The IOIO can work as either a device or host, depending on which side of the USB cable is connected to it. You'd need to include the IOIOLibAndroidDevice library in your project. It can also work as a USB device with a PC app in a similar manner. On Thu, Apr 30, 2020, 09:38 Christian Gutierrez

I think you might be somewhat misusing the term OTG. USB OTG has to do with the ability of a device to switch between being a host on the USB bus to bring a device, based on which side of the cable it is connected to. Since all phones used to be only devices, manufacturers started using the term

You won't be able to charge the phone if you're using the IOIO in device mode, since it is always the host that supplies power to the device and not the other way around. When you say "OTG" I'm assuming you mean that the phone is the host and the IOIO is the device. Otherwise, I don't see a reason

Analog samples get pushed from the IOIO to the Android at 1kHz (one sample every 1ms). So if you use getVoltage(), whatever sample you're getting is only a few milliseconds old (since there's some latency too). I'm guessing that for pH measurements this is completely insignificant. The *Sync

There's already a b4a library for IOIO. Maybe use that? On Jun 17, 2016 6:17 AM, "István Rostás" wrote: > Thank you for reply. I red Sparkfun and build my own ioiolibandroid.jar. > Then I extracted the non-activity part of the HelloIOIO and IOIOService > example app to

There are maven targets for the libraries. Please refer to the wiki and or example apps. Can you please test the precompiled apps before proceeding to you own built ones? On Jun 16, 2016 15:58, "Daniel Buchanan" wrote: > Hi Ytai, > > It does show up as /dev/IOIO0,

Re: New IOIO-OTG won't connect to existing software on Linux

Is the new board appearing as a /dev/IOIOx device? Are you using the exact same jar with both versions? What's the deal with the undefined IOIOLib version? There have been some changes in the library that may have caused this problem, but I cannot see how the firmware version is related. On Jun

I don't know this app at all, but from a quick scan it seems like the IOIO-related stuff takes place in: https://github.com/akexorcist/IOIO-CameraRobot/blob/master/app/src/main/java/app/akexorcist/ioiocamerarobot/ioio/IOIOControllerActivity.java#L329 You'd need to open PwmOutput on whatever pin
