Programming serial gateway using a Mac..

[abagadol]

Hey everybody! I've tried searching the forums but cannot seem to find any sort of guidance on this issue. Im creating the Serial Gateway using Arduino sensors and have run into a programming issue.

Here is the link if your not familiar with the project: http://www.mysensors.org/build/serial_gateway#upload-the-serialusb-gateway-sketch

Ive managed to create the sensor however when I plug in the gateway to my Mac (running OS X 10.10) and run the arduino software to try and program the gateway I keep getting an error.... I have uninstalled and re-installed the software plugins but that doesn't seem to have worked. I will attach the screenshot below.

Does anybody know a workaround or the solution? (aside from buying a PC since that is out of budget)..

@abagadol Check the USB chip on the bottom of your nano, if the chip says FTDI it should work, if it is the CH340 chip, it won't work with the default Mac USB drivers. There are drivers for the CH340 but people have had a hard time getting them to work properly.

@Dwalt thank you for the info. Yes, mine does say ch340. Can you point me in the right direction? Or should I just order the other style nano?

Thanks!

@abagadol I found this post where the guy updated his drivers to make the CH340-chip nano work and he has links to win/linux and mac drivers. I had one of these nanos last winter and could not get the drivers to work on my mac but I had also just updated to yosemite and things were all haywire with my mac at the time. I still have the nano but have not used it. Good luck.

Got them working on my mac by adding the drivers from here

I´ve used the same driver on win7 and it works too.

@hek I seem to be struggling with this, I downloaded the driver you posted, Did a full reboot to the computer and the Mac still doesn't recognize the CH340. What am I missing?

@abagadol

Sorry, can't help you here. Suggest googling on the board name.
