Other Parts Discussed in Thread: C2000WARE

Hi,

I was trying to interface 4 Rows and 3 Columns keypad with the TMS320F28069M launchpad, if any can help with example codes or reference design, it will be of great help.

Thank you.

Hi Rahul,

There are no examples specially for keypad interface. You can develop using the base GPIO example code available in C2000ware.

Rahul,

Gautaum's suggestion is correct, the best place to look will be C2000Ware.

If your keypad is a basic matrix of switches then look at the GPIO examples, if your keypad is more complex and uses a communication protocol like SPI then I would recommend you look at those examples!

Regards,
Cody
