Hi all, I am new to this discussion , but saw the post thought I could contribute my findings. I have been using MIT App Inventor2 with IOIO-OTG for about 3 months with pretty good results. I also am old school but have done plenty of control programming using Basic, C++ and others, I also did not want to learn yet another language. I am building a stepper motor controlled robot with off the shelf parts.
He is still an infant, but I have him moving well with speed control, turning, reversing, and even running a pre-programmed pattern over Bluetooth from my Android to the on-board IOIO-otg. I am using a windows 7 development PC, logged into MIT AI2. On the Android I have loaded MIT AI2 companion app, IOIO Inventor, and of course G-Mail for downloading and installing my latest App revisions. Since the AI2 commands are limited to basic I/O, a big breakthrough for me was using the "Sound" command to drive the Stepper controllers speed... along with 2 digital Outputs 's ...1 to set direction, and 1 Enable the Stepper controller after the frequency stabilizes. I hope this helps get you started... Now, I could really use help with is understanding how to program the IOIO "sequencer" using AI2 . I seem to be able to send a "string variable" from AI2 to the IOIO, but I need to know ...is what to put in the string to set up multiple PWM channels....and then sequence them. Any help would be greatly appreciated. On Monday, May 25, 2015 at 8:26:17 AM UTC-4, joe el khoury wrote: > Dear Ytai, > > Is it possible to use app inventor for IOIO? It may save a lot of time.
