I have a Freedom KE02 board I am using as a programmer for a stand-alone KE02 system. I am using J7 as the programming interface, after disconnecting the dataline from the on-board KE02.
I have to use the stand-alone system at 5V. In order to keep using the Freedom board while powered up at 5V, I will disconnect V3.3 from J7. Should I put a 1KOhm resistor in line with the SWD_DIO or CLK lines? I am using TXD and RXD with 1KOhm resistors in line with those signals.
Please help, I also use FreeMaster so having the stand-alone and the Freedom boards connected while operating is required. I just don't want to hurt anything.
