some lcd & keypads use serial commuication
so which data transfer yo use really depends on the hardware you selected

Hi there,

I want to connect the DSP with a LCD and a keypad.
When switched on the user is asked about certain parameters, which he can feed into, using the keypad. The collected data has to be transmitted to the DSP and stored in the variables until a new input has been made.
Does anyone know how I could implement that?
Which Hardware could I use and which interface should I use for data transfer (e.g. CAN-BUS)?

Thanks for your help, Greetings
