– Key in the value either '0' or '1' in (R/W) Result field to write the
output pin you chose above step.
– Click the WRITE GPIO DATA button to write the GPIO output pin.
n
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 numbers 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 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.
I2C
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.
n
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.
n
Write a byte
– Key in the slave device address in Slave address field.
