i'd like to get rid of the software reset, in ordner to not reseting the arduino everytime when opening an serial port or restarting the machine.
My main problem is, that the arduino should be running independently and just once in while i want to see wht's going on (so, no serial proxy).
now, does it make sense to just cut the 100 nf capacitor? I mean the DTR just seems to be used for resetting.
If so, where can if find it on the board? The datasheet of the FT232RL and the Arduino schematic do look slitly different, so i'm not sure where to cut...
yeah i know that... but i need it this way. but, do you know, which one it is? i don't really get a clue out of the arduino schematic. according to the datasheet it should be pin number two:
but i'm not really shure, as in the arduino schematic (which is the same as the picture below) it is located on a different place. any idea?
If you look at the board directly next to the USB jack, there is a silkscreen legend reading "RESET-EN." There are two solder blobs near the R of this legend. Between the two solder blobs in this photo is an electrical trace on the board. If you use a sharp knife, it seems like you can cut that trace to disable the DTR RESET behavior.
However, the schematic shows that solder-jumper ("RESET-EN") but also a signal bypass right next to it! Wonder why the schematic shows that, unless that's just a way to show that the jumper is "closed" by default, and both lines are seen as the same net in a circuit simulator.
wow, nice...thanks for that. i just think i forgot to mention, that i use the diecimila. at this one, this practical reset unfortunatelly diesn't exist. got an idea where i can find it there?
