Better use raspi-config to disable the console.Massi wrote:This should be a matter of:hansotten wrote:That is possible, once you manage to have Linux stop using it as console.
should i see something in the arduino ide when connected in this way?
because i tried (with no much committment, i admit) with a clone i had in my "box of toys" and could see only grayed out "serial port"..
True, the signals coming from the Arduino serial are +5v, a voltage divider may be enough to protect the RPi. The 3.3V from RPi to Arduino is no problem.jackokring wrote:Removing some /boot/cmdline.txt references, and a bit of raspi-config fiddling should free the serial. And you might need to disconnect the signals from the "atmel" TX and RX pins from the serial to USB chip. And pay attention to not connecting 5v to 3.3v maximum voltage pins.
So, this looks like a Wheezy, correct? Any idea what I can do to get the ch340 recognized on my system? I made sure to get the latest updates already.hansotten wrote:Linux raspberrypibplus 3.18.11+ #781 PREEMPT Tue Apr 21 18:02:18 BST 2015 armv6l GNU/Linux

Code: Select all
sudo modprobe ch341
