Hello everybody, I'm using my recently Paspberry Pi board in some experiments, this time was my arduino uno connecting via serial UART to access my application Rpi alert by minicom.
Some wires soldered directly on the pins 5v Power, Ground, GPIO 14 (TXD) and GPIO 15 (RXD). The circuit functioned as expected. But when I removed the wires and turned again Rpi images appeared as if ouvesse interference or noise on the screen.
Post this video with more details about the problem, the image is not very good because I filmed using my phone.
You can see the best noise in the upper left of the screen where the logo appears Raspberry Pi.
Here is the link to the video: http://youtu.be/0OpHKJElDZk
If anyone knows the problem please let me know.
