DotStar Frequency
Is there a lowest clock frequency for DotStar? I'm experimenting with low frequency setups.

Re: DotStar Frequency
Dotstars are normally 20 KHz PWM while NeoPixels are 400-800 Hz.
Are you adjusting the Dotstar refresh rate by adjusting the SPI bus speed?
Just curious? What is your application that you wish to slow down the refresh rate?

Re: DotStar Frequency
Thanks for the info!
I'm driving with logic, not an MCU. Debugging is easier at low clock speeds.
