Purpose
Guide the way to use GPIO control on JDIO1 in Windows and show the number for GPIO assignation.
1. The GPIO on JDIO1 is control by TCA9555 IC.
2. Follow the instruction from the link to download API and method to test GPIO on Windows.
GPIO API: https://webdownload.avalue.com.tw/wiki/OFT%20Series/Microsoft%20Windows/API/GPIO.zip
I2C TCA9555 Driver: https://www.avalue.com.tw/godownload.aspx?go=14282
3. It needs to prepare the loopback connector first, make the GPIO output port connect with the input port as below.
● Before change the value of gpio to hi, the voltage we measured is 0V.
● After change the value of gpio to hi, the voltage we measured is 5V.
