Hello
First let me whank you for the great driver, having i2s working in DMA mode (on his own) is a great feature and let us do other stuff in //.
I am just building a rotary clock (arm that turns with a motor) and I sync the picture sent with an optical sensor. I have a few issues that the picture/ led switching colors is not always allignes. Checking with the scope,
Question: I see that your driver on ESP8266 sends data non-stop, meaning also if the LED content did not change. Is this normal ? I have checked the code and see that "void WS2812::show" copies my buffer to the led buffer. This routine does not trigger the DMA to send data One time.
Did I miss someting or what could I do to have data only sent one time to the LED ?
Kind reg.
