CMU cam not working
Hey everyone. I just bought a CMUcam1 which I am very excited about using, except that I can't even seem to get it working with the test java app from cmu.
I'm using Mac OS X, going through parallax's serial-USB converter (the FTDI chip). I wasn't sure which serial port to use, but I saw two ports in one of my programming apps:
/dev/tty.usbserial-A20e1xpS and /dev/cu.usbserial-A20e1xpS.
I honestly never used the 'cu' port, but I tried that one too because the main connection on the CMU camera is 'level shifted' serial, and it also has pins for tty (and I don't know what's what).
So I tried using both of those. When I use the tty one in the first window (that asks you what serial port to use), that window closes and then nothing happens.
When I try using the 'cu' one, the group of windows open, but the little console window gets stuck on "searching for camera" and never tells me it failed to find the camera.
There is no communication at all with the camera. The red led on the usb-serial converter nor the green led on the camera ever light up.
Has anyone had the same problem? Can anyone help me out?
(On an update, I tried this on my windows machine, and it worked but not like expected. I thought there was supposed to be a live camera feed, but I have to issue the DF command myself to get an image. And it updates the image REALLY slow, even though I have the baud rate set at 115200 for the com port)
