Advantech PCM-9588 user manual Test Write Multiple Output Pins, 4.5 I2C, Read a byte, Write a byte

!Test Write Multiple Output Pins

–Click the radio button- Multiple-Pins.

–Key in the pin number from ‘0x01’ to ‘0x0F’ to choose the multiple pin num- bers to write the value of the output pin. The pin numbers are ordered bit- wise, i.e. bit 0 stands for GPIO 0, bit 1 stands for GPIO 1, etc. For example, if you want to write pin 0, 1, and 3, the pin numbers should be ‘0x0B’.

–Key in the value in (R/W) Result field from ‘0x01’ to ‘0x0F’ to write the value of the output pin. The pin numbers are ordered bitwise, i.e. bit 0 stands for GPIO 0, bit 1 stands for GPIO 1, etc. For example, if you want to set pin 0 and 1 high, 3 to low, the pin number should be ‘0x0B’, and then you should key in the value ‘0x0A’ to write.

–Click the WRITE GPIO DATA button to write the GPIO output pins.

4.3.4.5I2C

When the application is executed, you can read or write a byte of data through I2C devices. All data must be read or written in hexadecimal system.

!Read a byte

–Key in the slave device address in Slave address field.

–Key in the register offset in Register Offset field.

–Click the READ A BYTE button and then a byte of data from the device will be shown on the Result field.

!Write a byte

–Key in the slave device address in Slave address field.

–Key in the register offset in Register Offset field.

–Key in the desirous of data in Result field to write to the device.

–Click the WRITE A BYTE button and then the data will be written to the device through I2C.
