I have a 5v device sending data out on its Tx and I have to connect it to a micro's (MSP430) Rx which is 3.3v level. I tried using a simple resistive divider (5K and 10K) but behavior is erratic (sometimes works, sometimes does not, sometimes starts when you touch it...). What is a better way of doing this? Using a MOSFET?
