text display mirroring HORIZONTAL_ZIGZAG_MATRIX #1

Closed quarterturn closed 8 years ago

I'm confused as to how to get my HORIZONTAL_ZIGZAG_MATRIX APA102 strips to display properly. I have data entering on the upper left and then zig-zagging back to the lower left over 8 strips of 44 LEDS. My text display ends up flipped both ways.

Looking at your examples, there is a constructor cLEDMatrix<MATRIX_WIDTH, MATRIX_HEIGHT, MATRIX_TYPE> leds; I can use 'leds.' to access the various mirror functions, but they have no effect on the final output.

You can use a negative 8 for the height parameter to flip the origin for the matrix functions to the lower edge. so... cLEDMatrix<44, -8, HORIZONTAL_ZIGZAG_MATRIX> leds; This will make 0,0 of your matrix the bottom left corner. The mirror functions would work but you would have to call them after each call to cLEDText update.

Thanks! That works great!
