1/10 scan

[muthu920]

Is possible add custom scan to this library, our board is 1/10scan 80x40 led per panel, [ESP32-HUB75-MatrixPanel-DMA] works but 9th and 10th row is not printed for each scan because its printing 1/8s, is possible to convert to 1/10scan

Do you have several such panels? Try another one

[muthu920]

no i have only one panel, does this library support 1/10scan ?

[muthu920]

beacuse only 9th and 10th row missing but 8row display perfect

any idea to change coords for 1/10scan

[muthu920]

driver ic RUC7258D

I think it's a defective panel.

Can you try with another library like PxMatrix?

[muthu920]

ok i will check and update

Using VirtualMatrix example

untill 8th row data perfect after 8th row data shifted and some junk i think

[muthu920]

if i use virtualDisp->fillScreen(virtualDisp->color565(100, 0, 0));

The all pixel show perfect

[muthu920]

when i set a pixel at 9th and 10th row but it show at 10th and 11th row

[muthu920]

i think need to modify this library to 1/10Scan, any idea? Right now library scanning is 1/8

What's the second chip aside 7258 on your panel?

If you have a Stm32 bluepill or Rp2040 board, you can test the panel with DMD_Stm32 library.

DP245D second chip

I set to

HUB75_I2S_CFG mxconfig( PANEL_RES_X * 2, // DO NOT CHANGE THIS PANEL_RES_Y / 2, // DO NOT CHANGE THIS PANEL_CHAIN
);

virtualDisp->setPhysicalPanelScanRate(FOUR_SCAN_32PX_HIGH); and changed 8 to 10 in coords.y

now i get

- scrolling so it have some dot shift

DP245d is not a driver, should be yet another one

Thank you. The good news that it is a standard driver, it should be supported by the library.

It seems to me that the reason is a broken panel or bad connections. Check your board and panel for unsoldered pins.

I tried E pin gnd and Valid GPIO too, but same result

ok, i will buy one new board and check and update.

In my board it mentioned P4-1921-80x40-10S-S2.0

Tested with new panel but same result.

Panel not mistake, we test with other driver which comes with board it working perfect.

The problem with our library is it sacn 8 rows perfect but not scanning 9th and 10th row, does we need not modify virtiual to real pixel mapping for 1/10 scan because 1/8 scan working perfect but not 1/10 scan.

The library only natively supports 1/16 scan panels as outlined in the README, however, with some pixel-remapping (I.e. Virtual Matrix class) we have been able to incorporate support for other random panels.

You'll need to change the virtual matrix class to add the necessary support for this panel.

Ok thank you will update
