Compile Problem with PSoC Express when a Tach Timer Module is Present

Version 1
    Question: When a Tach Timer Module is present in PSoC Express, the project won't compile. There is an error generated pointing to Tach Timer.



     This is a known issue with PSoC Express 2.2. To solve the problem, start a build and unassign all the pins from the chip. Then reassign the pins starting with the tach pins, followed by all other pins. Finally, complete the build.
