Hello, we have updated the Data Sheet for the MegaProLogic. A table was added that maps the signals from the connector pins to the I/O pins on the CPLD. 

The schematic is your most accurate source for understanding how the headers correspond to pins and signal names. If you do not have the schematic, contact the manufacturer or distributor to request it.

Could you clarify which specific documentation or resources you are using? Additionally, have you checked if there are multiple versions or revisions of the documentation, which might explain the differences in the pin names?

To learn which headers go with which pins and which signals are what they are, go to the diagram. You should get in touch with the distributor or manufacturer to ask for the basketball stars schematic if you do not have it on hand.

Ensure that you have the latest version of the board's documentation. Manufacturers sometimes update pin mappings, so look for a newer revision of the datasheet Block Blast Puzzle or user manual on the manufacturer's website.

I have had this happen with other boards – sometimes the documentation is missing or outdated. Have you tried tracing back through the schematic or using a multimeter to determine what the pins do? Alternatively, check the community to see if anyone has worked with the EPT-5M57-AP-M4 That's Not My Neighbor and has additional information. If you find a solution, please share. I’m interested!
