it is you who wrote all of this??!! well then, i do not want to waste any of your time,.. but would like to pay due compliments and congrats,.. it all looks very nice. well done. the program i am posting in regards to ,.. was not a scope generating a wave, but rather a list of the 40 pins and it was counting the electrons?? or thing (packets) being passed and i had high number happening, but then i ran "pintest" by Gordon Henderson and the the numbers came down,.. but first of all i had your program up and running in order to witness the change,.. i am just not seeing it anywhere. it is probably standard ware on this unit, but i am baffled as to which folder it is in and have searched many different times and names it could be,.. in an attempt to invoke the program. when i try to install from your site, my unit is saying i already have the latest,.. i just do not see where it is,.. i think,.. like with pintest i had to purge wiringpi and then install the one online in order for it to show up in a search.
