I try to understand how to use multiple SPI devices on a PIC18F4550.
I have read on the daisy chain using different chip select all on the same SPI BUS but i cant find any detail on how the data travel...
Example;
If i use a SD card as a data logger using the SPI and a EEPROM as a LCD buffer also SPI.
Can i use them simultaneously or i need to wait the previous chip select before sending another?
If the LCD buffer write and read all the time at full speed did i need to stop my buffer to send data to the SD card?
