Hello,
I have a problem with BBB + BB-View + LCD7.
OS: TI-SDK from element14 site
HW: BBB PCD Rev B4, Element 14 BB-View cape, 7 LCD LCDX000-70T
1. Colors are strange. Looks like not enough color depth or wrong blue
color intencity
2. When I place my hand near the cable, didn't even touching
I've reconnected internal LCD cable. Blue color appeared and blue noise
disappeared. But there is still not enough color depth.

Adam,
If your issue is a low frame rate coming from the PS3Eye, I have written
about this problem here http://blog.lemoneerlabs.com/post/BBB-webcams
To make a long story short, the transfer method the PS3Eye uses to transfer
data over USB doesn't work on the BBB at high frame rates and/or high
After some further testing I can clarify the behavior of the I2C-bus:
When I manually access the I2C-dev nothing happens, SDA and SCL keep 3.3V

When I use the command i2cdetect -y -r 1 the SCL gets the typical
clock-look with about 4us high and low, except for its not going

Hi, sorry for not responding when I said.
The PCB's have now arrived from the manufacturer and the parts have arrived
