I am developing an application using Processor Expert. I am planning to use SPI to send and receive characters.
While choosing a bean for SPI communication i found two beans "Init_SPI" and "SW_SPI". When i looked into both of the beans thorughly I found out that "Init_SP"I bean initializes SPI and requires you to implement the interrupt handler, where as "SW_SPI" bean provides "Send_Char"/"Recv_Char" menthods to send/receive.
Do i need to use both of the beans or just use "SW_SPI" bean?
Thanks in advance
