[Samuel Mello Medeiros]

Salve atutti!
Volevo fare un semplice menu (sei tasti mi batono) che come funzione principare serebbe quella di far partire al click un programma python, piu precisamente un programma per scattare foto. Esempio; se clico nel menu "Foto color 200 asa", lui fara partire il programa piton preconfigurato con il color 200 asa, e cosi via 400 asa, 800 ecc.
ho trvato questo script python (pitftmenu) che in origine era per un TFT 2.8 e quindi ho cercato di adattarlo al mio piccolo 2.4.
Vi inserisco lo script e se qualcuno mi sa dire che comando devo inserire per far si che mi apra il programma nel mio caso di test si chiama "camera.matrix.py" si apra, sarei grato.

come devo scrivere il comando?

if number == 6:
# Camera Matrix
pygame.quit()
##startx only works when we don't use subprocess here, don't know why
os.execvp("python", ["python", home/pi/camera-matrix/camera-matrix.py])
sys.exit()

AIUTO!!!
