Hi,

Is is not possible to readout the status of a digital output ?
It’s possible to set & clear the output, but it is not possible to readout the current state.
This means that if you lost the connection with the board, you cannot check the output status again, unless you use the digital inputs to monitor the outputs.

Is there no call check the value of an output (the value must be present in the board, so it’s strange that you cannot read it out) ?

I’ve used the board to control & change the status of some items by a web interface in PHP.

Thx.

Yes, you are right - this kind of "readback " function is missing from the K8055 firmware.
To be sure about the output status you have to update it from your software after every loss of connection to the K8055…
