Re: Need help! what should i use??

When you say you're attaching your LED "straight to" a 9V or 12V battery, do you mean that literally? Most LEDs will need a current limiting resistor in series, or they will be destroyed pretty quickly. Google "LED current limiting resistor" if you're unfamiliar with this requirement. Francesca's p...

Re: Need help! what should i use??

Hi Francesca, Sounds like a good project to work on! another option is using the Leo stick as its the right size but problem is that its power source is USB which could be helpful if i could attach a rechargeable battery so when usb is connected it charges the battery and when disconnected the light...

Re: Nothing happening over serial (everything else okay!)

Hi Matt, Glad to hear you got it working. That is indeed very odd, the fact that it's successfully enumerating as a USB serial device should rule out most low-level hardware or signalling problems. However the fix points directly to something like that. I'm not familiar with how OS X numbers serial ...

Re: Nothing happening over serial (everything else okay!)

Hi mafro, Sorry to hear it's not working for you. Are you using the latest board profile (3.3)? Do you have "Freetronics LeoStick V1" set under Tools -> Board in the Arduino IDE? I tried the sketch on my V1 and it worked, but it only compiled after I removed this section: while (!Serial) { ; // wait...

Re: A working avrdude config for LeoStick

What wintrmute gives should work great for v1 bootloaders . For v2, the avrdude line should be: avrdude -patmega32u4 -cavr109 -P<port> -b57600 -Uflash:w:myprogram.hex:i However unlike the v1 bootloader this avrdude line will not automatically cause the LeoStick to enter the bootloader. You can do th...

Re: LeoStick install and first time use - Windows

Thanks 2Elemental, I've added a note to both the LeoStick Windows guide and the general Freetronics one.

Re: Using the latest core

RedDogInCan is absolutely correct. The new Getting Started Guide now has a new board profile that will use the latest core on LeoStick V2.0 - tone() works, etc.

It is possible to update a V1.0 LeoStick to V2.0 to take advantage of this, too.

Re: Working tone() substitute for Leostick

Just a quick note that if you grab the latest LeoStick board profile , the tone() function will work on LeoStick V2.0. If you have V1.0 it unfortunately still doesn't work, so this code is an excellent substitute, or you can upgrade the bootloader to V2.0 (there's a link on the Getting Started page,...

Re: How to unlock a LeoStick with a hung sketch (and why)

If you use the latest board profile the tone() function now works correctly on newer LeoStick V2.0.

If you have an older V1.0 LeoStick then it is possible to update to V2.0.
