I was using EmbedXCode (v1.39) with my Arduino Pro-Mini 3.3v and it was having trouble finding the serial port. Uploading would fail right away. So I ran "ls /dev/tty.usb*' in terminal and in the mini 3volt xcconfig file I changed
BOARD_PORT = /dev/tty.usbmodem*
BOARD_PORT = /dev/tty.usbserial-AH01PAW8
This solved the problem. Is there a way to make EmbedXcode work better with usbmodem*? I gather the whole serial port thing is a bit tricky.
Also, I noticed that a few times I uploaded the sketch and Xcode said it was successful but the changes I made didn't take, so the program really didn't upload - strange. I did see the Tx and Rx LEDs blink rapidly. This happened when the Target was "Upload", but sometimes it worked properly on Upload. I changed the target to "Fast" and the program was actually uploaded, but it may have been a coincidence that it worked with the Fast target.
I'm running on iMac with Mavericks and using Adafruit FTDI Friend
. This morning I installed EmbedXcode v1.41 and had the same issue with the serial port.
