I currently build a Blinking Tutorial based on the Documentation and map it to the FORTE running on the Raspberry Pi.

Through deployment, I can see that the IO pin has been enabled, but when I use a voltmeter to monitor the actual IO voltage output, it does not seem to change.

I don't know what went wrong. There are some screenshots of my program running instructions in the attachment.Could anyone please help me with some modifications or debugging ideas ? I want to find out if there are some details that I haven't noticed.

Very grateful

HI,

at the first look I see that you are sending to the QX and IX blocks a lot of input events. This should in theory not be problematic, but I'm not sure. What it is definitely doing is masking the response to your REQ for setting the output. The correct way would be to first have IX and QX initiliased and use the INITO of your QX block to start your E_CYCLE.

I hope this helps.
