Posted on February 25, 2012 at 15:16Hi good people,
I use my MCU as an SPI slave module.
application description:
It is connected to an SPI generator which sends 8 different words(each word is 16 clks) repeatedly. (1Mhz) : 0x0001, 0x0002,..., 0x0008,0x001,0x0002,...
every time i receive 0x0002 , i need to send on the next cycle 0x0800
every time i receive 0x0003 , i need to send on the next cycle 0x0400
My system clock is 24MHZ so i want the application to be as fast as it can.
Can you give me a hint how can i implement it (use IRQs , polling ? )
some example code can really help me..
thanx! :)
