Is there any reason VirtualWire won’t work with the mini? I think the answer is no (that they should work) but the exact same sketch that works on my plain Duemilanove, won’t work with the Mini. The transmitter says that 3.3v is OK so I don’t think power is the problem. I’ve tried the same transmitter with other Arduino boards and it seems to work just fine.
I just want to make sure I’m not missing something specific to the 3v/8MHz mini. IS there anything special about the mini that might make VirtualWire and/or the 315MHz transmitter not work?
The mystery continues… Apparently it isn’t a damaged Mini - I just tried it with 5 other ones I ordered from Sparkfun…
I’m at a loss. The pins look to be exactly the same and I’ve seen plenty of projects that claim to use these same 315MHz transmitters and VirtualWire with the 3.3/8MHz mini.
If anyone has any idea at all I’d sure appreciate it. Thanks!
Wow… Problem solved with the Arduino 19 release. The only thing I changed was to select the new Mini Pro 3.3 board from the boards menu and uploaded the sketch.
Does anyone know what real difference there are between those board selections? I thought the Mini was compatible with the others… Was there something special I should have been including in my code to make the Arduino work at 8MHz?
