Hi |
|
Appreciate you help, thanks! I switched on/off a couple of times and checked So what I saw in HyperHDR just now (specifically what's below "LED device") |
|
SPI wont report to HyperHDR any error if the SPI device path is correct, so these screenshots tell us only that the app sent the frames (without confirmations). But esp32-s2 didn't receive any of them. |

I just probed the wiring/soldering that's supposed to connect level shifter/PCB ground and 5v to PSU plus the data wire, all from the soldered pathways on the PCB's underside to the end of each wire. Seems like those are all fine so my first impulse to solder the wires directly to the header's pins to make sure the connection isn't as wonky as it looks seems a little less promising now, … Does the output I got via Does that make sense / is there anything else I could look into? |

If the screen outputs 0 FPS, then the SPI connection to the RPI is not working. But that does not mean that there is something wrong with the rest (level shifter): it is simply not used. HyperSerialWLED or HyperSerialESP32 may or may not work. |
Uh oh!
There was an error while loading. Please reload this page.
This is my first DIY electronics/soldering project so I obsessively read the documentation many times and most of the discussions, too. I copied everything from diagrams and pictures provided there because when I started working on this I knew basically nothing, I had to look up if red means + or - when wiring up the PSU. By now I think I kind of understand what I've built but I can't get it to work on my own.
I tested the LED-frame with a flipper zero WS2812 test app (flipper connected to the LED's data and GND, MW PSU to power the LEDs) successfully, HyperHDR is running and seems to establish a connection to HyperSPI on the Wemos but I just can't get the LEDs to light up. I'm using PiCap on a WebOS TV as a capture device, preview's working.
I'm sure it's some stupid little mistake but I can't figure it out. Already went through a number of iterations concerning the wiring, I liked the first one better but noticed the data wire turned out longer than advised.
Huge thank you to Awawa-Dev for the unfathomable amount of work that must have gone into this project.
Setup:
The soldering looks awful but I tried to verify all the connections with a multimeter in continuity testing mode.
