arduino's Issues

30Hz

Is 30Hz supported? If yes, how accurate is it?

Thanks,

Good job, but how to speed up execution times?

Hi,
I want to thank you for the work you did.
I noticed that the "SetPinFrequencySafe (TX_PIN, frequency)" function takes 88 microseconds to run, while the "pwmWrite (TX_PIN, 127)" function takes 44 microseconds.
Is there a way to speed up these execution times?

8Mhz Atmel 328 timing issue

Hi,
I am running a Atmel328 on 8Mhz and am using the SetPinFrequencySafe(pin,freq) function.

It shows some quite interesting behaviour.
I start with freq = 100, it outputs PWM 100Hz as wished,
than I read out / send the freq variable and that one shows 50!
Excactly half!
But since the program runs as loop I would expect the frequency to drop, but it does not ?! So I wonder if the 8Mhz mode may cause some trouble or if i have a major bug somewhere?

For my application I just multiply every reading from the variable by two. but it feels really strange and wrong
