Part Number: USB-TO-GPIO
I purchased one USB-to-GPIO to develop the I2C slave product.
Then the adapter was connected to the laptop (windows10 64bit). It could be showed in the device list as the "USB input device". The LED was illuminated.
and I used the "USB Interface Adapter GUI-v1.10" to connect the USB-to-GPIO.
But it could not to be do any operations.
e.g. When I clicked the pull-up resistors setting as 2.2kohm, it said " error setting resistor values".
When I want to send any bytes on the bus, but there is no signals changed on the bus. and the ACK/NACK shows "ERROR".
Could you help to solve this? What's wrong with my operations?
