Is this Chinese P10RGB outdoor module compatible ?

[vegetablesalad]

I'm trying to get this module to work, but its jumbled up, I think I have tried every setting. Is it supported or it has some weird mapping I have to transform myself? Just want to check before committing onto remapping.

Try apply this options:

--led-multiplexing=1

or

--led-multiplexing=4 --led-row-addr-type=2

or

--led-multiplexing=5

or

from rgbmatrix import RGBMatrix, RGBMatrixOptions import time

options = RGBMatrixOptions() number_of_panels = 1 MATRIX_ROWS = 16 MATRIX_COLUMNS = 32 options.rows = MATRIX_ROWS / 2 options.cols = MATRIX_COLUMNS options.chain_length = 2 * number_of_panels display = RGBMatrix(options=options) height = display.height width = display.width

def chinese(x, y, red, green, blue):
    scan_rate = MATRIX_ROWS / 4

    xoffset = (MATRIX_COLUMNS / 4) * (x / (MATRIX_COLUMNS / 4))
    yoffset = ((y + scan_rate) % (MATRIX_ROWS / 2)) / scan_rate
    new_x = x + (MATRIX_COLUMNS / 4) * yoffset + xoffset
    new_y = (y % scan_rate) + scan_rate * (y / (MATRIX_ROWS / 2))
    return display.SetPixel(new_x, new_y, red, green, blue)

for x in range(0, width): for y in range(0, height): chinese(x, y, 255, 0, 0) print '({}, {})'.format(x, y) time.sleep(1)

def chinese2(x, y, red, green, blue):
    scan_rate = MATRIX_ROWS / 4

    odd_quarter = ((y / scan_rate) % 2)
    shift_even_quarter = (1 - odd_quarter) * scan_rate
    shift_odd_quarter = odd_quarter * scan_rate
    new_x = x + ((x + shift_even_quarter) / (MATRIX_COLUMNS / 4)) * (MATRIX_COLUMNS / 4) + shift_odd_quarter
    new_y = (y % scan_rate) + scan_rate * (y / (MATRIX_ROWS / 2))

Thanks, will try this tonight!

Did it work ? If not, you probably have to go through the datasheet and build a multiplex mapper and possibly send a pull request.

I managed to get it somewhat close. I'll post my results tonight or later this week.

Sorry didn't have any free time to work on my project, but just picked it up. So I tried quite a few combinations of settings and your examples, but can't quite get it working. Here are some of the things I tried:

• from all the demos this setup got me the closest result:

  sudo ./demo -D 0 --led-no-hardware-pulse --led-chain=1 --led-rows=16 --led-multiplexing=5 --led-row-addr-type=2 result: https://youtu.be/HAGbXrgpqEs

• Your first python code sample result: https://youtu.be/72ZKh3QaEw4

• And final python code result: https://youtu.be/Wj29KVa5SuI

doesn't look like I'm close, this panel must be quite different
