Dear all,
How to communicate At89c51rd2(Master) with At89c51rd2(Slave) using SPI protocol.I am using seperate pins for spi(not the dedicated pins of spi protocol).I am using 20 Mhz crystal for both and same power supply.How to read/write from master to slave?
regards, krishna
If you have placed yourself in a situation where you have to bit-bang the slave, go buy a "family size" bottle of aspirin
