Resolution of RAW IR

I’m recreating some unmodulated IR signals by hand crafting raw IR codes with a duty cycle of 1.

It looks like IR output can only update in 1.5hz increments, even if the raw IR code describes something else.

For example, I can output pulses at 239hz, and 237.5hz, but not 238hz.

Anyone know if there is a workaround for this?

I wonder if that’s a limitation of the Flippers clock speed. Have you tried it using one of those allowed duty cycles? That small a difference might not be significant when you take into account drift. There is the option of using an external IR and PWM.
