F4v3 - Smart receiver C short by one pixel #72

Open dkulp opened 5 years ago

dkulp commented 5 years ago

Smart receiver C is outputting one less pixel than what it is configured for. This is seen in the scopes (attached). The same number of pixels is configured for A/B/C, but the data for C is shorter than the others.

What's more, when configured for exactly 1 pixel, it doesn't output anything at all. The scope looks like it resets the data line back to receiver A, but doesn't actually send any data after that.

@dpitts Seeing this exact issue on my F4v3 running FW 2.59 as well where the last pixel on the last SmartReceiver (in my case the "B" SmartReceiver with 2 receivers configured) only receives the red channel. Incrementing the pixel count by one more than the number of pixels actually connected seems to workaround such.
