I've updated a version of maniacbug's RF24 library so all the example sketches compile and run cleanly on Teensy 3.x (and possibly for other ARM targets... tested with Due and works.) I know there have been a few versions of this fix floating around, but I needed one I could specifically point...

Just an update to say I'm now selling the Teensy 3.x shield/carrier board from my website; here's a link if interested http://embeddedcoolness.com/new-rfx-carrier-board-pjrc-teensy-3-x-added/. I was very pleased with how well the boards tested when they came back from the fab. I think this is...

Congratulations! Always nice to get those first orders. :-) If you don't mind me asking, are you getting orders for bare boards, partly assembled, or fully assembled?

Yes, that's what I've done for my board. The VUSB is connected the 5V pin on the Arduino power header. VUSB is also by default configured as the input to the LD1117v33 regulator. It can be disconnected by a jumper though, and a separate power supply >= 5V used instead to the Vin pin of the...

You're using the same "surface mount" pins for the pads as KurtE by the looks of things?

That's an interesting approach -- are these surface mount pins easy to work with? Sturdy? Since I'll be supplying my board as either bareboard or kit, I'm always concerned that the components are easy for beginners to solder. That's why I use the big old TO-220 package voltage regulator...

OK, I've sent the gerbers off to get a test run of 10 of the new boards made up. If it all works as expected, I'll add these to the store on my website, and also sell them from Tindie. I think this will complement the smaller (~5x5 cm) shield that Paul linked to in his original post above; a...

Nice looking board! :-)

That's actually one of my boards, which was designed as a standard Arduino shield with nRF24L01+ connector sockets, to simplify adding nRF24L01+ modules to Arduino projects. It has a parallel set of proper 0.1" grid aligned headers to make it easy to use with protoboard, breadboards, etc., and...

OK, so both the Teensy 3.0 and 3.1 have always had the 500mA poly fuse between the USB shell connector the VUSB pin? -Mark

Old and new schematics? hi Paul, I notice the schematic in the first post and the schematic in the link differ wrt the placement of the poly fuse. In particular, in the original (Teensy 3.0) schematic posted, the poly fuse comes after VUSB pin connected to the micro USB shell connector, but...

Just tested Beta #10, everything I've looked at so far seems fixed. Good job, Paul!

vsnprintf() test sketch for Teensy (tested to compile and run OK on Due.) Note: This updated version compiles and runs on Teensy3 beta #9 with #undef __STRICT_ANSI__ trick. /* vsnprintf() test sketch for Teensy3 Jan 2, 2013 */ #undef __STRICT_ANSI__ #ifdef ARDUINO #if (ARDUINO >= 100)...

vsnprintf() also has these problems Just thought I'd report I'm seeing problems with vsnprintf() as well. Before the #undef __STRICT_ANSI__ trick, I'm getting: error: 'vsnprintf' was not declared in this scope and after I do the #undef __STRICT_ANSI__ trick, I get the _close, _lseek...

Yes, don't know how that crept in. Usual random source of error between chair and keyboard, no doubt. Actually, three characters went missing. As well as the ';', there should be a ' ' and '\' (space and backslash) to indicate a continuation line. { __asm__ volatile ("MSR PRIMASK...

I've emailed you the file to the address in your PM. I've also cc'ed Paul at paul (at) pjrc.com. Hopefully, "should just work", but any questions or issues, let me know.

I've ported a version of Dean Camera's ATOMIC_BLOCK macros from AVR to Maple, which is ARM Cortex M3, so I can't see why it shouldn't also work straight-up on the Teensy 3.0. The assembly language instructions should be the same, and the underlying compiler is gnu. If you want to test it on your...
