SPI max distance


I have a PIC16F877 µController, connected via SPI to a MCP23S17 and the last it connected to an keypad and LCD screen, the distance between the µController and the MCP integrated circuit is 5m. My question is will it work or not? And if it does not work how can I resolve this problem. Is there a solution (like a Integrated Circuit or a trick)?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
