Hello, I would like to ask a question about refreshing the screen.

In the LedWallRefresh () function set_row_signal (y% 2 * DISPLAY_SCAN_LINES/2 + x); this works for screens with Y = 32 or 64 resolution. But my screen portrait resolution is 26, and since 26/16 is not an integer, how do I modify the calculation to pass set_row_signal

I put the line selection function set_row_signal (y) in the outermost loop for (unsigned int y = 0; y < DISPLAY_SCAN_LINES; y ++), but the cost is very high, causing my screen refresh rate to drop by half! I still want to use a line selection like set_row_signal (y% 2 * DISPLAY_SCAN_LINES/2 + x). But my screen portrait resolution is 52 and not divisible by 16, and the refreshed line will be repeatedly selected in the X loop
