Might ask as well while I'm here, Is this platformio configured correct? I'm using the S2 mini and following the above wiring (previous comment) so its using pin 16 and 33. I've got 232 LED's in total and split to two 116 halves. Using SK6812 cold white leds. |

Hi
Nothing bad will happen in dfu. You can even disconnect the board. The same is done by esptool.py only in software unless there are problems with the firmware on the device, then you need to force dfu using buttons. When you set dfu and upload the firmware esptool won't be able to reset the board after uploading the firmware that's why you need to reset it manually afterwards.
It's much easier to do this under Linux but it also works under Windows so you need to do a little more.
On Linux just execute
Looks good: speed is set to 5000000 for this board and segment is defined correctly. Both segments have the same direction?

Okay, I would love to try clear everything up in this post so try bare with me haha.
Finally, is there a instruction on what to do for settings in hyperhdr webpage? Again, hoping I can get this working because my brain is beginning to melt haha.. Thanks again |

I will transfer this discussion to the HyperSPI project. |

Hi. I keep getting the emails about this thread, so I thought I’d interject. I believe I might be able to offer a solution for the purple screen effect you’re seeing. I had this same issue, a couple of times. I solved it by simply powering off the usb capture device for about 10-15 seconds. I can’t offer any explanation of what is happening, sorry. Only that this simple solution worked for me when I experienced a similar strange screen effect.

Hi Awawa,
So I've moved those data pins down 1 and added the 5v from one of the led power supplies. Cannot believe I missed that sorry :(..

I've also now got the Rpi configured and connected to the wifi. Im accesing it through the IP:8090. I worked my way through (https://github.com/awawa-dev/HyperHDR/wiki/Quick-start) and hit a wall pretty quick when I couldnt find the adalight driver.

I still dont believe I've done everything I need to with the ESP32 s2 mini, All I've done is (esptool erase_flash) and (esptool write_flash 0x10000 hyperspi_esp32_s2_mini_SK6812_RGBW_COLD.bin). After this I reset it while its still plugged in then use it.
Another thing is the colour of the led visualization is heaps weird, its all purple like.

I did a calibration with Automatic signal detection and this is what it looked like after, better but still bad.

I believe theres something I can her with LUTs maybe? is that correct?
Thanks for all your help so far, Sorry I dont understand very well but I'm getting closer :D

@LaytexLlama You must decide if your are using HyperSPI (awa_spi driver in HyperHDR) or HyperSerialESP32 (Adalight driver in HyperHDR). Everything is explained on the HyperSPI/HyperSerialESP32 project homepages in their configuration sections, even screenshots are provided how to configure them. These are completely different solutions and each requires different configuration in HyperHDR.
This is a typical result of capturing Dolby Vision stream (purple colors). DV is closed, proprietary solution and there is no USB grabber that can capture it properly. Even expensive HDFury won't solve it. There is one exception: Dolby Vision in LLDV compatibility mode. Most video sources can provide it if required and HDFury should work but as users report also cheap Ezcoo splitter with modified firmware should work and some other devices too. https://www.avsforum.com/threads/alternative-devices-for-enabling-low-latency-dolby-vision-lldv.3254266/ |

Hi Awa,
I've got my pinout board all done through copying this (https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhz7RZVlkJzr1LQOojH8pTlMMwJzPTIURhYZeaUFVazb3mVQjDJa6I2NF1o99cU6QX3XEdO86FDEJlePTmRcz6Rs78FN_E2XyUYeRqCSlTx_SzWqYcoS43DzIOucHy-YC-GJWIzQKUqKpu81YGa8s8tHFXZX6n8aP7P2fSp9iTeiPgbYzMWFemKL61o6g/s1100/shifter3.jpg)
Im now up to flashing the ESP32-S2 Lolin mini using (https://github.com/awawa-dev/HyperSerialESP32). Im not sure exactly how to use python and it doesnt seem very straight forward from the above guide (for me atleast).
I accidentally went straight into the troubleshooting part. I put the board into dfu mode but now I dont know how to complete this procedure.
How do I get esptool.py? I've downloaded esptool-master, is this the right thing? What do I need to run? nothing seems to work?
Am I meant to be executing all the commands through Python 3.11?
Once I get out of this recovery procedure, how do I flash (hyperspi_esp32_s2_mini_SK6812_RGBW_COLD) onto my s2 mini? Then finally, is this the only thing I need to flash to the S2 mini?
Many thanks in advance.
