Try one of the following possibilities:

\version "2.16.1"
progChordsI = \chordmode { f1*7 c1 }
progChordsII = \chordmode { \set chordChanges = ##t \repeat unfold 7 { f1 } c1 }
<<
\new ChordNames \progChordsI
\new Staff { \repeat unfold 7 { f'1 } c'' }
\new ChordNames \progChordsII
\new Staff { \repeat unfold 7 { f'1 } c'' }
>>
