LariSan Posted October 16, 2014 Share Posted October 16, 2014 Thank you so much for sending that over!I added your tutorial to the Max32 reference wiki and have asked someone to take a look at it.https://reference.digilentinc.com/chipkit_max32:refmanual#is_there_any_issue_with_using_the_pickit3_with_the_max32 Link to comment Share on other sites More sharing options...
Cristian.Fatu Posted January 15, 2015 Share Posted January 15, 2015 I post here the answer we gave when you announced us about this: There are some complex and historical design issues about the RTS / DTR and the cap. This is all part of the auto reset circuit. Originally RTS was part of that circuit and originally we loaded that 100 ohm resistor. Later we determined that hooking up RTS created problems it was just more reliable to remove the 100 ohm resistor. You will see on newer boards we do not connect RTS. DTR is critical to the auto reset functionality and is required for the proper operation of the board. Link to comment Share on other sites More sharing options...
