ANNOUNCE: Squeezelite-ESP32 (dedicated thread)

[troffasky]

But can you send me the config stances you use with squeezelite-esp32?

I have to check what my simplified parser does, but "display_config": "SPI:width=256,height=64,cs=5,reset=22,speed=80000 00,driver=SSD1322", should be "display_config": "SPI,width=256,height=64,cs=5,reset=22,speed=8000000,dr iver=SSD1322". Can you capture the serial log when it boots? It will tell me if the configuration is properly taken into account. You just need either a terminal or "idf.py monitor" on the pseudo-COM, or use telnet

this is, what i'm using spi with ESP32 Audio Kit V2.2 and an 0.96" OLED monochrom (only first 10 lines are yellow, the rest is blue)

This is odd. It looks like an old bug that was fixed 4 months ago

In contrast to every permutation I've tried so far, yours causes my D5 LED to blink rather than come on solid. Who knows what D5 means? Not me!
So I'm trying yours, but where is your IO12? I can't see any pin for IO12. The schematic for this thing [posted earlier in this thread] says IO12 is used for the SD card.

FYI, I just received the esp32-a1s that I had ordered some weeks ago and I'll be able to do some experimentations of my own very soon. If your problem isn't solved by then, I will certainly be in a better position to help and possibly make some changes to the build target as required.

But I really think the build is correct. I have been using one for a long while now, the issue is more with the funny mux they do with GPIO which requires very careful read of the doc, IMHO

Then perhaps it would be worth making a definitive documentation of the best combinations

I've used this board in JTAG mode and it worked but this is not a well documented design so I've not spent a lot of time on it. If you crawl through this thread (and a few others) you'll see that others had issue figuring exactly the GPIO mux.

Under binocular, D5 seems to be GPIO19 which is also key3 and that's confirmed by pressing it. I think your best chance is to reuse GPIO12 and GPIO14 for data and clock as they are probably clean (set them to the JTAG interface with the dip switches) and then decide which keys to re-use between 5,13,15,18,19. You can also use GPIO0 and RX/TX which are GPIO1 and GPIO3 (you'll loose trace after boot and need to use telnet). Forget 21 or you'll lose the control of the amplifier and 22 is for D5. I'm wondering if some of the GPIO muxed with keys don't have a debouncing capacitor, so you want to avoid them for SPI data & clock. Do you have an oscilloscope to see the SPI signals?

These black PCB might look nice but they are a real pain to trace and this board is a mess in term of IO mux...

NB: I've heavily edited this message while figuring out all that and I've updated https://github.com/sle118/squeezelit...make/README.md

Makes perfect sense. You could also re-use 0,1 and 3 if you want to maximize available keys

Thankyouthankyouthankyou...........finally have this working!!!!!! [I am not usually a fan of multiple exclamation marks in a row, but this is a special occasion, and there doesn't seem to be a "we are not worthy" emoji on this forum].

The D2 LED seems to blink as the screen is updated, FWIW.

For the record:
ESP32 Audio Kit V2.2 board, dip switches set to off/off/off/on/on
Config:
display_config SPI:width=256,height=64,cs=12,reset=22,speed=80000 00,driver=SSD1322
spi_config data=13,clk=15,dc=23,host=1

No-name SSD1322 256x64 OLED display, with 0-Ohm resistors set in "4-wire SPI" mode. Yes, it requires CS.

Thanks also to philippe_44 and sle118 for your help/work on this.

Excellent - Are you sure it's D2 blinking?

Excellent - Are you sure it's D2 blinking?

Because of the intensity of the green LED D1, I had some electrical tape over them. D1 is going off and D2 is coming on [I think - very hard to tell as they're very rapid]. D3 is on solid, D4+D5 are both off completely.
I am going to try 21=amp,39=jack:0,22=green:0 for set_GPIO again.

Edit: 22=green:0 breaks the display [which makes sense - I am using 22 for reset]. D1 stays on solid, D4 comes on, nothing on the display. This might be why so many of my previous attempts didn't seem to be working.
