Hi,
I am using in my project the shield on the link below and it works perfectly.
http://www.ghielectronics.com/catalog/product/289
But when I put a InputPort button on the digital port for example 11 the following error occurs:
#### Exception System.InvalidOperationException - CLR_E_INVALID_OPERATION (1) ####
#### Message:
#### Microsoft.SPOT.Hardware.Port::ReservePin [IP: 0000] ####
#### Microsoft.SPOT.Hardware.SPI::.ctor [IP: 0036] ####
#### GHIElectronics.NETMF.FEZ.Shields.MusicShield::.ctor [IP: 0078] ####
#### ProjetoCA002.Program::Main [IP: 001a] ####
A first chance exception of type 'System.InvalidOperationException' occurred in Microsoft.SPOT.Hardware.dll
Erro: Exception was thrown: System.InvalidOperationException
I am using the class as my driver MusicShield:

If I take the shield and connect directly to my FEZ Domino the buttons work perfectly.
Important also am using a 16x2 LCD display with backlight.
Thanks.
