1. Make sure the host mode switch is in the "A" position. 2. Make sure you're using a standard micro-B USB cable (i.e. do NOT use the provided red cable when connecting to a PC). On Thu, Dec 17, 2015 at 5:37 PM, JooeeB wrote: > I plug ioio to the computer but

Re: Relay control problem with IOIO

First, if you're saying that changing the software to use the pins in open drain mode made things start working, it leads me to believe there might be an internal pull-up to at least 5V on the relay, which might damage the pins, depending on how strong it is. Second, there's no such thing as a

Re: Two-wheel-mobile robots! Bluetooth or USB? This is the question!

Depending on how you wrote the code, your control algorithm might be sensitive to latency (much higher on BT, ~20ms vs ~1ms) and/or jitter (much higher on BT). As for the cycle period, it is up to you to decide it, it shouldn't depend on the connection type. If you want to change the behavior

Re: sequencer library & stepper motor

The best sources of information are: - The wiki page: https://github.com/ytai/ioio/wiki/Motor-control - Javadocs of the Sequencer class (available in HTML form in the software bundle). If you insist on a real-life code example, here's one, but probably not as simple as you had hoped:

Re: IOIO MANAGER

No. It is a little confusing. IOIO Manager cannot be used on newer ( >= 4.1) Android devices, when used for upgrading application firmware for old (v1, mint) IOIOs. I *can*, however, be used to drive a IOIO to be used as a programmer for another IOIO on any Android version. On Sat, Nov 21, 2015

Re: IOIO MANAGER

NO NEED TO SHOUT :) A few things to note: - Upgrading the firmware of old IOIOs (including the Mint) with IOIO Manager only works in Android < 4.1. In other words, you have to get an OLDER phone for that to work. - You seem to have some misconceptions about how IOIO Manager is

Re: IOIO-OTG PC Application Question

It's surprising that this version was already there, I wasn't aware that SparkFun started shipping with this firmware already. In either case, is the switch on the IOIO in the "A" position? Are you using a standard USB A <=> micro-B to connect the IOIO to the PC? If the answer to both questions is

Re: IOIO-OTG PC Application Question

You're connecting it wrong. Just use a standard micro B USB cable to the IOIO. Do not use the red adapter. It is for connecting to Android. On Nov 19, 2015 6:43 PM, "ThePie" wrote: > Actually I forgot to mention that right when I got it I ended up flashing > it so I am
