO3[]: The 1-byte array for GPIO16~23 output

status.

SetDO4[]: The 1-byte array for GPIO24~31 output

status.

Return TRUE: No error.

FALSE: Function fails.

7. AxGetDI(): Get digital input status. If GPIO0 read back is High, the

ReadDI1[0] value will be 0x01.

Function BOOL AxGetDI(byte ReadDI1[], byte ReadDI2[], byte

ReadDI3[], byte ReadDI4[]);

Arguments All digital input values read back are placed in four 1-

byte arrays:

ReadDI1[]: The 1-byte array for GPIO0~7 input status.

ReadDI2[]: The 1-byte array for GPIO8~15 input status.

ReadDI3[]: The 1-byte array for GPIO16~23 input

status.

ReadDI4[]: The 1-byte array for GPIO24~31 input

status.

Return TRUE: No error.

FALSE: Function fails.

Connector Description

CN1~CN4 Digital I/O Connectors

Digital I/O Connectors (CN1~CN4)

CN1~CN4 are JST S10B-PHD-S-S, 2x5-pin p=2.0mm Dip connectors for

digital I/O interface. The AX92904 is equipped with four 8-bit digital I/O

connectors that meet requirements for a system customary automation

control. These digital I/O signals are from two 16-bit PCA9535:

CN1/CN2/CN3/CN4:

Note: Please contact your local vendors if any damaged or missing items. DO

NOT apply power to the module if there is any damaged component.

Jumper Setting

Before applying power to AX92904, please make sure all jumper(s) are in

factory default positions.

Programming Guide

A set of application programming interface (AxDIO32 DLL) functions are

released for users to access/control hardware. With these API functions,

users can more easily design their own software.

Note: To run the accompanied demo program, make sure that .Net framework

3.5 is installed on your operating system. Also copy AxDIO32.dll,

AxWIO32.dll, AXWIO32.sys and DIO_for_AX92904 files to the same

folder.

Description of eachAPI function is given as follows:

1. AxInit(): Initiates AxWIO.

Function BOOL AxInit();

Arguments None.

Return TRUE: No error.

FALSE: Function fails.

2. AxClose(): Terminate AxWIO.

Function BOOL AxClose();

Arguments None.

Return TRUE: No error.

FALSE: Function fails.

3. AxInitGPIO() : Set GPIO registers to default value.

Function BOOL AxInitGPIO();

Arguments None.

Return TRUE: No error.

FALSE: Function fails.

4. AxGetConfigGPIO(): Get GPIO configuration (as digital input or

digital output)

Function BOOL AxGetConfigGPIO(byte GPIO1[], byte

GPIO2[], byte GPIO3[], byte GPIO4[]);

Arguments All GPIO configuration values read back are placed in

four 1-byte arrays:

GPIO1[]: The 1-byte array for GPIO0~7 configuration.

GPIO2[]: The 1-byte array for GPIO8~15 configuration.

GPIO3[]: The 1-byte array for GPIO16~23 configuration.

GPIO4[]: The 1-byte array for GPIO24~31 configuration.

Return TRUE: No error.

FALSE: Function fails.
