Hi, and thank you for your quick reply. Much appreciated. How do I replace OpenCat (1.0) which you installed on my Bittle several days ago with the new OpenCat 2.0 created just yesterday so Bittle “can automatically switch between body and ball detection with a whole-body motion of the robot.”? IMPORTANT: Please provide steps I must take to accomplish this update Since I am a novice and don’t yet “speak” coding language, please provide steps that are clear in layman’s language. I’m trying to learn, but it’s a slow process.

I was gone from my computer for past three hours, therefore Lark access codes expired. Please send again. Thanx.

Lark won't allow me to download the driver. They say I must request permission from you. I have added you to my Contact file.

I have the Bittle connected to my Mac’s USB port. RED LED on USB Uploader board, BLUE LED on the NyBoard. Under Arduino “Tools” menu, mine is reading different than shown in figure in 4.2.3. Perhaps a newer version? 1. I am able to select “Arduino Uno”, just don’t have the intermediate step (don’t have choice Arduino AVR Boards or NyBoard-avr) as shown in paragraph 4.23. I assume this is OK. See my Fig 1. 2. However, how do I select a new port? I only have ports for iPad and Bluetooth showing. Do I add in preference? If so, how? Fig 2, 3 & 4. I opened OpenCat and found only (Fig 5) #ifdef BITTLE PTLF("Bittle”); Thank you again so much for taking time to get me started on this project.

Thanks again for your help. Much appreciated. Hopefully I will have no more silly problems.

Your heading being GREEN threw me off. Mine is just plain. Perhaps change in OS ?

Great. I just didn't notice the heading changing on m y 27" screen. 谢谢你

My error. Sorry. I clicked on the green area for OpenCat and found the heading on the Mac.

Sorry for being confused, but where do I find the green Arduino Window. I have only down loaded the two referenced earlier. Clicking on the green in these two downloads gives nothing. Is the Arduino window (you are referencing) on the Nyboard or a download from the Internet?

That's my problem. How do I get into the Arduino window. I am apparently missing something basic. Where is Arduino window?

Thank you for your quick reply. I am on a Mac (OS 10.12.6) and not seeing the heading referenced in your Bittle User Manual paragraph 4.2.3 - Arduino/File/Edit/Sketch/Tools/Help. I suspect I am missing a download. I downloaded 1) Arduino IDE and 2) OpenCat. Neither have the above heading shown on my Mac. What download am I missing, please?
