I have a low voltage (3.2v) application. I was hoping to use the Digispark. I have a solution using a separate Tiny85, but want to use the Digispark USB programming.
To run at lower voltage I think you need the lower clock rate. I have done this using the standalone Tiny85. I could hook up the Digispark to the programmer direct and change the frequency fuses, however...
I assume reducing the clock rate by programming the fuses would break the Digispark boot loader as it would have the wrong timing. Correct?
Can I dynamically switch the clock frequency in my code after the bootloader or is it fuse controlled only?
Is the bootloader available and could I change it to a lower frequency? Would there be a lot of work changing the code to a different freq? Would it be powerful enough to run the USB bootloader?
