I finally successed!!! The code and pin define from Vinc is completely correct, I only do one thing wrong: I choose "ESP32 S2 dev moudle" in arduino IDE (comes from some esp32 toutrial page) , and after I choose "Lonin S2 Mini" to compile, everything become magic!!! Thank you Vinc for writing and testing the code of DED for us, I post here to remind other one want to use ESP32 S2 mini for DED , remember to choose the right board type or the HW SPI will never work and SW SPI will slow as hell. I guess the mega2560 HW mode fail maybe same reason but I am satisfy with ESP32 now

Thanks Vinc, I had try to include these URL and upload again, still not work...:( I guess I should pass this one and back to mega2560 SW mode, I got bad luck with s2 mini but I will keep looking at this thread for more information. Thank you again!

Thanks for reply Vinc! I just follow this post and use the exactly same pin define and code you posted, the comtroller is esp32 s2 mini too. Do you use any special driver for your esp32 s2 mini? I can't fugure out other reason... Yes I only receive data from dcs-bios in DED, I just wonder other people (include Vinc) successful on HW SPI mode on esp32 s2 mini, I wish I can do it too

Thank you Vinc! It's the esp32 s2 mini (purple pcb) I keep struggling with. I bought 2 and they have the same problem. I had study about this and can successful upload it. I think the upload is successful, because when I change the code from SW SPI to HW SPI it appear different. I bought these from one supplier in ali and can't make sure if they are fault, just can't made the HW SPI to work.

Sorry to bothering here again about the same question. I'd bought another SSD1322(16pin) to test again. The situation is the same: 1.I use the same pin setting and code from vinc for ESP32 S2 mini and SSD1322. 2.The HW SPI mode just never work (black), the SW SPI mode work but EXTREMELY SLOW. I guess the code and pin is correct but some other thing wrong. The result this time is same as before. I guess I must have some problem on ESP32 or driver, could anyone successful make it work give me some more detail about using it?like the drive you use, the setting in arduino IDE for board, etc...Thanks in advanced.
