Hello all,

   

Greetings for the day.

   

       I'm working with the PSoC 1, device CY8C20x34-12

   

It is a 8-bit micro-controller, I have configured 8 Buttons (+8 LED's) using this uC; my question is Can I configure more than 8 Buttons using this uC.

   

it has 28 I/O's, 7required for (4- 2VDD, VSS, XRES & 3- 2EzI2Cs, Extr. Cap) & remaining available.

   

If it is possible please guide me on it, also if you have some sample codes for it do forward.

   

Thanks & Regards-

   

Amit
