no42 Posted November 6, 2013 Posted November 6, 2013 If you use a "bus-pirate" you have to enable the pull up resistors (2K – 10K ohms) - maybe this is what your missing? Quote
Fira Posted November 6, 2013 Posted November 6, 2013 I had this problem too... are you using putty? check the "keyboard" options under "terminal". i *think* the one that worked for me was VT100+ although it may have been VT400 Quote
Soviet Posted November 7, 2013 Author Posted November 7, 2013 Just tried all the variations of keyboard options. No dice. Quote
Luisfer85 Posted January 3, 2014 Posted January 3, 2014 Hello. I have the same problem. I don´t understand the post of midnitesnake: If you use a "bus-pirate" you have to enable the pull up resistors (2K – 10K ohms) - maybe this is what your missing? Quote
