1. Suppose i am having a spi master and spi slave (both are lpc2468 based)what is the procedure to read some bytes from a particular address of spi slave i.e what we all need to do like send some commands, data, some opcodes. how is request sent to read particular number of bytes
2.I went trough arduino website (arduino.cc/.../SPIEEPROM) and studied about spi communication between master and eeprom acting as slave.I came across opcodes over there but i was not able to understand what basically opcodes are and what is there significance.
