connected to ttgo ts board LRCK BCLK and DIN and it works but with max volume. When I lower volume to 0 ,sound stops,but just at 5 it goes to max level and I can not control it. Any help? thanks

Yep you are right I made mistake in program somewhere. I connected this vs1053b and while radio is playing an led indicator light blinks but no sound.

[JayB7076]

But how I uploaded 5 required bin files. Karadio32 Karadio32 Partition Bootloader Standard_adb And I didn't change anything from it and pins are right to.

[JayB7076]

I gess I need to upload whole program again. But this is VS1053B not VS1053 so is it ok? And for new code upload I need to format Esp32 right?and after formatting Esp32 which bin file of esp32 (for making Esp32 factory type) did I need to upload?

[JayB7076]

Oooh now I realise that.. WARNING: the standard_adb.bin must be changed for a wrover processor or another configuration. I need to change even I have same pins as standard_adb. And there is no Wroom in -- WARNING: the standard_adb.bin must be changed for a wrover processor or another configuration. -- so I didn't changed anything.

does it work?

[JayB7076]

Na still not uploaded code but did I need to format Esp32 right?for new bin files?

[nano111]

Why dont you read what I wrote?

WARNING: the standard_adb.bin must be changed for a wrover processor or another configuration. Do you use this tool? http://karadio.karawin.fr/karawin32Flash.jpg You only need to flash your radio once and after just that last file if you change your hardware configuration.

I do not know how you format your esp32 just turn off first 3 files inflash tool karadio32-Karadio32-partition-bootloader and leave last one which you made from your configuration or use alredy made psram bin .You okly need to flash everything frat time… then you just change last bin which is hardware configuration, try if it works, if not change configuration and flash again with new file.

[JayB7076]

But how to turn off files from Esp32 tool?

[nano111]

Just uncheck first 3 files on the left side of the file location in tool.
