Quick pin mapping question

1

Hi,

Is there a reason for the odd Pin mapping on the V4 Shield (see image below)? I would have thought that the mapping highlighted in blue would have made more sense, or does the V4 mapping help with mapping the rgb buffer to the DMA output buffer?

Note: i am just asking out of interest :slight_smile:

I think D2 is needed for a PWM output to drive the latch signal, and the order of the rest of the pins I swapped around for easier board routing
