Trying to get an SSD1357z 64x64 display working

[kevinfulness]

I got this little display for esp32 AR projects and it's mostly working via the SSD1351 driver, however half the screen is garbled.
I've tried different frequencies with no results. I'm wondering if my pins are wrong, or if there's anything else I can change in the 1351 driver to make it work for the 1357z.

Pins are as follows:
CS: 18
RST: 19
SCLK: 21
MOSI: 22
DC: 23

I just got the same display as you, id like to know if you figured it out .

I'm getting very similar results with the TFT_eSPI SSD1351 driver. Specified TFT_WIDTH/HEIGHT to be 64 as well. Appears that red and blue channels are swapped also, FWIW.

Currently looking for a datasheet to help me understand what's going on, but the SparkFun 64x64 OLED Library does work for me, so first I want to try modifying the TFT_eSPI SSD1351 initialization code to match the initialization code in the SparkFun library.

Most of the command codes specified the main SSD1357 header file of the SparkFun library seem to match the ones from the TFT_eSPI 1351 initialization code, which is promising.

You can try this one, made a while after searching and modifying around

Awesome, thanks! Did you find a datasheet by any chance?

[staberas]

The same datasheets as you, after many tries only the waveshare code worked for me so you can reverse engineer your way around it

[staberas]

@namuol any success?

I’ve put this on the back burner for some other stuff, but I’ll be sure to post back here if I make any progress!

Hi.

I have spent the last days trying to implement a driver for the SSD1357 (64x64), and I finally have made it work.
Please see my fork: TFT_eSPI

For some reason, it does not like the 16-bit transfer in the setWindow()-function, so it has to be sent as two 8-bit transfers.
Do not know if this has any impact, maybe someone smarter than me can figure it out. Spent some time figuring this out...

I have used the initialization sequence from this datasheet (madctl has been modified -> 0x72):
DM-OLED060-671 Datasheet

The command list is here:
SSD1357 Command List

What remains to be done is the rotation and "madctl" settings. I have not figured out the correct values yet,
but everything works like it should in rotation = 0, including the colors. Color-order can be changed with madctl (see datasheet)
I have taken inspiration from the SSD1333 pull request for the SSD1357_Rotation.h:
SSD1333 Pull Request

Would probably also be smart to implement user settings for the 96x64 and other common resolutions.
I have tried to add some flexibility for now but it should be easy to do for the other displays.

The driver works for my purposes as it is now (have tested it with RP Pico), but if you want to figure out the remaining stuff please do.
