NHD-2.7-12864WDY3 driver update #476

Closed conectia closed 6 years ago

conectia commented 6 years ago

Hi,

The new NHD-2.7 128x64 oled display comes with the ssd1322 controller instead of the ssd1325.

I have been trying to replace it with your ssd1322 256x64 controller.

The display works, but I get scrambled output. The display shows one half with the output compressed and the other one with garbage.

I think it will be easy to make it work touching a few bits.

Any idea.

Thanks in advance.

Can you link the datasheet and/or the product description?

conectia commented 6 years ago

The product page : http://www.newhavendisplay.com/nhd2712864wdy3-p-9542.html

And two images, the old working ssd1325 and the result shown with the ssd1322 ssd1325 ssd1322

Thanks

Partially solved !

Replacing the driver:

U8G2_SSD1325_NHD_128X64_1_4W_HW_SPI u8g2(U8G2_R0, / cs=/ A1, / dc=/ A0); to U8G2_SSD1322_NHD_256X64_1_4W_HW_SPI u8g2(U8G2_R2, / cs=/ A1, / dc=/ A0);

Setting u8g2.setFlipMode(1); I get the horizontal mirror.

Updating U8X8_CAA(0x0a0, 0x014, 0x011), / remap / to U8X8_CAA(0x0a0, 0x004, 0x011), / remap /

I get a vertical mirror. But still the image is compressed horizontally.

Any idea ?

Thanks in advance. img_5235

Is this the same display: https://github.com/olikraus/u8g2/issues/412 ?

Does this issue belong to u8g2?

conectia commented 6 years ago

Yes, I'll update issue 412
