Now I'm struggling with the Tiny Tuner, probably I've missed a library, I've tried to use the example:
- Interactive with NewsoftSerial
but it gives me some compilation error,
Please post the errors you get.
You should have your tiny's running at 8MHz, when you are using SoftwareSerial .
Select board -> Attiny85@8MHZ
select ->Tools->Burn Bootloader
Everybody writes many things difficult to understand without attaching a simple schema, also docs of TinyTuner has no schema
If you open the sketch Interactive_to_Serial_with_Details you will find a detailed description of how to make the connections for both ATtiny85 and ATtiny84,
Out of 20 - 30 ATtiny84's I've never had to use TinyTuner to get SoftwareSerial to work correctly.
Me neither, but there has been quite many posts about others having trouble, so maybe we have just been lucky ?
I have an old Fluke scopemeter
If it can measure frequence, you can use the sketch below. It outputs 1MHz on pin PB0, if your
tiny is running @8MHz
You connect a potmeter with the wiper to pin PB4. Then turn the potmeter until your meter show 1 MHz.
You can then use the OSCCAL value in the setup like this:
OSCCAL = 0x9F; //example value
