Howdy everybody! School and work has had me snowed under, I am finally getting back to getting a bit further into the MSP's For a 4-20mA signal input to a MSP430 2 wire signal I know I need to setup the ADC to read the signal, I found some of the TI documentation on setting it up but I think I am more confused now than I was when I started. If I have the transmitter running at 3.3 volts I can go right to the MSP with it right? If I need to run higher voltages I can use an OP amp to work around the higher voltage level, or measure the V difference across the transmitter? Any ideas or direction to point me in? Thanks guys! I plan on using the signal in to generate a PWM output signal
