Trying to find some easy(?) circuits for level shifting SPI from 1.8v master to 3.3v slave.
Currently I have some resistors based dividers, but it's not working that well. At the moment its running 0.5Mhz clock rate, but I would like to pump it up to 1Mhz at least if not up to 10Mhz. Resistor divers are out of question I believe?
