Well i have been trying to program my 3pi Robot on my mac. And am running into issues. I am trying to do it through the Arduino IDE. In configuring it, i got through every step but when selecting the Serial port in the Arduino IDE, there is no COM port.

Best app for mac pro to record video. The easiest way to record video on your Mac is with the built-in QuickTime app. Open your Applications folder to find QuickTime. Once it's open, go to File > New Screen Recording and then click the Record button. Need to capture your Mac's screen? Here are the best apps for capturing your screen and creating video screencasts on macOS. We’ve rounded up the best screen recorders for Mac to help you decide.

And i am assuming that it is the USB orangutang is installed correctly, but i am not 100% sure. I am using the USB port but am getting an error.

I will post the error as soon as i get back to it, ive had to reconfigure my Arduino a few times for different projects. Edit: Note, I had the PGM02B, not the PGM03A I wanted to take some time to share some of the things I encountered when attempting to use the drivers I downloaded. I’m running Mac OS X 10.6.3, 64-Bit. I started off with the drivers from here: I found that the drivers were not being loaded on my system.

I checked out to see if the drivers were loaded by using: from the OS X Terminal. If you see “/dev/tty.Pololu” everything is installed, if you don’t then you are probably seeing what I was.

Some further investigation into the error console lead me to find this: May 15 21:53:31 Christopher-MacBook-Pro com.apple.kextd[10]: Can't read info dictionary for Pololu.kext: IOCFUnserialize: syntax error near line 3. May 15 21:53:58 Christopher-MacBook-Pro com.apple.kextcache[582]: Can't read info dictionary for Pololu.kext: IOCFUnserialize: syntax error near line 3. Some hunting around I actually tracked down and opened the plist located in the Pololu kernel extension and found that it was not properly formatted.

Here’s what I found in the driver’s Info.plist: [code] [/code] A proper plist should start with this: [code] [/code] For some reason, the driver wasn’t properly formatted and had escaped quotation marks in the XML file, and when OS X attempts to read the extension, fails because of the format. I found that I could actually fix the kext. Here are the steps I performed, unfortunately they’re all on the command line: sudo -i cd /System/Library/Extensions/Pololu.kext/Contents sed 's/ '/ '/g' Info.plist > tmp && mv tmp Info.plist cd././ kextload Pololu.kext/ logout The idea of the commands here are to Switch to root so we can actually change the PList without errors, do a Search and Replace on the PList and fix the escaped quotes, then load the kernel module.

Then logout of the root session. Hope the original poster hasn’t given up all hope and comes back to this thread. If not, hopefully someone else will stumble upon this fix. Who ever at Pololu made the drivers could easily fix this problem. Hello Ben, The CP2102 drivers available from your website are customized in some way from the default Silicon Labs drivers. I think they’re built with a custom installer and using your own PID for the USB driver.

Also they’re built with your manufacturing information in drivers, not Silicon Labs. [quote]Pololu Driver version V1.02.2 CFBundleExecutable Pololu CFBundleIdentifier com.MCCI.Pololu Snip idProduct 32827 idVendor 4292 [/quote] Someone has done some customization to the drivers, however, they don’t work properly anymore.

Open source support: www.nodemcu.com; R2 version had CP2102 USB-TTL instead, larger current support, slim board can put on breadboard. Support windows 8.1 by CP2102, and support ESPlorer. I have a problem with the USB TTY console which is never working in any baud rate no matter I install the cp2102 driver or not. A development kit for NodeMCU firmware.
